abstract = {
One of the most significant
human-made methane emission sources is the municipal solid waste (MSW),
deposited on sanitary landfills and open dumps [1,2]. Within this work,
an alternative MSW treatment concept is presented, which could provide a
relatively clean waste/biomass-to-energy transformation. The proposed
procedure comprises of a combustion and a gasification (or pyrolysis)
step, which are consecutively taking place in a two-stage hybrid porous
reactor system. The core of the system are two packed bed reactors, in
which solid fuel (waste or biomass) is mixed with inert ceramic
particles of similar size.
This paper overviews the
initial experimental investigation of the combustion step of a hybrid
mixture, composed of wood pellets (fuel) and alumina balls (inert
ceramic particles) in a 250 mm-high batch reactor. The temperature
profile along the reactor, the concentration of CO and the flame front
propagation velocity were measured as a function of the ceramic particle
size (11 and 20 mm), the inert-to-fuel mass ratio (0:1, 2:1, 3:1) and
the airflow rate (30, 42, 60 l/min).
Experiments
indicate that an increase of the mass ratio of inert-to-fuel material
and a decrease of the inert ceramic particles size lead to a decrease of
the maximum temperature of the packed hybrid bed. Measured CO
concentrations showed strong dependence on the inert ceramic particle
size, i.e. the particle size reduction from 20 to 11 mm resulted in a
significant reduction of CO-emission peaks. The maximum flame front
propagation velocity of 0.2 mm/sec was detected for the airflow of 42
l/min, the particle size of 20 mm and the mass ratio of 3:1.

abstract = {Perfluorinated compounds (PFCs) are manmade chemicals, containing the
covalent C-F bond, which is among the strongest chemical bonds known to
organic chemistry. Abundant use of these chemicals contaminates air,
water, and soil around the world. Despite recent initiatives and legal
regulations set to reduce their omnipresence, conventional water
purification processes are either inefficient or very expensive,
especially for low PFC contamination levels. This research is focused on
the non-thermal atmospheric plasma (NTAP) decomposition of very low
concentrations (<1 µg/L) of PFCs (especially perfluorooctanoic acid
(PFOA) and perfluorooctanesulfonate (PFOS)), present in the wastewater
produced during the process of PFCs removal from contaminated soil. The
efficiency of the decomposition process was investigated for air,
oxygen, and nitrogen plasma, with exposure times of 1–10 min and
different plasma nozzle- and reactor sizes. Experiments demonstrated
that the NTAP treatment is an efficient alternative method for
degradation of more than 50% of the initial PFC concentration in the
water samples, in less than 200 s. The final concentration of PFC showed
strong dependency on the tested parameters. The treatment effect showed
to be strongly non-linear with time, followed by the reduction of the
pH-value of the treated sample, which might present a limiting factor
for further PFC decompositio},

abstract = {Per- and polyfluoroalkyl substances (PFAS) are omnipresent synthetic chemicals. Due to their industrial importance and widespread use as a key component in various applications and a variety of products, these compounds can be found today in high concentrations (>1 mu g/L) in surface and groundwater but also spread throughout the ecosystem, where they represent a serious threat to most living organisms. The removal or degradation of PFAS contaminants from water and soil is becoming a legal obligation in a growing number of countries around the globe. This, however, demands novel techniques for the degradation of PFAS since conventional water treatment techniques are either insufficient or extremely expensive due to the persistent nature of these compounds caused by their extraordinary chemical stability. The goal of this work was therefore to investigate the practical potential of the application-oriented use of atmospheric non-thermal plasma as a powerful advanced oxidation method for the purification of water contaminated with PFAS compounds. Special attention was devoted to the development of the concept that can be scaled up to the capacity level of approximately 100-200 m(3) of water per hour, contaminated with PFAS and other contaminants including organic and inorganic material generally present in soil, and surface or groundwater. Our major research interest was to define the minimum required treatment time for optimal purification results, as well as to understand the influence of the initial concentration of PFAS in water and the potential presence of co-contaminants often present in situ on the efficiency of the degradation process. A chemical analysis of the treated samples demonstrated the ability of the atmospheric plasma to reduce more than 50% of the initial PFAS amount in the water samples in less than 300 s of treatment time. PFOA, however, showed more rigidity towards degradation, where a double treatment time was needed to reach similar degradation levels. The obtained results showed that the initial concentration level does not play a major role in the process. However, the PFAS degradation profiles for all tested concentrations show a strongly nonlinear behavior with time, characterized by the fast decrease of the process efficiency in the case of longer treatment times. For prolonged treatment times, a constant increase in the samples' conductivity was measured, which might be the limiting factor for the degradation rate in the case of prolonged treatment times.},

