  • Flue Gas Temperature and Heat in the Flue Gas Flow …

    The heat efficiency of a flue gas waste heat boiler is the percentage of the effective heat in the heat injected into the fuel. The anti-balance test method is usually used to measure boiler thermal efficiency. The calculation formula for the thermal efficiency of the anti balance method: η= 100- (q2+q3+q4+q5+q6) 1. q2-flue gas heat lossLearn More

  • Improve Your Boiler's Combustion Efficiency

    The temperature of the combustion air entering the boiler is called ambient temperature, which can have a relatively noticeable effect on boiler efficiency. A variation of 40 degrees Farenheit can affect boiler efficiency by 1% or more, so this can drastically affect your operations.Learn More

  • Flue gas temperature or flue gas loss | Bosch steam …

    The flue gas temperatures at the boiler outlet are normally roughly 60K above the temperature of the product inside the steam boiler. At an operating pressure of 10 bar, which corresponds to a saturated steam temperature of 185°C, the flue gas temperature is therefore roughly 245°C. This corresponds to a flue gas loss of roughly 11%.Learn More
