The document summarizes an industrial visit by 48 4th year mechanical engineering students and 1 faculty member from Crescent University to the Neyveli Thermal Power Station 1 operated by NLC India Ltd. The students visited the training center where they learned about the thermal power station process. They then toured the boiler section and turbine/generator floor, where a guide explained the water feeding, reheating, and regeneration systems. The visit helped students observe the different energy conversion stages firsthand and clear up questions they had. Neyveli Thermal Power Station 1 consists of 6 units of 50MW each and 3 of 100MW each, providing power to Tamil Nadu. It underwent a life extension program to continue operating after initially being

Industrial Visit Report
Name of Industry: Neyveli Thermal Power station 1, NLC India Ltd.
Date of Visit: 07/11/2017
Faculty Coordinator: Dr. Serajul Haque
Class: 4th
Year B.Tech. Mechanical Section “D”
Number of Visitors: 48 students + 1 Faculty Member
School of Mechanical Engineering, Crescent has organized an industrial visit of Thermal Power
Station, Neyveli for 4th
Year B.Tech Mechanical students. 48 students along with 1 faculty member
visited the thermal power station on above mentioned date. NLC India has five pithead Thermal
Power Stations with an aggregate capacity of 3240 MW. Further, NLC India has so far installed
29 Wind Turbine Generators of capacity 1.50 MW each and also commissioned 10 MW Solar
Photo Voltaic Power plant in Neyveli, resulting in an overall power generating capacity of 3287.5
MW. Following sections of the Neyveli Thermal Power station 1 are visited.
1) Training center
2) Boiler section
3) Turbine/Generator floor

At the training center, Mr. Selvan Raj, Deputy Engineer, Training Center, explained the working
cycle of thermal power station. Students visited one small scale model of equipment used in the
power plant station I. We visited the Boiler Section and Turbine where Mr. Selvan Raj guided us.
He explained water feeding mechanism, moreover reheating and regeneration concept of thermal
power plant are also explained. At boiler section we visited FD fan, ID fan, PA fan, boiler furnace
area and other auxiliary devices essential for boiler operation.
The visit was very fruitful as we observed each of energy conversion stages used in power plant
starting from fuel section to switch yard. We observe very important information like practical
data which are not available in books and other literature. Many of our doubts are cleared by the
discussion with experts of the plant.
The 600 MW Neyveli Thermal Power Station-I in which the first unit was synchronized in May'62
and the last unit in September'70 consists of six units of 50 MW each and three units of 100 MW
each. The Power generated from Thermal Power Station-I after meeting NLC's requirements is
supplied to TANGEDCO, Tamil Nadu which is the sole beneficiary. Due to the aging of the
equipments / high pressure parts, Life extension programme has been approved by GOI in March
1992 and was successfully completed in March’99 thus extending the life by 15 years. In view of
the high grid demand in this region, this power station is being operated after conducting Residual
Life Assessment (RLA) study. GOI has sanctioned a 2x500 MW Power Project (Neyveli New
Thermal Power Plant – NNTPS) in June 2011 as replacement for existing TPS-I. [Source-
