2019-10-4 · Boiler efficiency may be indicated by. Combustion Efficiency - indicates a burners ability to burn fuel measured by unburned fuel and excess air in the exhaust; Thermal Efficiency - indicates the heat exchangers effectiveness to transfer heat from the combustion process to the water or steam in the boiler, exclusive radiation and convection losses; Fuel to Fluid Efficiency - indicates the
2019-9-23 · If the vapor then condenses to a liquid on a surface, then the vapor's latent energy absorbed during evaporation is released as the liquid's sensible heat onto the surface. The large value of the enthalpy of condensation of water vapor is the reason that steam is a far more effective heating medium than boiling water, and is more hazardous.

2013-2-16 · This is considered equivalent to the evaporation of 341 pounds per hour from and at 212° F. A boiler horse-power is equivalent to 33,327 B. T. U. per hour. As all boilers do not generate steam at the same pressure and from the same temperature of feed-water, it is necessary to reduce the actual evaporation to an equivalent evaporation.
