A VARIABLE FLUID BED FOR OPTIMIZING SUPERHEATER / REHEATER SURFACES IN A BUBBLING FLUIDISED BED COMBUSTION BOILER

摘要

This invention relates to a variable fluid bed for optimizing superheater/reheater surfaces in a bubbling fluidized bed combustion boiler comprising of evaporative, superheat and reheat surfaces (9) immersed in the said fluidized bed and in the convention zone located above said fluidized bed characterized in that the heat transfer vary in the active fluidized bed by changing the fluidized nozzle (14) elevation.
