Combustion Efficiency and Excess Air – Engineering
2019-11-15 · Carbon dioxide – CO 2 – is a combustion product and the content of CO 2 in a flue gas is an important indication of the combustion efficiency. Optimal content of carbon dioxide – CO 2 – after combustion is approximately 10% for natural gas and approximately 13% for lighter oils.
Combustion Efficiency Optimization Manual for
Pre-tuning adjustment bygt;an experienced boiler operator will minimize the number of changes necessary during subsequent tuning and testing. The pre-tuning inspection of combustion conditions should include checks to ensure that: 0 The flame does not impinge on any heat transfer surfaces.
Combustion optimization in PF Boilers
2013-11-27 · 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.
