Tenughat Vidyut Nigam Limited is a power generating company incorporated on 26.11.1989 of Jharkhand .
The project site known as Tenughat Thermal Power Station (TTPS) is located at village.Lalpania in Dist‐Bokaro. The project is situated on the bank of Tenughat reservior. . .
The total installed capacity of Tenughat Thermal Power Station is 420MW having two units of 210 MW capacity each.
The daily requirement of coal for full load generation from its 2x210 MW units is a approximately 7000 MTs which is met from coal mines of CCL situated in the vicinity of plant within 50 Kms..
TTPS has an acquired land of approx. 1800 acer

4-1:- isobaric heat supply(steam generator or boiler)
COAL:-
Plant needs 700 mt coal per day for the running of 2x210 mw plant
It is supply by coal block ccl which is 50 kmsaway from the plant
WATER:-
Plant get water from tenughat dam
Coal Handling Plant
• Wagon unloading system
• Crushing system
• Conveying system
Coal handling plant section
Unload the coal from wagon to hopper with the help of wagon Tripler.
Hopper allows to pass coal pieces ≤ 200mm
From hopper coal fall on vibrator which is supported by roller.
Belt are used to convey coal from coal handling plant to furnace.
Specification:-◦ Belt width : 1400mm◦ Speed : 2.2m/sec◦ Total install power : 360kw ◦ Capacity : 1350/750 ton/hr◦ No. of conveyor: 38
CRUSHER HOUSE:- It consists of crushers which are used to crush the coal to 20 mm size.
Two types
Primary crusher
oRail crusher
oRotary breaker

RIVERHOT WATER
It is a closed vessel in which water under pressure is converted into steam.
Hot water or steam used to transfer heat to a process.
A boiler is always designed to absorb maximum amount of heat released in process of combustion.
Furnace:- It is primary part of boiler where the fuel is burnt to liberate the heat energy.
