Title:
WATER CONDENSATING AND FEEDING DEVICE FOR BOILER AND TURBIN
Document Type and Number:
Japanese Patent JP3276247
Kind Code:
B2
Abstract:
PURPOSE: To recover heat from exhaust gas emitted from the outlet of a gas turbine and improve plant efficiency in a gas/steam turbine complex plant.
CONSTITUTION: A deaerator 7 is provided upstream with low pressure SGC6 for recovering a low pressure waste heat and heating feedwater to recover the waste heat from a gas turbine. At this time, in order to prevent the low pressure SGC6 from the acid corrosion caused by the evolution of S content from the exhaust gas due to the lowering of the inlet temperature of the low pressure SGC6 at the start of the operation or at a low load, a part of the feedwater at the outlet of the deaerator 7 is sent back upstream of the low pressure SGC6 to raise the condensation temperature.
