Steam Turbine Power Plant. Steam power plants burn fossil fuel in the furnace of a steam boiler. Steam from the boiler expands through a steam turbine, which is connected to a drive shaft of an electric generator. The exhaust vapor expelled from the turbine condenses, and the liquid is pumped back to the boiler to repeat the cycle.

Jul 01, 2017 · To improve Boiler efficiency, coal must burn out. Incomplete combustion in mark with still remaining coal combustion on the back of the furnace.
Windboxes. The overall performance of a power plant depends significantly on how fuel and combustion air enter the furnace. Large fossil fuel boilers can have up to 100 individual burners that inject fuel and air. The proportion of flow through each of these plays an important role in the efficiency of the combustion process.
fuels are used to reduce emissions or improve boiler performance. Fuels commonly fired in boilers include fossil, biomass, and RDFs as well as other types of fuels and fuel combinations. Coal, petroleum-based oils, and natural gas are fossil fuels commonly fired in ICI boilers. However, other forms of solid, liquid, or gaseous fuel derived from these fossil fuels are sometimes included in this category.
Coal also is the most used fossil fuels for producing electricity as we use coal power plant for producing around 40% of the world’s electricity, and we commonly use it in cement manufacturing and industrial purposes such as refining metals.
