Oxygen corrosion in boiler feedwater systems can occur during start-up and shutdown and while the boiler system is on standby or in storage, if proper procedures are not followed. Systems must be stored properly to prevent corrosion damage, which can occur in a matter of hours in the absence of proper lay-up procedures.Get Price
Once the turbine has completed start-up procedures the isolation damper is opened and the bypass damper is closed, consequently redirecting flue gas flow through the HRSG. The hot flue gas heats boiler feed water to produce steam, which, once it has reached sufficient quality, is used to drive a steam turbine to produce more electricity.Get Price

The HRSG is a key component of a combined cycle power plant. Its role is to convert as much of the heat as possible from the exhaust gas of the gas turbine into steam for a steam turbine. The temperature of the exhaust gases from the steam turbine will be between 400°C and perhaps 650°C, low compared to the gases exiting the boiler of a coal-fired power plant.Get Price