abstract = {The jumping-droplet phenomenon occurring on superhydrophobic (SHPhob)
surfaces under special conditions may be beneficial for numerous systems
using condensation, due to the reported increased heat transfer
coefficients. One technique to create a SHPhob surface is coating, which
can be applied to larger areas of existing elements. However,
challenges are associated with coating stability and the realization of
continuous dropwise condensation. This research examined the
condensation of steam at different flow rates (2, 4 and 6 g/min) and its
influence on heat flux and water contact angles on the SHPhob
spray-coated aluminum samples. Special emphasis on the impact of time
was addressed through a series of one and five-hour condensation
experiments on the samples with different storage periods (coated either
one year ago or shortly before testing). Over the experimental series
at a higher steam flow rate (6 g/min), heat flux decreased by 20%
through the old-coated samples and water contact angles transferred from
the superhydrophobic (147°) to hydrophobic (125°) region. This can be
attributed to the joint effects of the partial coating washout and the
adsorption of the condensed water within the porous structures of the
coating during steam condensation. The new-coated samples could sustain
more than fifty hours of condensation, keeping the same heat fluxes and
SHPhob characteristics.},

abstract = {Demand to improve food quality attributes without the use of chemicals has risen exponentially in the past few years. Non-thermal plasma (NTP) (also called ‘cold plasma’) is becoming increasingly popular for this purpose due to its unique low-temperature and non-chemical nature. In the present research, the concept of in situ dielectric barrier discharge (DBD) plasma treatment inside a rotational reactor for the direct treatment of wheat flour was experimentally analyzed. The primary research goal was to determine the effects of short-period NTP treatment of DBD type on flour and dough properties. For this purpose, the influence of different operating parameters was tested, i.e., treatment time, the amount of flour placed in the reactor and the environmental (air) temperature. Changes in the structural attributes of the most commonly used flours (type 550 and 1050) and their respective doughs were studied using a set of analytical techniques. Rheological analysis demonstrated the ability of NTP to significantly intensify the visco-elastic properties of dough produced from wheat flour type 550 that was treated for less than 180 s. This indicated that plasma treatment enhanced intermolecular disulphide bonds in gluten proteins, which resulted in stronger protein–starch network formations. However, longer treatment times did not result in a significant increase in the visco-elastic properties of wheat dough. The obtained results showed a 6–7% increase in flour hydration due to NTP treatment, which also makes a contribution to hydrogen bonding due to changes in the bonded and free water phase. Experimental findings further confirmed the dependence of NTP treatment efficiency on environmental air temperature.},

Therefore, a novel approach by analyzing mid-infrared radiation patterns captured by a thermal camera and subsequent image processing was developed. A thermal camera was adapted to two different oven systems: a standard electric deck oven and a novel gas-fired baking oven with integrated volumetric ceramic burners (VCBs). The baked goods were analyzed and key indicators describing the final product quality were determined. Specific volume, surface browning and mid-infrared image processing demonstrated a comparable performance of both oven systems. Furthermore, the determined surface heat homogeneity of the items to be baked was 0.65 ± 0.05 (–) for the electronic oven and 0.70 ± 0.03 (–) for the VCB oven. The proposed approach proved its fundamental qualification for comparing and evaluating different oven systems.},

