How Is Waste Heat Recovered In Waste Heat Boiler

Waste Heat Recovery Calculations | Heat Recovery Unit | …

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 unit - Wikipedia

Recovering waste heat often reduces the need for steam in a plant. Consequently the boiler's fuel consumption is reduced, as are greenhouse gas emissions and the load on the cooling system. Recovered heat can also be used for preheating the boiler feed, lowering fuel consumption. Process heat from fired heaters/furnaces
