How Is A Boilers Kilowatt (kW) Rating Determined? | Experts123

Apr 26, 2017 · The amount of heating surface determines the kilowatt rating of a boiler. Calculate the kilowatt rating by multiplying the heating surface in square metres (m2) by 10. 1 m2 of heating surface = 10 kW. (10 m2 = 100 kW, 100 m2 = 1000 kW, etc.) Go To Top How Do I Find The Heating Surface Of My Boiler? Check the manufacturers nameplate.

How to Calculate Boiler Steam Flows | Hunker

Use btu/hr (British thermal units/hour) heat input rate to calculate boiler steam flow. It takes 970.28 btu/hr to produce 1 pound of steam at the above conditions. If 50 million btu/hr are being applied to the boiler, divide by the 970.28-btu/lb to yield 51,531-lb/hr steam flow. This is an average industrial boiler.
