BOILER FOR POWER GENERATION, AND MANAGEMENT METHOD OF COMPOSITE FUEL FOR BOILER FOR POWER GENERATION

摘要

PROBLEM TO BE SOLVED: To provide a boiler for power generation capable of effectively preventing a state where an interior of composite fuel comprising coal and biomass etc. stored inside a fuel bunker becomes high temperature.;SOLUTION: The boiler 1 for power generation is composed of the fuel bunker 2 for storing the composite fuel; a crushing machine 3 for crushing the composite fuel; a combustion furnace 4 for burning the composite fuel; a cyclone 5 for recovering combustion ash; and a convection heat transfer means 6 for performing heat exchange between combustion gas and circulation water. A connecting pipe 7 for connecting the fuel bunker 2 with the crushing machine 3 is provided with a shielding means 9 comprising a shielding plate 10 for shielding inside of the connecting pipe 7 and a degassing hole 12 positioned below the shielding plate 10 to leak air inside the connecting pipe 7.;COPYRIGHT: (C)2010,JPO&INPIT
