Boiler - Wikipedia
2019-10-13 · A fuel-heated boiler must provide air to oxidize its fuel. Early boilers provided this stream of air, or draught, through the natural action of convection in a chimney connected to the exhaust of the combustion chamber. Since the heated flue gas is less dense than the ambient air surrounding the boiler, the flue gas rises in the chimney

Working Principle Boilers Guide
Both gas and oil fired boilers use controlled combustion of the fuel to heat water. The key boiler components involved in this process are the burner, combustion chamber, heat exchanger, and controls. The burner mixes the fuel and oxygen together and, with the assistance of an ignition device, provides a platform for combustion.

Boiler Fuel - an overview ScienceDirect Topics
Fuel reburning involves diverting 10–20% of a boiler's fuel input to create a secondary combustion zone downstream of the primary zone. In the secondary or reburn zone, NO x from the primary zone is reduced to elemental N 2. Additional air is added higher up in the furnace to complete the combustion.
