CONCLUSION:-
After visit at the Wanakbori Thermal Power Station I can say
that one can visualize the complex study of power generation using coalas a fuel, which will help me a lot in future in many field & I can
understand the function of each component in thermal power station, their
importance, their arrangement & precautions that to be used for the safety
in the plant.
At last I will only say that I really enjoyed my visit over hereand I again want to thank all my faculties, staff of Wanakbori Thermal
Power Station to give me this great pleasure of the training.
