STEAM TURBINE OPERATION METHOD OF EXHAUST GAS TREATING SYSTEM IN WASTE TREATMENT FACILITY

摘要

PROBLEM TO BE SOLVED: To prevent reduction of a power generation amount of a steam turbine due to an increase of an exhaust gas pressure of the steam turbine, in a steam turbine system of an exhaust gas treating system in a waste treatment facility. SOLUTION: In the steam turbine system, power generation of a steam generated from a waste heat recovery boiler 1 of the exhaust gas treating system in the waste treatment facility is performed by the steam turbine 3, and condensation is performed by a low pressure steam condenser 8. When a steam turbine exhaust pressure is increased to a set pressure or higher, a steam turbine inlet pressure is increased to thereby prevent reduction of the power generation amount.
