Method for adjusting atmosphere inside exhaust heat recovery boiler and exhaust heat recovery boiler

摘要

PROBLEM TO BE SOLVED: To provide an exhaust heat recovery boiler capable of preventing corrosion caused therein.;SOLUTION: There is provided an exhaust heat recovery boiler 1 comprising: a heat exchange part 11 into which exhaust gas of a gas turbine 2 driven by combustion gas is led to generate steam; and an air conditioning facility 13 which communicates with an exhaust gas flow channel F of the heat exchange part 11 where the exhaust gas passes. The air conditioning facility 13 includes a cooling part 133 which collects and cools the gas in the exhaust gas flow channel F, and a heating part 135 which heats the gas cooled by the cooling part 133 and returns the gas to the exhaust gas flow channel F.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2018,JPO&INPIT
