Boiler Efficiency and Combustion

Pressure from legislation regarding pollution, and from boiler users regarding economy, plus the power of the microchip have considerably advanced the design of both boiler combustion chambers and burners. Modern boilers with the latest burners may have: Re-circulated flue gases to ensure optimum combustion, with minimum excess air.

Boiler Combustion |

One technology that offsets the efficiency loss due to lower flame temperatures in a firetube boiler is flue gas recirculation. Although the loss of radiant heat transfer could result in an efficiency loss, the recirculated flue gases increase the mass flow through the boiler – thus the convective heat transfer in the tube passes increases.

The energy generated from the incineration of solid wastes can be recovered as thermal energy, which is released from the flue gases exiting the combustion unit. Typically, the flue gases in WTE units are projected to range from 1,598 to 1,796°F (870 to 980°C) passing through the waste heat boiler downstream of the secondary combustion

Flue gases are the general name given to the mixed composition gases that are the by-product of a combustion process. A flue is typically a large pipe, duct, stack, chimney or other venting attached to a process system such as a boiler, furnace, steam generator, oven, etc. through which waste flue gases are exhausted from the combustion process.
