SEWAGE SLUDGE INCINERATOR WITH GAS TURBINE

PROBLEM TO BE SOLVED: To establish a sewage sludge incineration system that effectively uses the exhaust gas of a gas turbine to reduce energy costs, by a method wherein the gas turbine is connected to a power generator and the exhaust gas of the gas turbine is directly fed into a sewage sludge incinerator as combustion air as it is. SOLUTION: The exhaust gas of a gas turbine 13 is directly fed into an incinerator 1 through a feed path 20 and used as combustion air as it is. Especially, in the case the incinerator 1 is of a fluidizing bed type, a portion of the exhaust gas of the gas turbine 13 is fed into the incinerator 1 as secondary air from points different in elevation. Thereby, the exhaust gas of the gas turbine 13 in a sewage treatment plant can be effectively utilized and a rational system with less energy costs and less count of auxiliary equipment can be established.
