When coalmines are very close to power plant (5 to 10 km) and power plant capacity is lesser than 1000 MW, aerial ropeway is considered to be most economical and convenient means of coal transport. Coal transport by truck is quite common for use in industrial boilers and small power plants of up to 200 MW capacities.
Thermal Power Plant is an electric producing power plant in which fuel (such as coal, liquefied fuel, uranium, and natural resources) is used to generate heat and that heat is further utilized to heat the water to make steam and that steam is used to rotate the turbine and further electricity generates with the help of 3 phase supply generator. ...
Mechanized ash handling systems developed as the size of coal fired boilers increased beyond the sizes permitting manual handling of large quantity of ash.

Thermal efficiency is defined as the ratio of heat equivalent mechanical energy available at the turbine to the heat energy available at the combustion of coal in the boiler. The thermal efficiency of the thermal power plants is 30% approx. Most of the heat energy (approx. 50%) is wasted in the condenser.
Simple and sound, requiring minimum operations and transportation. 2. No double handling of coal in plant. 3. Handling unit should be centralized to facilitate inspection and maintenance. 4. Electric motors can be used as driver of mechanism. 5. Working parts should be enclosed to avoid abrasion and corrosion.
The thermal power plant also called a thermal power station finds use to convert heat energy to electric power for and commercial applications. In the process of electric power generation, steam-operated turbines convert heat into mechanical power and eventually into electric power. The thermal power plant, also known as a …
For a typical 2 × 660 MW plant capacities with Indian coal quality that consists of high ash content, the total makeup water requirement for ash handling plant is estimated in the following range. Table 3.1 shows that ash handling plant consumes 1.3–1.5 m 3 of water for production of 1 MWh
