AP-42 Section 1.6 Wood Residue Combustion in Boilers

This type of boiler has a fast response to load changes, has improved combustion control, and can be operated with multiple fuels. Natural gas, oil, and/or coal, are often fired in spreader stoker boilers as auxiliary fuels. The fossil fuels are fired to maintain constant steam production when the wood residue

Coal fired boiler - Guideline for energy efficient

Higher oxygen level means excess air, Excess air in flue gas takes away heat along with flue gases. Improper air supply: Carbon monoxide generation in flue gas indicated improper combustion of fuel and it must be avoided. Fuel used in the boiler should be combusted completely to get complete heat of fuel.

Internal Recirculation Circulating Fluidized-Bed Boilers

problems in CFB boilers due to the high solids loading in the flue gas. The severity of this erosion is exponentially related to the velocity of the flue gas through the system. On hot-cyclone CFBs the particle separator depends upon an extremely high flue gas velocity to provide the energy needed to efficiently

Fluidized bed combustion boilers

Fluidizing velocity in this type of boiler is relatively very high 3.7-9m/sec, The combustion takes place at 840-900 °C, and the fine particles (<450 microns) are elutriated out of the furnace with flue gas velocity of 4–6 m/s. The particles are then collected by the solids separators and circulated back into the furnace.

Flue-gas stack - Wikipedia

A flue-gas stack, also known as a smoke stack, chimney stack or simply as a stack, is a type of chimney, a vertical pipe, channel or similar structure through which combustion product gases called flue gases are exhausted to the outside air. Flue gases are produced when coal, oil, natural gas, wood or any other fuel is combusted in an industrial furnace, a power plant's steam-generating boiler
