Steam Calculators: Boiler Calculator

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.

3. STEAM SYSTEM - Bureau of Energy Efficiency

3. Steam System Bureau of Energy Efficiency 56 When the steam condenses back into water, it gives up its enthalpy of evaporation, which it had acquired on changing from water to steam. The enthalpy of evaporation is measured in kCal/kg. Its symbol is h fg. Enthalpy of evaporation is also known as latent heat. The temperature at which water

Industrial Knowledge: Boiler Rating

Boiler evaporation rate = 1 800 kg/h Some manufacturers will give a boiler rating in kW. This is not an evaporation rate, and is subject to the same 'from and at' factor. To establish the actual evaporation by mass, it is first necessary to know the temperature of the feedwater and the pressure of the steam produced, in order to establish how

Boiler (power generation) - Wikipedia

A boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7–2,000 kPa or 1–290 psi) but, at pressures above this, it is more usual to speak of a steam generator.

Rate of evaporation and steam tables Physics Forums

Looking at the steam table below, if I understand things correctly, it will take 419kJ to bring a kg of water to the boil at 100°C and a further 2257kJ to turn all of that boiling water into steam. I assume that would have to be in an open boiler, as the pressure inside of a closed vessel would

How to Calculate Boiler Steam Flows Hunker

Use boiler horsepower to calculate steam flow. Boiler horsepower is not related to mechanical horsepower. It is a boiler industry rating that predicates the amount of saturated steam a boiler will generate starting with water at 212 degrees Fahrenheit and 0 pounds per square inch gauge (psig--meaning atmospheric pressure) and ending with steam at 212 F and 0 psig.
