  • Flue gas heat recovery - netzero.im

    When your boiler is operating to run your central heating, some of the heat it produces is lost through the hot flue gases escaping to the outside air. If you are using hot water at the same time, a flue gas heat recovery system can recover some of this heat and use it to pre-heat your hot water supply, saving a bit more gas.Learn More

  • MAXIMUM ENERGY GAIN FROM FLUE GASES

    The residual heat contained in the flue gas downstream of the condenser is used to heat and evaporate water. This moisture is transferred to ambient air and directed to the boiler as hu-midified, pre-heated combustion air. This increases the mois-ture in the flue gas and the heat recovery in the upstream condenser. Fuel Boiler Filter Flue gas inletLearn More

  • 4-1 Recovery Boiler Equipment and Operation

    The effect of the exhaust fan was to reduce excess air and increase carbon monoxide to approximately 70 ppm. The situation was aggravated when the combustion air intakes were blocked because of fumes outside the boiler room. At this point, carbon monoxide production started to …Learn More

  • Improve Your Boiler's Combustion Efficiency

    Stack gas measurements indicate an excess air level of 44.9% with a flue gas minus combustion air temperature of 400°F. From the table, the boiler combustion efficiency is 78.2% (E1). Tuning the boiler reduces the excess air to 9.5% with a flue gas minus combustion air temperature of 300°F. The boiler combustion efficiency increases to 83.1% Learn More

  • Flue Gas Temperatures and PVC Venting - Cause for Concern

    The boiler is designed to run at capacity when you get a DHW call. I would expect the boiler to downfire; but I don't see this happening quickly enough. During the above scenario, I can quickly see a 20 degree, or less, temperature difference between the supply and return piping. This is bad news for the flue gas temperatures.Learn More

    More production through flue gas heat recovery. There is a lot of energy in flue gas due to the water (30–60%) contained in the fuel and steamed in the boiler. This energy escapes into the environment when the water is not condensed back into a liquid. With Valmet's advanced flue gas condensing technology, you can recover this energy and use it, for example, to increase district heat capacity; save …Learn More
