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).

Abstract: The invention relates to an indirect heating system in which a solid fuel circulates in the form of particles. The inventive system comprises a grinding station, a furnace (7), at least one intermediate silo, a separator, at least one cyclone and, optionally, a gas recirculation fan. The invention is characterized in that a dust extractor (10) captures the finest particles which are subsequently introduced into the furnace (7) by means of at least one specific conduit (52) and burnt by at least one specific burner (71). The aforementioned ultra-fine particles are then stored in a specific silo (10), dosed into a feeding device (61), mixed in well defined proportions with hot air and conveyed to the specific burner (71) through the specific conduit (52).

Abstract: Bottom ash and flyash having high LOI is reburned in a pulverized coal furnace. The bottom ash is added to the coal supply before the coal is pulverized. Flyash is added to the pulverized coal stream for injection with the pulverized coal or is separately injected into the furnace at or slightly above the level of the coal burners in the furnace. The bottom ash and flyash is added to the coal in direct proportion of 1% to 3.5% of the coal.
