Simulation of gassolids heat transfer in cyclone pyrolyzer using CFD ...
It is well known that the downer pyrolyzer is suitable for coal pyrolysis because of its unique characteristics, such as a more uniform flow structure of gas and solids, short residence time and less back mixing (Liu et al., 2020; Zhang et al., 2015).Considering coal pyrolysis is a fast reaction, it is necessary to achieve rapid heat transfer from heatcarrying particle to coal particle in the ...
