#### Boiler Capacity - Engineering ToolBox

Since the amount of steam delivered varies with temperature and pressure, a common expression of the boiler capacity is the heat transferred over time expressed as British Thermal Units per hour. A boilers capacity is usually expressed as kBtu/hour (1000 Btu/hour) and can be calculated as. W = (h g - h f…

→ boiler capacity =11,110 kW * 0.9 ~=10,000 kW. Why is boiler capacity given in ton per hour? It is sometimes difficult to understand boiler capacity terminology because not all manufacturers stick to norms when advertising boiler capacities. World over, the capacity of boilers is stated in terms of: 1.) square feet of heating surface.

Jul 17, 2017 · According to the standard calculation, it takes 288,000 Btu to melt a ton of ice in 24 hours, or 12,000 Btu per hour. Therefore, 12,000 Btu per hour equals one ton of cooling, Tip. Although window units are typically rated in Btu, heat pumps and central air conditioning systems are almost always rated in tonnage.

It is common to express the output of fire tube and water tube steam boilers in Boiler Horsepower, MBTU or in Pounds of Steam delivered per hour. W = (hg - hf) m where W = boiler capacity (Btu/h) hg = enthalpy steam (Btu/lb) hf = enthalpy condensate (Btu/lb) m = steam evaporated (lb/h) Calculate the boiler capacity for example:

How to Calculate Boiler Heat Input Rate. Depending on its energy source, a boiler may get its heat from the flow of electric current or from burning fuel. Each of these sources offer its own method for calculating the boiler's heat input rate. A separate method, however, works for all boilers. The boiler's
