17/3/2015 · Step 1: Determine Properties of Steam Produced. Using the Steam Property Calculator, properties are determined using Steam Pressure and the selected second parameter (Temperature, Specific Enthalpy, Specific Entropy, or Quality). The Specific Enthalpy is then multiplied by the Mass Flow to get the Energy Flow

General Boiler Information. 1 boiler horse power is about 42,000 BTUs of INPUT. 1 pound of steam is about 1,200 BTUs of INPUT fuel, and about 1,000 BTUs at the point of use, depending on the pressure of the steam. Low pressure steam is considered to be up to 15 psi; high is generally 100 psi and higher.

one pound of boiler feed water from say F. to 212° F. requires approximately 212 ---- 67 = 145 B.T.U.'s. The Heat of Vaporization of Steam. In raising the temperature of one pound of water from F. to F., 145 B.T.U.'s are required, but after a temperature of F. is reached we can impart heat to the water until it is all changed into steam with

Because a steam boiler makes heat by producing steam - by boiling water, at sea level, the temperature at the boiler will be boiling or 212 F or close to that figure. The actual steam boiler temperature may be a bit lower at high elevations above sea level, and the steam boiler temperature will be a bit higher than 212 °F for boilers operating at slightly higher pressures, as we'll illustrate in a table below.
