Jan 09, 2019· Plant heating and manufacturing processes inevitably result in the production of waste. While some waste is unavoidable, waste heat is one type of waste that can be repurposed instead of merely discarded. Redirecting waste gas and utilizing it as a heat source can reduce the amount of waste produced by a facility and released into the atmosphere.

Process heat from steam boilers. 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.
