Sep 13, 2018 · Boiler flue gas contains useful amounts of energy that can be captured with the use of an economizer. Once captured in the economizer, the heat from the flue gas can be utilized via heat transfer to preheat the feedwater entering the boiler. In most cases, a decrease of flue-gas temperature by 40°F (4°C) will increase efficiency by 1 percent.
