Combustion Air Pre-Heater
Combustion air pre-heater technology on large coal-fired boilers dates back to the early 1900's, and is used on most all large boilers todays. With the increasing price of fuel and technology improvements, the size of a boiler that can be economically equipped with a pre-heater should become smaller.

Combustion Analysis Basics
Combustion occurs when fossil fuels, such as natural gas, fuel oil, coal or gasoline, react with oxygen in the air to produce heat. The heat from burning fossil fuels is used for industrial processes, environ-mental heating or to expand gases in a cylinder and push a piston. Boilers, furnaces and engines are important users of fossil fuels.

Combustion efficiency
The combustion efficiency increases starting from the full load until roughly 35% partial load with a boiler system. The excess air and therefore the CO 2 content measured in the dry flue gas increases only slightly while the flue gas temperature falls due to more efficient utilisation of the heating surface in the boiler. At a partial load of <35% the greater …

Combustion and heating
Combustion and heating. The purpose of the combustion system is to turn the carbon, hydrogen and possibly sulphur in the fuel completely into CO 2, H 2 O and SO 2. So that combustion is as clean as possible, the correct mixture ratio of fuel and combustion air must be present at the right time and place in the combustion chamber.
