TRAINING AT TENUGHAT THERMAL POWER STATION

TRAINING AT TENUGHAT THERMAL POWER STATION Tenughat Thermal Power Station is a coal-based thermal power plant located at Maithon in Bokaro district in the Indian state of Jharkhand . The power plant is owned by Jharkhand State owned Tenughat Vidyut Nigam Limited. It has an installed capacity of 420 MW (2x210 MW). Keeping in view the availability of abundance source of water and coal from the adjacent coal mines, the Government of Bihar commissioned the Tenughat Thermal Power Project. The overall business of the power station is to produce power as per the made demand and transfer it to the grids installed at Bihar Shariff and Patratu through a 400 KV transmission line. The 30 day training programme was divided into various segments so as to have a crystal clear view of each and every department. They were as follows:- 1) Boiler and its auxiliary: This part forms the core of the power plant as the fuel i.e. the coal undergoes combustion inside the boiler after which, the water present in the water tubes gets converted into steam for further proceedings towards the turbine. The auxiliary includes PA (primary air) fan, FD (forced draught) fan, wall blowers etc which contribute towards the effective functioning of boiler. 2) Turbine and its auxiliary: This involves the section of the power plant which acts as a prime mover i.e. which provides work. The steam coming from the super-heaters finally enters the turbine thus rotating the machine which eventually rotates the generator thus producing power. I got to learn about the level of silica content maintained taking into account the safety of the turbine along with the minimization of moisture content. 3) Ash Handling Plant: This department involves the proper handling of ash, which is nothing but the residue left once the coal is burnt completely. The ash is taken out from the boiler via bottom ash hopper and economizer hopper, and finally gets transferred to the ash pond mixing it with ample amount of water. 4) Coal Handling Plant: This department caters to the fuel need of the power plant i.e. coal. It takes care of the transportation of coal from the point of unloading to the stacking area, which further gets transferred to the coal bunkers. I got to experience and understand the functioning of machines like Paddle Feeder, Rotary breaker, Travelling Tipper etc. 5) Control and Instrumentation: This department involves controlling and maintenance of all the performance measuring devices installed

Tenughat Thermal Power Station is a coal-based thermal power plant located at Maithon in Bokaro district in the Indian state of Jharkhand. The power plant is owned by Jharkhand State owned Tenughat Vidyut Nigam Limited.

Keeping in view the availability of abundance source of water and coal from the adjacent coal mines, the Government of Bihar commissioned the Tenughat Thermal Power Project. The overall business of the power station is to produce power as per the made demand and transfer it to the grids installed at Bihar Shariff and Patratu through a 400 KV transmission line.

Some of the devices are the turbidity measuring device, conductivity of water measuring device, pull cord and Zero sway switch(ZSS) used in conveyor belts etc.
LEARNINGS1) How to work together as a team in case of any mishap or crisis.2) Practical application of theoretical knowledge gained at the institution.3) Reason behind the design and material selection of machines and equipments such as 'Ball and tube' coal mill, Rotary breaker etc.4) Organization structure or hierarchy of the officials working.
