Waste Heat Recovery Systems for Combined Heat and Power

Energy is lost via the stack. A gas engine or gas turbine is used to generate power and heat. Waste heat from the flue gas is recovered to generate steam or hot water. A typical CHP is already equipped with an economiser to preheat boiler feed water. The flue gas temperature downstream of this economiser typically tends to be >120 °C, which

Boiler Economizers and Waste Heat Recovery

Two solutions exist for recovering the waste heat from boiler flue gases. Conventional economizers preheat boiler make-up or feed water. Condensing economizers recover both latent and sensible heat from the flue gas, and are able to raise boiler efficiencies to over 90%. II Applications. Conventional stack economizers are more effective where a
