Waste Heat Recovery - Energy

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
