Improving Boiler Efficiency by Using Economizer

The steam generating using a boiler is widely utilized in industry and power plants. A big portion of the worlds energy consumption is getting used in boilers. A small improvement within the efficiency of the boiler will help save an outsized amount of fuel and also help to reduce CO2 emissions. Therefore in this paper, we concentrated an approach toward the improvement of boiler efficiency by recovering a portion of the heat content of the flue gas. This is possible due to the most dominant device means an economizer. A boiler economizer works on the principle of heat transfer i.e., this device is nothing but a heat exchanger that uses the remaining energy of flue gas to heat the inlet water to the boiler. The recovered heat can also be utilized to preheat boiler feed-water, combustion air, or some other applications. Economizers also increasing the efficiency of the boiler will save you a lot of operating costs and eventually extend the life of the boiler system.
