Boiler Ratings | Spirax Sarco

Shell boilers are often operated with feedwater temperatures lower than 100°C. Consequently the boiler is required to supply enthalpy to bring the water up to boiling point. Most boilers operate at pressures higher than atmospheric because steam at an elevated pressure carries more heat energy than does steam

Steam Calculators: Boiler Calculator - Energy

Mar 17 2015 · 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.

Steam Calculators: Boiler Calculator - Energy

Step 4: Determine Boiler Energy. Boiler Energy = Steam Energy Flow + Blowdown Energy Flow - Feedwater Energy Flow [ Boiler Energy (Flow) = 95977 = 115903 + 3708 - 23633 ] Step 5: Determine Fuel Energy. Fuel Energy = Boiler Energy / Combustion Efficiency [ Fuel Energy = 144981 = 95977 /
