Thermal power is supplied by a fuel to a boiler. Boilers are used in power plants in order to produce high pressured steam, so that the plant can generate electricity. The process that does this is known as the Rankine cycle. The boiler takes in energy from some form of fuel such as coal, natural gas, or nuclear fuel to heat water into steam.
12/22/2016 · Chimney is just not a tall structure to shunt flue gas. Since it is the last stage where we can regulate the heat loss to environment, chimney’s shape and height can influence the efficiency of boiler [and hence Power Plant]. If weather and fanning is fine, the flue gas will shunt straight to high in sky, as you can see in the picture below.
The first part of the conversion is efficiency of the boiler and combustion. For this example we take 88 % on an HHV basis that is the normal range for a well-optimized power plant. Second part is the steam cycle efficiency. Modern Rankine cycle, adopted in coal fired power plants, have efficiencies that vary from 32 % to 42 %.
Stationary boilers are used for power plant steam, for central station utility power plants, for plant process steam etc. They will be stationary once erected in the site. Mobile boilers or portable boilers include locomotive type, and other small units for temporary use at sites. 7. Single Tube and Multi Tube Boiler
