Abstract
A method of feeding particulate material (17) to a fluidized bed furnace (10) is provided wherein particulate coal, particulate limestone and particulate material withdrawn from the furnace system are fed to the furnace as a mixture in a unified feed system. Raw coal and limestone are independently crushed to the desired size and premixed to yield a desired calcium to sulfur mole ratio. The premized coal and limestone (7) are passed to a dryer/mixer and contacted therein with hot particulate material (9,19) withdrawn from the fluidized bed furnace system for a period of time sufficient to substantially dry the wet coal and hydrate at least a portion of the lime contained in the hot particulate material. The so-conditioned mixture (15) is then entrained in a conveying gas and fed to the fluidized bed (12) in a conventional manner.
