Waste Heat Recovery in Cement plant IJERT

The Waste heat is heat, which is generated in a process by way of fuel combustion or chemical reaction, and then dumped into the environment even though it could still be reused for some useful and economic purpose. The essential quality of heat is not the amount but rather its temperature of the waste heat gases and the economics involved.
