Combustion Controls for Boilers | 2016-08-01 | Process Heating

Steam generated from boilers is used in many industrial processes, including manufacturing, refining, chemical processing and power generation. The burner is the heart of a boiler system, providing the necessary combustion of fossil fuels. Yet, if the burner is the heart, then the combustion controls — which manage air and fuel flow to the burner — are the brains of the boiler system.

Good combustion is very rapid, has a high flame temperature, and is very turbulent. Turbulence is a key factor in boiler furnace combustion. If the turbulence is high, the mixing of the oxygen and fuel will be good, therefore, combustion will occur very rapidly and the result will be a high flame temperature.
