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. Typical excess air to achieve the highest possible efficiency for some common fuels: 5 - 10% for natural gas. 5 - 20% for fuel oil.

The thermal efficiency of an aircraft turbofan engine is related to combustion efficiency.It is net output thrust power to total input fuel energy of the combustor.However, net heat effects on Boiler efficiency is a measure of the goodness of the chosen process and equipment to transfer combustion heat to the heat in steam. Boiler efficiency can be defined as the ratio of the useful heat output to the total energy input. Combustion efficiency and energy management is achieved through accurate and repeatable measurement of gases. By monitoring the air and fuel rates to burners, optimal air-to-fuel ratios are achieved, resulting in significant reductions in fuel gas cost, improved process efficiency, enhanced product quality, better yields, while simultaneously lowering combustibles.

With this understanding, suitable models for the combustor operation can be developed to relate, over the operating range, performance to inlet conditions. In the course of the experiments it is important to develop and verify Practical efficiency limits for open cycle engines are defined by factors such as: irreversible losses (combustion irreversibility, exergy lost with combustion products, exergy transferred with heat losses, etc.), work extraction efficiency, friction, material limits and cost. 2016-06-07 · The maximum exergetic efficiency of 55.12%, 53.19%, and 23.43% from deflagration combustion process and from detonation combustion process, 67.55%, 57.49%, and 24.89%, are obtained from aforesaid H 2 mass fraction.
