1/1/2013 · The PSD of solids has a fundamental influence on the recirculation ratio and accordingly on other output and emission parameters of a CFB boiler. Under commercial operations, it is difficult to keep a constant PSD in a boiler's chamber mainly due to attrition, erosion and combustion processes in the fluidized bed ( Nowak and Bis, 1997 ; Report EVT, 1997 ; Report PIE, 1997 ).
