Abstract: The subject invention relates generally to methods and apparatuses for calcining gypsum. The apparatuses and methods place a gypsum particle optimizer in close association with the impact mill so that all the gypsum supplied to the impact mill has to enter the gypsum particle optimizer prior to the gypsum entering the impact mill, and so that heat generated from the impact mill enters into the gypsum particle optimizer from the impact mill. The gypsum particle optimizer utilizes a rotor to disperse the gypsum throughout the gypsum particle optimizer so that the gypsum is exposed to the heat from the impact mill prior to entering the impact mill. The exposure to the heat removes free water from the gypsum prior to the gypsum entering the impact mill.

Abstract: Provided is a method for operating a pulverized coal-fired boiler facility, wherein upgraded low-grade coal can be safely used as fuel and an existing facility needs little remodeling. The present invention relates to a method for operating a pulverized coal-fired boiler facility (100) that uses upgraded brown coal as fuel. Boiler exhaust gas taken out of an exhaust gas duct (31) is added to air from a primary air fan (10) to prepare mixed gas with an oxygen concentration of less than 12% in a volume ratio, the mixed gas is caused to separately flow to a carrier gas duct (33) that goes through a GAH (8) and a bypass carrier gas duct (34) that bypasses the GAH (8), and thereafter the mixed gas is supplied to a mill (21).
