Air–fuel ratio - Wikipedia
2019-6-14 · Air–fuel ratio (AFR) is the mass ratio of air to a solid, liquid, or gaseous fuel present in a combustion process. The combustion may take place in a controlled manner such as in an internal combustion engine or industrial furnace, or may result in an explosion (e.g., a dust explosion, gas or vapour explosion or in a thermobaric weapon). The

Combustion Efficiency and Excess Air - Engineering
2019-6-14 · The combustion efficiency increases with increased excess air - until the heat loss in the excess air is larger than the heat provided by more efficient combustion. Excess air to achieve highest possible efficiency for some common fuels: 5 - 10% for natural gas; 5 - 20% for fuel oil; 15 - 60% for coal

Reasons for Increasing Exhaust Gas Temperature of
The air leakage coefficient is too large. Air leakage in the furnace and shaft flue of negative pressure boiler is unavoidable, and the air leakage coefficient allowed by a certain heating surface is stipulated. When the air leakage coefficient increases, the influence on exhaust gas temperature is similar to that of superheated air coefficient.
