Heat Recovery | Enerquip

Flue gas recovery exchangers also work with boiling systems to recover heat from waste flue gases and use it to preheat water entering the boiler. This reduces the energy consumed in warming up the water to the required level increasing efficiency and delivering the same amount of heat to the boiler with 4% less gas. Interchangers are shell and tube heat exchangers that often use one product stream to heat or
