Along the West Coast there are nearly wood fired boilers. today for every thermal power plant. The combustion in pulverised coal fired boiler is affected by quality of coal, pulverised coal fineness, burner tilting angle, air fuel ratio, and slagging and NO x formation.

The review on different optimization techniques has been carried out. Wood fuels can basically be combusted using a stoker, grate combustion, or fluidised bed combustion.

Stoker burners are more common in farmhouses and are suitable for the small scale burning of mainly wood chips. Grate combustion is used in small and medium sized heat plants, whilst fluidised beds are used in larger scale Size: 1MB. Therefore, during combustion in grate boilers hard coal passes through three phases: drying, degassing and burn-out of the produced coke.

In the first section of a grate, coal is heated up by absorbing heat from the combustion chamber walls, already burning coal and air passing through the coal layer on a by: 2.

combustion gases pass through the boiler. The combustion chamber is taken, as the first pass after which there may be one, two or three sets of fire-tubes.

The most common boiler of this class is a three-pass unit with two sets of fire-tubes and with the exhaust gases exiting through the rear of the boiler. Stoker Fired Boiler.
