Epc of Thermal Power Plant
ENGINEERING, PROCUREMENT AND CONSTRUCTION PROJECT OF THERMAL POWER PLANT
Company mission:
To develop, implement innovative construction and on site implementation methods to meet the best industrial standards and to continuously improve on cycle time reduction and modernization of construction methods applicable for the power, process and infrastructure industries.
MAIN PLANT AREAS a) Bunker bay b) Turbine generator bay
Bunker Bay
Coal bunker
These are in ‘process storage silos used for storing crushed coal from the coal handling system. Generally, these are made up of welded steel plates.’ Normally, there are six such bunkers supplying coal of the corresponding mills. These are located on top of the mills so as to aid in gravity feeding of coal.
Coal feeders
Each mill is provided with a drag link chain/rotary/gravimetric feeder to transport raw coal from the bunker to the inlet chute, leading to mill at a desired rate.
Mills
There are six mill (25% capacity each), for every 200 MW unit, located adjacent to the furnace at “0” M lever. These mills pulverize coal to the desired fineness to be fed to the furnace for combustion.
Boiler
Air pre-heater
Air pre-heater transfer heat from flue gases to cold primary and/or secondary air by means of rotating heating surface elements. Beneath these regenerative type air pre-heaters, there exists a steam coil air pre-heater. These are located in the secondary pass of the furnace at a height of around ‘16’ M level. Each 200 MW unit is provided with two such air pre-heaters.
P. A. fan
The primary air fans (2 per unit- 50% capacity each) are designed for handling atmospheric air upto a temperature of 50 deg C. these fans are located at *0’ M level near the boiler.
F. D. fan
The forced draft fans (2 per unit – 50% capacity each) are designed for handling secondary air for the boiler. These fans are located at ‘0’ M level near the PA fan
ID fans
There are two induced
