Waste Heat Recovery Calculations | How much energy

Waste heat flow rate. Waste heat comes typically in the form of hot air, smoke or steam. An important factor is thus the flow rate of the exhausted air. The flow rate states the volume or the mass of air that gets exhausted and determents the potential value of the extracted heat. The flow rate also depends on the medium the heat is contained in.

WASTE HEAT RECOVERY - Thermopedia

Waste heat recovery aims to minimize the amount of heat wasted in this way by reusing it in either the same or a different process. Waste heat can be recovered either directly (without using a heat exchangere.g., recirculation) or, more commonly, indirectly (via a Heat Exchanger). Direct heat recovery is often the cheaper option but its use
