What Is Combustion Efficiency?

Combustion efficiency and combustion chamber efficiency. It is the ratio of the amount of heat that can actually be used to heat the combustion products when the quantitative fuel is burned in the combustion chamber to the low-level calorific value released when the fuel achieves complete combustion under adiabatic conditions. It is the main index to evaluate the operation uniformity of various combustion chambers (or boiler grate). ^[1]

Combustion efficiency mainly depends on the characteristics of the combustion device and the fuel itself, and is related to factors such as the environment. The index of combustion efficiency is meaningful relative to a certain combustion device and a certain fuel, that is, an index for evaluating a specific combustion device to burn a specific fuel. This indicator is often different in the following situations: specific combustion devices when burning different fuels; specific fuels when burning in different combustion devices.

Combustion efficiency, also known as embers rate, burn rate. Burning efficiency is used in traditional textbooks and was born relatively early. Nowadays, the application of the embers rate is more extensive because this expression is more intuitive and directly expresses the proportion of the burned materials to ash through the combustion of a specific combustion device, which is widely used by those in the industry.
