OPERATING METHOD FOR WASTE DISPOSAL FACILITY WITH POWER GENERATION FACILITY

摘要

PROBLEM TO BE SOLVED: To increase electric power generation while suppressing annual total electric power generation by carrying out efficient operation by a plurality of furnaces, and to carry out power generation even when an annual disposal amount or a heating value of waste is small.;SOLUTION: In the waste disposal facility with a power generation facility composed of a plurality of furnaces, waste is incinerated, pyrolyzed, or melted by a plurality of waste disposal furnaces, combustion exhaust gas is guided from each waste disposal furnace 1 to a boiler 2 to generate steam, the generated steam is superheated by a superheater 10 to produce superheated steam, and the superheated steam is guided to the power generation facility 13 comprising a common steam turbine 11, and a generator 12 to carry out power generation. An operation load of each waste disposal furnace 1 is lowered than rated operation, partial load operation of each waste disposal furnace 1 is carried out in response to a disposal amount of waste, operation days by the plurality of plural furnaces is increased, and electric power generation is increased.;COPYRIGHT: (C)2009,JPO&INPIT
