Why Use De Gassified Water In Waste Heat Boiler, steam power cycle

How can we use waste heat?

Waste heat is the energy that is not put to use and is lost into the environment. Heat recovery provides valuable energy sources and reduces energy consumptions. Recovering the waste heat can be conducted through various waste heat recovery applications to provide valuable energy sources and reduce the overall fuel usage and carbon footprint.
