WebOct 17, 2024 · The standard blowdown amount to account for is a 4″ level drop in the steam drum. Madden blowoff vessel calculation sheets estimate the time it would take to achieve a 4″ level drop per your boiler steam drum dimensions, operating pressure, and blowdown line size. On average this is around 60 seconds. WebJul 24, 2024 · The fire case blowdown mostly governs the peak load and determines the …