abstract = {This paper investigates temperature profiles and heat fluxes
in a packed bed heated by radiation that simulates solar energy flux.
For this purpose, the discrete element method (DEM) was used along a heat transfer model (conduction and radiation mechanism). Short-range model is proposed for considering thermal radiation in a discrete elements system, which represents an easy-to-implement and low-computational-cost alternative. As results of the simulations, thermal
profiles through the packed bed were obtained, as well as the
accompanying heat flux. Experiments were performed in a packed bed of
inert ceramic particles (alumina spheres). A radiant porous burner was
placed at the bottom of the packed bed to simulate an imposed
concentrated solar heat flux. Numerical results show good agreement with
experimental data. In addition, the thermal profiles, obtained by the
heat transfer model in DEM, were compared with the results obtained by
discretizing the conservation of energy equation
of the solid phase using finite differences, showing a correlation
between the power and temperatures reached. It is concluded that the
radiation model proposed provides the basis to continue with the study
of granular materials at high temperature, where radiation is the dominant mechanism},

abstract = {Hollow spheres as inert packed bed is an innovative technology with high potential in filtration combustion. Their lower specific density, geometry, and the radiation inside the sphere enhance the overall heat transfer of the sphere, and therefore, increase the effective conductivity of the packed bed, while the other thermo-physical properties remain unchanged. The present work investigates numerically and experimentally the effects of the packed bed made of hollow alumina spheres filled with air, from lean to rich premixed methane-air combustion within this porous media, with focus on the production of hydrogen and carbon monoxide species on rich conditions. The experimental part considers the equivalence ratio from 0.8 to 1.3. The numerical approach contemplates a one-dimensional model based on two-temperature approximation (gas and solid) with a four-step chemical reaction mechanism for homogeneous reactions at equivalence ratios between 0.4 and 1.6, for different spheres geometries. The results of experimental and numerical investigations are in good agreement. Both indicate that the use of hollow spheres packed bed (HS), in contrast to the packed bed made of the solid spheres (SS), shows higher temperatures and flame front velocities in all the equivalence ratio ranges. At the stoichiometric equivalence ratio, the numerical investigation in the HS case results in higher temperatures of 168 K and 21 K, in the solid and gas phases, respectively, in comparison with the SS case. The combustion products for different spheres geometries and equivalence ratios present the same trend and values for both HS and SS cases. The yields of carbon monoxide and hydrogen goes up to 37% and 42%, respectively.},

Results suggest that in order to efficiently transform the fuels into syngas, it is convenient
to operate the reactor under an upstream regime considering the chemical energy at inlet

Furthermore, no negative effects on the product quality were observed, even though further food quality tests are required. The presented experimental research confirms the overall positive influence of NTP treatment, even for very low treatment times, on wheat flour and its products.

abstract = {Expansion of operation range toward higher temperatures is one of the
major goals in further development of porous burner technology. This is
mostly related to the fact that radiation is the most intensive
mechanism of heat transfer from a porous burner to a heated object.
Therefore, increase of average temperature generally leads toward higher
overall efficiency. In addition, higher average temperatures are
opening new possibilities for industrial application of low pollutant
porous burner technology.
In this study, a series of novel high-performance ceramics in various
designs were investigated in short and continuous long-term experiments
under different controlled combustion conditions. Materials like
fiber-reinforced alumina ceramics, paper-based pre-ceramic materials and
wood-based bio-ceramics were successfully characterized.
Long-term combustion tests with test time of 100-500 test hours of
continuous operation per test, were conducted at near stoichiometric
combustion conditions using mixture of natural gas and air. Most of the
tested structures and materials was for the first time tested as a
porous burner component at this temperature range within the frame of
here presented work.
Presented results provide significant amount of useful data regarding
performances and limitations of investigated novel ceramic materials and
structures and also their potential for application as high temperature
(1500°C and above) and thermal shock resistant porous burner components
like combustion zones, flame traps or burner housing},

