Huge amount of energy in the form of waste heatis discharged into the atmosphere in various industrial sectors such as power plant, cement industry, iron and steel industry etc.The quantity of heat released into the atmosphere has been classified into 3 categories namely, low, medium and high temperatures. The amount of green house gas emissions carried away by the exhaust gases to the atmosphere isalso significant. Major component of the exhaust gases is carbon dioxide and little amount of methane and nitrous oxide.Recovering the waste heat from the exhaust gases not only results in power production but also reduces the amount of green house gas emissions, which is the need of the hour.
