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 reservoir.

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 acre

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

Conveying system

12

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.

GENERATOR

It converts mechanical power into electrical power.

PRINCIPLE- Electromechanical energy conversion

TECHNICAL SPECIFICATION- Active output - 110 MW Power factor – 0.85 lag Excitation voltage - 230 Volt Rated voltage – 11 KV Rated speed – 3000 rpm Phase connection – star-star

18

ELECTROSTATIC PRECIPATOR

Used for the removal of suspended particles and fly ash from industrial flue gases PRINCIPLE- Produces an electrostatic field which attracts the ionized carbon particles and other such particulates which cause environmental pollution.

CONCLUSION:

The first stage of training is quite fruitful and knowledgeable.we see lots of heavy machines like generator,turbine,wagon trippler e.t.c. we also see switchyard which makes us know about transmission and distribution and various connections.The architecture of powerplant make us to realise that it is not only to learn about machine and its structure but the great part is how to maintain and manage it and without proper planning it is not possible. Basically during this period we learn everything about management and operation of power plant.
