  • Monitoring flue gas temperatures to monitor stack loss

    In oil and gas fired boilers, due to practical limitations of the burner, some excess air needs to be supplied to ensure complete combustion. If this excess air is higher than required, it carries away useful heat to the atmosphere via the chimney. By rule of thumb, the maximum acceptable stack gas temperature is 30oC over the steam temperature.Learn More

  • What temperature should a condensing boiler be set at

    For the boiler to work at its most efficient, the heat exchanger needs to be equal to or below the dew point temperature. The dew point temperature is a measurement that determines the humidity of air and is the temperature at which water droplets form in the heat exchanger. For gas boilers…Learn More

  • Efficiency Of Steam Boiler Systems | Steam Boilers In India

    L1 – Loss due to dry flue gas (Sensible heat of the flue gas) Loss due to dry flue gas is a major loss in indirect efficiency. If the flue gas temperature leaving the boiler is high it can reduce efficiency. L2 – Loss due to hydrogen –formed water (moisture in fuel) The high hydrogen content of the fuel reduces the efficiency of the boiler.Learn More

  • Improving Energy Efficiency of Boiler Systems

    • If two boilers of similar length and width are compared and one has more flue gas passes (number of times the flue gas travels through the boiler heat exchanger), the boiler with the greater number of passes should have a lower stack temperature.Learn More

  • Boiler Economizer: Boost Your Boiler's Performance I RasMech

    Mar 03, 2021 · High pressure steam boiler stack temperatures often range from 400 degrees F to 650 degrees F. That high temperature exhaust is wasting energy. That is where boiler economizers come in to reduce that heat loss. Remember, we need a fluid that can use the heat AND is at a lower temperature than the flue gas.Learn More

  • Protecting Boilers Against Flue Gas Condensation | 2017-08

    Aug 14, 2017 · In addition to boilers fueled by gas, propane, and fuel oil are boilers burning cordwood, wood chips, and wood pellets. These solid-fuel boilers also require protection against sustained flue gas condensation and can be equipped with the same type of hardware to …Learn More

  • Steam Boiler: What Is It? How Does It Work? Types Of

    Other methods to control steam temperature are through the use of flue gas circulation, flue gas bypass, or the tilting angle at which the burners fire the furnace. The simplest method for controlling steam temperature is to monitor the temperature of the steam as it exits the boiler and change the position of the spray water valve.Learn More

  • Flue gas system | Bosch steam boiler planning Commercial

    The material of the entire steam boiler flue gas system must be suitable for temperatures up to 350°C. If the boiler is equipped with a fourth pass or a waste heat boiler for utilisation of the waste heat in flue gases from a CHP module or a gas turbine, the flue gas system must be suitable for the highest temperature that can occur in each case.Learn More

  • What are the requirements for the exhaust gas temperature

    Jun 05, 2019 · The higher the exhaust gas temperature, the lower the thermal efficiency of the boiler. FANGKUAI Boiler's natural gas boilers are equipped with advanced condensing technology to condense high-temperature flue gas, release heat again, and the exhaust gas temperature is also reduced, which can be below 120 °C.Learn More

  • Flue Gas Recirculation: History and Uses - EnviroPower

    Jun 19, 2019 · In order to reduce NOx, recirculated flue gas must be mixed with air before entering the burner or cylinder. This is somewhat different than the temperature control setup, where flue gas in blown directly into the boiler. Thus, while FGR is effective for both boiler temperature control and NOx reduction, they require different injection points.Learn More