abstract = {Thermal energy of flue gases (FG) dissipating from industrial facilities
into the environment, constitute around 20% of the total dissipated
thermal energy. Being part of the FG, water vapour carries thermal
energy out of the system in the form of the latent heat, which can be
recovered by condensation, thus increasing the overall efficiency of an
industrial process. The limiting factor in this case is the low dew
point temperature (usually 40–60 °C) of the water vapour in the FG. The
increase of the dew point temperature can be achieved by increasing the
water content or pressure. Taking these measures as a basis, the
presented work investigated the following concepts for increasing the
dew point temperature: humidification of the flue gas using water,
humidification using steam, compression of the FG and usage of the steam
ejector. Modelling of these concepts was performed using the commercial
software Aspen®. The humidification of the FG using water
resulted in the negligible increase in the dew point (3 °C). Using steam
humidification the temperatures of up to 92 °C were reached, while the
use of steam ejector led to few degrees higher dew point temperatures.
However, both concepts proved to be energy demanding, due to the energy
requirements for the steam generation. The FG compression enabled the
achievement of a 97 °C dew point temperature, being both
energy-efficient and exhibiting the lowest energy cos},

Nahrungsmittelprodukte ist und war schon immer beträchtlich. Die
Nahrungsmittelindustrie gehört daher im Allgemeinen zu den zehn oder
sogar den fünf energiebedürftigsten Industriesektoren. Dies führt zu
einer stetigen Notwendigkeit, bestehende Technologien zu verbessern oder
neuartige Technologien einzuführen, was häufig eine erhebliche
ökologische und wirtschaftliche Herausforderung darstellt. Im Falle der
Nahrungsmittelindustrie besteht eine zusätzliche Herausforderung darin,
dass eine Verbesserung bzw. ein Ersatz bestehender Technologien weder
die Qualität noch die Sicherheit der Nahrungsmittel kompromittieren
darf. Dies bedeutet, dass viele der neuartigen Technologien und
Lösungen, die in anderen Industriesektoren weitläufig zum Einsatz
kommen, nicht einfach auf die Nahrungsmittelindustrie übertragen werden

Genau diese Art von Technologietransfer der relativ jungen
VKB-Verbrennungstechnologie von der Hoch- zur Niedertemperatur-Anwendung

wurden kürzlich von den Forschungsgruppen von Prof. Antonio Delgado vom
Lehrstuhl für Strömungsmechanik (LSTM) der
Friedrich-Alexander-Universität Erlangen-Nürnberg und von Prof. Thomas
Becker, Lehrstuhlinhaber für Brau- und Getränketechnologie an der
Technischen Universität München (TUM), gemeinsam mit den dieses Projekt
unterstützenden Partnern aus der Industrie Untersuchungen durchgeführt.
Kern dieses neuartigen Backofenkonzepts ist der Einsatz des porösen
volumetrischen Keramikbrenners (VKB) als alternative strahlungsreiche
Quelle thermischer Energie für den Backprozess. Die praktischen Vorteile
der VKB-Technologie sind in der Literatur gut dokumentiert,
insbesondere was die in der Vergangenheit häufig am LSTM untersuchten
Hochtemperatur-Anwendungen (z. B. VKB-Anwendungen in der Glas- oder
Aluminiumschmelzindustrie, in Gasturbinen, Papiertrocknern, Boilern oder
Brennstoffzellen) angeht.
Andererseits wurde, um die Technologie auf so sensible

