Ash Handling & Storage Method using Hydrobin to Avoid Ash Pond at Stage-IV of Dr. Narla Tata Rao Thermal Power Station, Vijayawada
The objective of this project is to focus on the hydrobin employed in stage IV of NTTPS which not only give high efficiency but also reduce the harmful effects of ash ponds on the environment. Ash ponds are becoming a menace to the environment in many ways.
Ash pond failures, increased government regulations, growing demand for reuse of ash, etc are all forcing thermal power plants to reevaluate the ash-handling system and NTTPS is not behind in adopting these latest advancements. Hydrobin separates the bottom ash from water thereby avoiding ash ponds. The dry ash that is obtained can find their applications in various other industries while the water is recirculated in the plant. In the further pages we shall get an insight about what Hydrobin is, it's construction, it's working, it's advantages and defects.
