Abstract

In a pyrolysis plant, a mounted centrifugal fan takes heavy damage because of erosion origi-nating from metal particles mixed with the inlet air flow impacting its blades and volute walls. In a previous study a new design strategy has been undertaken to specifically overcome the excessive erosion damage on the blades resulting in a new design for the fan which has been investigated by means of CFD simulations coupled with a Finnie erosion model to as-sess the damage via ANSYS CFX. This study focuses on further qualitatively assessing the erosion model adopted previously. An available air-compressor in laboratory scale is investigated experimentally in similar con-ditions. Two layers of paint in different colors cover the walls of the rotor and the inside walls of the volute to better locate the damaged areas. The introduction of the metal particles is regulated via a rotary feeder installed for this purpose into the test setup. The experiments show the effect of the first impact of the particles and severe damages only to the pressure side of the rotor, the suction side is not affected. These results have been ob-served via CFD in beforehand. The analysis is conducted in the same chosen stage operating point, defined at a predefined volume flow VF [kg/m³] and total-to-static pressure Δp[Pa]. Simulations are conducted in steady state with compressible air at high static temperature going to 530°C. For CFD calcu-lations the software in use is CFX of the ANSYS Group. All mesh used is structured and pro-duced by TurboGrid and Icem for the different setup parts.
