Experimental Study of Alkali Salt Adsorption in a Circulating Fluidized Bed Boiler

Spraying the concentrated wastewater into a circulating fluidized bed (CFB) boiler furnace is an economical way to process the saline wastewater generated in coal gasification. However, if the wastewater is overdosed and the alkali salt mass fraction exceeds the capability of the bed material, the excess alkali components in the flue gas may raise not only boiler fouling and corrosion problems but also environmental problems. Therefore, the...
