What is an Economizer? Purpose, Classification, Advantages

In a thermal power plant, an economizer heats fluids or recovers residual heat from the combustion product, i.e. flue gasses, before they are released through the chimney. Flue gasses are the combustion exhaust gasses produced by power plants, and they primarily consist of nitrogen, carbon dioxide, water vapor, soot, and carbon monoxide.
