Boiler Efficiency - an overview | ScienceDirect Topics
Boiler efficiency is a measure of how effectively chemical energy in fuel is converted into heat energy in steam going to the turbines. The largest boiler efficiency loss is sensible heat lost as hot flue gases (and ash) exit the boiler. Unburned carbon losses equate to the fraction of combustible fuel which is not burned in the boiler.Get Price

A boiler is a pressure vessel that is designed to generate heat, produce steam or cool gases. Typically built as a rectangular or cylindrical tube, the vessel is closed at both ends and is fully insulated. Fuels such as wood, coal, oil, or natural gas power the device, making it possible for pressures of 30 bar and more to be created inside.Get Price
