Combustion optimization in PF Boilers

CO is a direct measure of the completeness of combustion, unaffected by air infiltration, optimum boiler efficiency :when the losses due to incomplete combustion equal the effects of excess air heat loss. Theoretically, CO should be zero whenever there is oxygen in the flue gas. Maximum boiler efficiency when the CO is between 100 and 400 ppm.

Combustion Air: What Is It? Why Is It Important? - Home

Combustion Air (1) Air that is supplied to combustion appliances to be used in the combustion of fuels and the process of venting combustion gases. Inadequate combustion air can lead to dangerous problems. (2) The duct work installed to bring fresh, outside air to the furnace and/or hot water heater.

Boiler Efficiency | Kane International Limited

Boiler Efficiency. The objective of a boiler is to burn the hydrogen contained in the fuel with oxygen from the atmosphere to produce heat. Combustion efficiency analysers exploit the fact that by knowing the fuel (and its chemical composition) and measuring the flue gas temperature and either the oxygen or carbon dioxide level the efficiency of the boiler can be calculated.
