Optimal Combustion Process - Fuels and Excess Air

2020-3-20 · Natural gas-fired boilers may run as low as 5 percent excess air. Pulverized coal-fired boilers may run with 20 percent excess air. To determine the excess air at which the combustion system will operate we have to start with the stoichiometric air-fuel ratio known as the perfect or ideal Optimal Combustion Process - Fuels and Excess

calculation of the excess air of combustion process

Calculation of the Excess Air of Combustion Process

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.
