WebBoiler flue gases are often rejected to the stack at temperatures more than 100°F to 150°F higher than the temperature of the generated steam. Generally, boiler efficiency can be increased by 1% for every 40°F reduction in flue gas temperature. By recovering waste heat, an economizer can often reduce fuel requirements by 5% WebExtracting heat from the flue is not a good idea, especially as I don't really know of any type of control you can put at the top of the chimney to monitor temps to control your fan. You could just use the onboard controls of the fan, and check it against the temp you ultimately get at the top of the chimney. ...

WebSubstantial energy losses occur at Kilns because the flue gases still have a high temperature. This heat can be recovered with flue gas heat exchangers. The recovered heat can be reused to heat (combustion) … WebDec 8, 2024 · A heat exchanger is used to extract the heat from flue gas to working fluid. The waste heat from the flue gas can be utilized to heat the feed water coming out from the condensate extraction pump. WebWarm up combustion air by extracting heat from flue gas. The air preheater is corrosion resistant, easy to maintain and to clean. See Air Preheater. Stainless steel or Polymer Economiser.
