Blowdown Heat Recovery – Industrial Steel & Boiler Service

Blowdown heat recovery systems can recover about 90% of the blowdown thermal value. The value varies with volume, boiler pressure, method/frequency of blowdown and fuel cost. Continuous blowdown systems use 5 – 10% boiler capacity. Therefore, if estimating a value, 5% of average boiler capacity is reasonable. The blowdown BTU value varies
