Combustion Of Fuel In Steam Boiler

Combustion is the process of igniting and burning a fuel source. As the fuel source burns it releases energy in the form of heat which can then be used to transform water into steam. Combustion is needed to power the boilers. The combustion system of the boiler and how efficiently it works, is at the core of operating an efficient boiler.

18/1/2018 · Combustion in Boilers There are four important factors that control combustion in boiler furnace: 1. Air supply- Need adequate air for complete combustion. The rating (capacity) of a boiler can be increased by supplying additional air (think of the effect of bellows on a small fire). Too much air can result in excessive stack losses.
