Fluidized bed distributor plate assembly

摘要

A fluidized bed furnace (10) for generating steam (26) is designed to operate over a given load range, for example from 50% of full load to maximum capacity rating (MCR). The air distributor (12) is designed with a constant pressure drop restriction means or "float" (36) in each air inlet (18). As the load varies, the pressure drop across the float (36) will remain constant, reducing the overall fan horse power requirements.
