What is Boiler Blowdown? Text Only - Industrial steam

2021-2-6 · Operation of Continuous Blowdown Heat Recovery – The blowdown heat recovery system operates at the deaerator pressure. the surface blowdown water enters the flash tank. The water temperature is reduced to 227oF (5 psig) and it falls to the storage tank. The flash steam is vented to the deaerator to be used to heat the boiler feedwater.
