Coal power station dimensions are measured by their capacity. Using this criterion, the largest would be the Kendal Power Station in Mpumalanga, South Africa. It has a capacity of 4,116 Megawatt. Power is produced through half a dozen 686 MW units. The Turbine Maximum Continuous Rating is 16.67%.
How Does a Coal Power Station Function?
It starts when the coal is set at the burning room. This is at the plant’s bottom. The coal is lit and burned. When the coal is burned, more coal is added until electricity is generated.
When there is a high demand for electricity, coal will be burned nonstop. During nonpeak hours, it may not be necessary to burn coal nonstop.
Steam and Water Tank
As the fire buns, it heats up the water tank in the coal plant. The water is transformed into steam when it boils over. This steam will pass through a complex piping system. The debris and smoke within the plant will go up to the plant’s smokestack.
Regardless of the coal power station dimensions, their smokestacks include scrubbers or cleaning tools. These cleaning tools remove most of the CO2 and air pollutants. These chemicals are produced when the coal is burning. The smoke is released after it has been filtered by the cleaning tools.
The steam that goes through the pipes gets high pressure because the pipes decrease in size. This steam is hurled at a spinning turbine. The turbine is linked to a generator using rods.
When the generator turns, a couple of magnets cross over the wires to make electricity. The electricity passes the generator and goes to the power transmission lines. This is sent to the power grid.
The Rotary Atomizer
The rotary atomizer is part of the dry flue gas desulfurization system. This is used to remove the pollutants in the coal. In particular, the atomizers are used to remove sulfur dioxides. The atomizer takes the liquid and sprinkles it while making high speed turns.
With an FGD system, the liquid drawn into the atomizer is a mixture of water and lime. By atomizing the liquid, sulfur is taken out of flue gas. The gas gets in touch with droplets. The result is a powder. This is made up of the unwanted elements in the sulfur.
The coal power station dimensions can be subject to change. Of all the specs, it is the capacity that may be altered the most. The antipollution features are also being improved.
