Steam Calculators: Boiler Calculator

Steam, Boiler, and Blowdown Pressure are the same. Combustion Efficiency is the % of fuel energy that is directly added to the feedwater and not otherwise lost or used. Blowdown Rate is the % of incoming feedwater mass flow rate that leaves the boiler as a saturated liquid at boiler pressure.

I am designing a hot water loop for an industrial process and have a question about gas pressure requirements. Most boilers give a minimum gas pressure requirement of ~4-5"w.c. but this value is static pressure. What I want to know is the dynamic pressure requirement. IE, what the boiler inlet pressure needs to be when gas is flowing.

Fuel Firing Apparatus - National Board of Boiler and Pressure

Gas pressure regulator (PRV) - the purpose is to maintain the pilot fuel at a constant pressure as recommended by the burner manufacturer. Safety shut-off valve (SSOV) - automatically opens and shuts off fuel supply to the pilot burner. Testing of the fuel firing apparatus, including the flame safeguard system, is relatively easy.
