説明

A simplified model for sulphur absorption in circulating fluidized beds has been proposed. It could provide a preliminary assessment of the effect of design, operating and feedstock parameters on sulphur capture performance. The model prediction was compared to sulphur capture data from a 0.3 MWt pilot-scale CFB combustor and a 22 MWe commercial-scale CFB boiler and good agreement was observed. The effects of Ca/S ratio, solid circulation rate, bed suspension density and superficial gas velocity on sulphur capture were shown both analytically and experimentally.
