PURPOSE:To improve burning efficiency and to control NOx and SOx, by a method wherein collected dust is molded and solidified and the molded solid is reburnt by throwing it into a fluidized furnace for burning unburnt carbon. CONSTITUTION:A graining device 13 is connected with a dust taking out pipe 12 of a first dust collecting device 5, and the graining device 13 is connected with the upper part of a fluidizing bed of a fluidized furnace (CBC) for burning unburnt carbon through a grained object transferring line 14. Coal cinders, a desulphurized reaction product and a desulphurized unreaction product in collected dust are solidifed respectively by absorbing water as crystal water throug adding water from a water supply pipe 15. They are thrown into the CBC for reburning. |
