Combustion efficiency is dependent upon using the right amount of air to consume the fuel. In fuel-fired process heating, the largest source of energy loss is through the exhaust stack, which is why managing air flow is essential to combustion efficiency. When fuel burns in the presence of oxygen it is converted to carbon dioxide, water and heat.
Combustion efficiency is a measure of how efficiently the heat content of a fuel is transported into valuable heat. The stack temperature and flue gas oxygen combinations are primary symbols of combustion efficiency. The combustion efficiency of a boiler signifies the burner’s capacity to burn fuel.
2018-8-5 · to achieve ideal combustion and prevent combustion problems associated with too little excess air, while not providing too much excess air to reduce boiler efficiency. Research has shown that 15% excess air is the optimal amount of excess air to introduce into the boiler combustion process.
Before we get to our efficiency tips, we need to understand boiler efficiency. The majority of heat is lost from your boiler in the stack or boiler water. The goal is to create conditions that generate the smallest possible amount of flue gas (exhaust gas that is expelled) at the lowest possible temperature.
A periodic boiler flue-gas analysis is the best indicator that an adequate supply of combustion air exists. This, and any necessary burner adjustments, should be performed by a trained technician with the proper equipment to measure the amount of excess oxygen and/or carbon dioxide and ppm of carbon monoxide.

Combustion efficiency; Thermal efficiency; Apart from these efficiencies, there are some other losses which also play a role while deciding the boiler efficiency and hence need to be considered while calculating the boiler efficiency. Combustion Efficiency. The combustion efficiency of a boiler is the indication of burner’s ability to burn fuel.
When the temperature is less than 50–60 °C, the efficiency rapidly increases because the water in the exhaust gas is condensed and the boiler uses the latent heat generated by the condensed water. Assuming an operating air ratio of 1.4 for the boiler, the temperature of the exhaust gas for a condensing boiler should be less than 53 °C.
Boiler Combustion Efficiency. Combustion boiler efficiency generally describes the ability of a burner to burn the entire fuel into the boiler combustion chamber (furnace). The efficiency of this type is calculated from the amount of fuel that does not burn along with the amount of air combustion air (air excess).