The simulation of five modes of operation of the burner depending on the boiler load was carried out using modern packages of computational fluid dynamics ANSYS. The goal of this work is to investigate effects of replacement of existing vortex burners in previously described facilities with the direct-flow burners with organization of the new combustion process. As results after the simulation, the parameters of the numerical values of the turbulence parameters and the mass fractions of various substances for the gas-air flow in the boiler inlet plane was obtain. On the basis of the obtained results analysis of the proposed design of the burner was made. Numerical values of the parameters of the gas-air flow in the plane of the inlet to the boiler will be used later as input data for the numerical simulation of the boiler furnace.},

abstract = {The baking process demands a high amount of energy, but only one-third of the total energy supply to the baking oven is actually used for baking, while the rest is dissipated to the environment. This implies that the energy input to the baking process can be significantly reduced, e.g., by enabling a more efficient heat transfer to the product, compared to commercially available ovens. Application of highly radiative, gas-fired heat sources, with a wide power modulation range, such as porous volumetric ceramic burners (VCB), can lead to a reduction in both the baking time and the energy input to a baking oven. In order to optimize energy input to a wide variety of baking products, the role of individual mechanisms in heat transfer between a heat source and a baking product needs to be determined. In the scope of this work, the analysis of the heat transfer within a baking oven model, heated by porous VCBs, was conducted. Contribution of heat transfer mechanisms (heat conduction, convection, thermal radiation) to the total heat transfer was determined by the difference method, where two aluminum cubes of different surface characteristics were used as target objects. Further, the influence of water, commonly added to the baking chamber in form of steam or aerosol, on the heat transfer characteristics within the oven was investigated. Without water addition, the heat transfer between the porous VCBs and the test object occurred mainly through thermal radiation (~45%), followed by heat conduction and convection (~27.5% each). Compared to the reference, commercially available electrical deck baking oven, the share of thermal radiation in the model oven was increased (+ 10%), whereas the share of heat conduction was reduced (−20%). With water addition, the heat transfer to the test object through heat conduction, convection, and thermal radiation declined, as an additional heat transfer through condensation took place. Results of this research provide necessary understanding of the heat transfer mechanisms within the novel baking oven, heated by porous VCBs. They are the base for optimization of the heat transfer from the VCBs to different baking goods, through changing the VCB's operating parameters.},

abstract = {This work deals with the numerical investigation of a three-dimensional, laminar hydrogen-air diffusion flame in which a cylindrical fuel jet is surrounded by in-flowing air. To calculate the distribution of gas molecules, the model solves the species conservation equation for N-1 components, using infinity fast chemistry and irreversible chemical reaction. The consideration of the component-specific diffusion has a strong influence on the position of the high-temperature zone as well as on the concentration distribution of the individual gas molecules. The calculations of the developed model predict the radial and axial species and temperature distribution in the combustion chamber comparable to those from previous publications. Deviations due to a changed burner geometry and air supply narrow the flame structure by up to 50% and the high-temperature zones merge toward the central axis. Due to the reduced inflow velocity of the hydrogen, the high-temperature zones develop closer to the nozzle inlet of the combustion chamber. As the power increases, the length of the cold hydrogen jet increases. Furthermore, the results show that the axial profiles of temperature and mass fractions scale quantitatively with the power input by the fuel.},

The present study experimentally investigated the influence of different mechanical surface treatment methods on the static wettability of uncoated and amphiphobic-coated aluminium alloy (AlMg3) samples, specially focusing on the interaction between surface finishing and coating. Five different surfaces were prepared: as-received substrate, polished, sandpapered, fleece-abraded and sandblasted. After characterisation, the samples were spray-coated using an amphiphobic coating. The characterisation of the uncoated and coated samples involved measurements of the roughness parameters and the apparent contact angles of demineralized water and rapeseed oil. The coating was initially characterised regarding its adhesion to the sample and elevated temperature stability. The applied surface treatments resulted in the scattered sample roughness in the range of Sa = 0.3-15.8 μm, water contact angles of θap,w = 78°-106° and extremely low oil contact angles. Coating the samples more than doubled the surface roughness to Sa = 13.3-29 μm, whereas the initial surface treatment properties (structure, anisotropy, etc.) were entirely repressed by the coating properties. Coating led the water contact angles to increase to θap,w{\_}coated = 162°-173° and even more pronounced oil contact angles to increase to θap,o{\_}coated = 139°-150°, classifying the surfaces as superhydrophobic and oleophobic.},
