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 manufacturer's nameplate.

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) m (1)

There is various type of heat losses in the boiler.. Some of them are:-Heat Loss Due to Unburnt Carbon. During the combustion process, most of the fuel gets burnt but some of the fuel particles remain unburnt and are deposited along with the ash..
