What Is Boiler Combustion? (with pictures)

Boiler combustion is the study of how fuels are burned in boilers that heat water for steam. There are many applications for steam boilers, including chemical process heating, steam heat for buildings and hot water, and steam to drive electrical turbine generators. Combustion is the reaction of fuels with oxygen in air to create heat that is used for steam production.

Boiler Operations & Boiler Maintenance | O&M | BetterBricks

Cycling a boiler on and off is very inefficient because there is a pre-ignition purge and a post-ignition purge that draw heat out of the boiler with each cycle. Also, in the case of a non-modulating boiler, cycling doesn't allow the boiler to operate at part load and steady firing rate when combustion efficiencies are at their best.
