CONCLUSION:-
After visit at the Wanakbori Thermal Power Station I can say that one can visualize the complex
study of power generation using coal as 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 here and I again want to thank all my
faculties, staff of Wanakbori Thermal Power Station to give me this great pleasure of the training.
