boiler water holding capacity calculation

How to calculate the capacity of a water tube boiler tha

Jan 16, 2018· Lets assume we bring in water at 60F (15.5C) which has a liquid enthalpy of 28 btus/lb. So we have to put in about 1153 btus to make 1 pound of steam. But of course we havent figured in boiler efficiency yet. A wood boiler is about 70% efficient. A bark & chip boiler is about 75% efficient.

Steam Calculators: Boiler Calculat

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.

Water Heating Calculator for Time, Energy, and Pow

How do I calculate btu size for heating a swimming pool? Im looking at a 50,000 btu boiler with a heat exchanger to heat a 33,000 gallon pool to 90 degrees f. Ive run then calculation through the formula above, and its coming up with a 600,000 btu boiler to raise the water temp (68f) in 5 hours to 90f, which seems to be a really high number?
