Recovery and utilization of waste heat in a coal based sponge iron process

Out of the total heat generated from coal based DR plant, only 35% of the heat is used for reduction and the rest is lost with the exhaust gases. To tap this heat a waste heat recovery boiler (WHRB) was installed to generate process steam. But this recovery is

Waste heat - Energy Education

Waste heat is the unused heat given to the surrounding environment (in the form of thermal energy) by a heat engine in a thermodynamic process in which it converts heat to useful work.The second law of thermodynamics states that waste heat must be produced when converting a temperature difference into mechanical energy (which is often turned into electrical energy in power plants).

FUNDAMENTALS OF COMBUSTION AND HEAT LOSSES

HEAT LOSSES in a boiler are well described by the American Society of Mechanical Engineers (ASME) in its rigorous PTC4.1 power test code (1973). The test code applies to any type of fuel used. However, natural gas or fuel oil fire most boilers and heaters in Canada.
