Boiler Formulas. Factor of Evaporation Water enters the boiler at 225°F. The boiler pressure is 100 psi and the boiler water temperature is 338°F. The latent heat is 881 Btu. What is the factor of evaporation? FE = SH + LH / 970.3.
When steam condenses on the wall of an exposed/uninsulated steam pipe, it gives up its enthalpy of evaporation. Proper utilization of steam helps in saving in the input cost of water and coal. Saving of each kg of steam is directly proportional to the saving of some percentage of water, coal and electricity.
The factor relating these rates is the specific heat capacity of water. Subtract the water's initial temperature from its temperature at the end of the period whose input rate you are calculating. For example, if the water in the boiler rises from 20 to 50 degrees Celsius, subtracting 20 from 50 gives 30 degrees.
