Abstract
The power sector is one of the sectors of the India's economy. The development of the country to a large extent is dependent on the growth of this sector. Through the progress of the power sector during the past four decades has been sustainable, the power industry has been unable to fulfill primary obligation of production quality power supply in required quantity. We did our project in Stage- 4, Unit -7 of Dr. Narla Tata Rao Thermal Power Station, Vijayawada and analyzed the performance of the boiler of the above-mentioned unit of capacity 500MW. Our project was mainly concerned with the Boiler Operations & Maintenance Department (O&M). Initially, we calculated the performance and efficiency of the boiler. The Computational Fluid Dynamics (CFD) approach is utilised for the creation of a two-dimensional model of the economizer coil. Using mild steel material in the economizer part it gives better performance compared with the carbon steel material. The fluid flow temperature, pressure is increase and velocity is decrease field of fluid flow within an economizer tube using the actual boundary conditions have been analyzed using CFD tool. So the boiler performance will be increased. And the experimental setup is from Dr. NTTPS, Vijayawada having the unit no IV of 500 MW energy generations.
