An average boiler operates with an efficiency of approximately 66%, which means that 34% of the energy can be considered waste heat. An economizer, also called regenerators, is a type of heat exchanger that recovers heat from flue gasses to preheat fluids or puts it to use in another part of the production process. This recovery process saves on fuel consumption and costs, as well as it reduces the CO2 emission.
Investing in an economizer increases the efficiency with 8%. Including both an economizer and an air preheater realizes an even higher efficiency of 20%.
At Geurts, we engineer many types of economizers, or heat exchangers. For a boiler or steam generators fueled by natural gas, oil and biogas, both traditional tubes and finned tubes are applied depending on your production requirements. For a boiler fueled by coal, only regular tubes are optional due to the ash fouling.
