The Efficiency of a Pulsed Detonation Combustor-Axial


Investigation of Emission Characteristics for Diluted Flames

2021-02-10 · Combustion efficiency is a measure of how efficiently a device consumes fuel. Ideally, it would be measured at 100%, meaning that the fuel was completely consumed. In practice, this level of efficiency is impossible to achieve, but it's possible to come close. The combustor then heats this air at constant pressure. After heating, air passes from the combustor through the nozzle guide vanes to the turbine. In the case of a ramjet or scramjet engines, the air is directly fed to the nozzle. A combustor must contain and maintain stable combustion despite very high air flow rates.

Combustion efficiency is a measurement of how well the fuel being burned is being utilized in the combustion process. This is different from the efficiency number produced on the analyzer, which is reflective of the total amount of heat available from the fuel minus the losses from the gasses going up the stack. Stack loss is a measure of the heat carried away by dry flue gases and the moisture loss.

The flame instabilization occurs due to less resident time of air which tends to affect the output efficiency and it leads to loss of fuel energy. combustor efficiency is very rare in the literature. 128 Int. J. of Thermodynamics, Vol. 8 (No. 3) tcccdcrccrd h =εh +(1 - ε)h +εh +(1 - ε)h co Figure 1. The scheme of the CFB combustor. 2015-05-05 · All jet engines have a combustor or burner in which the air and fuel are mixed and burned. The burning occurs at a higher pressure than free stream because of the action of the compressor.
