THERMAL POWER PLANT PARALI
This document provides information about the Parali Thermal Power Station located in Beed district, Maharashtra, India. It has a total installed capacity of 1130 MW across 6 units built between 1971-2005. Key components of the power plant include the coal handling plant, water handling plant, boiler system, turbine, generator, and transformer. Coal is used as the primary fuel source due to its relatively low cost compared to other fuels. The document describes the basic processes of energy conversion from coal to electricity at the thermal power station.

- 10. WHY COAL asFuel ? Coal can provide usable energy at a cost of between 12 to 15 % compared to oil and natural gas, and coal prices are relatively stable. Coal is inherently higher-polluting and more carbon-intensive than other energy alternatives. However, coal is so inexpensive that one can spend quite a bit on pollution control, and still maintain coal’s competitive position.

STRUCTURE OF BOILERS Boilerstructure is supported on 4 columns that is hung from top and supported on vertical columns All plates, rivets, bars and their testing is covered under regulation and construction is done under the supervision of inspecting officer at all the stages The boiler is a rectangular furnace about 50 feet(15 m) on a side and 130 feet (40 m) tall. Its walls are made of a web of high pressure steel tubes about 2.3 inches (58 mm) in diameter. Pulverized coal is air-blown into the furnace through burners located at the four corners, or along one wall, or two opposite walls, and it is ignited to rapidly burn, forming a large fireball at the center
