Boiler Efficiency and Combustion | Spirax Sar

To ensure complete combustion, an amount of ‘excess air’ needs to be provided. This has an effect on boiler efficiency. The control of the air/fuel mixture ratio on many existing smaller boiler plants is ‘open loop’. That is, the burner will have a series of cams and levers that have been calibrated to provide specific amounts of air

Combustion Efficiency and Excess Air - Engineering

: 364KB2020-5-8 · 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. Carbon dioxide - CO2 - is a combustion

: 305KB: 98KBOptimizing boiler and steam system efficiency is more important than ever. Although a boiler’s efficiency is primarily a result of its design, an operator can maintain or significantly improve efficiency by effectively managing various techniques and key functions. Read Part 2 of this two-part series which discusses key operation functions.

Air Fuel Ratio Effect on Combustion Efficien

Air Fuel Ratio Effect on Combustion Efficien

Air Fuel Ratio and Excess Air 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.

Calculation of the Excess Air of Combustion Proces

Calculation of the Excess Air of Combustion Proces

Determining the amount of excess air in the boiler burning process depends on several main factors such as fuel type, boiler design, burner design, and boiler load. Generally, coal fired boilers use excess air as much as 15% to 30%. For boilers with gas or petroleum as its fuel, requires less excess amount of water.
