  • Boiler - Wikipedia

    Early boilers provided this stream of air, or draught, through the natural action of convection in a chimney connected to the exhaust of the combustion chamber. Since the heated flue gas is less dense than the ambient air surrounding the boiler, the flue gas rises in the chimney, pulling denser, fresh air into the combustion chamber.

  • Boiler Combustion | CleanBoiler.org

    Selective non-catalytic reduction involves the injection of a NOx reducing agent, such as ammonia or urea, into the boiler exhaust gases at a temperature of approximately 1400-1600°F. The ammonia or urea breaks down the NOx in the exhaust gases into water and atmospheric nitrogen. Selective non-catalytic reduction reduces NOx up to 70%.

  • Boiler Combustion Efficiency | Zirconia Oxygen Sensors

    This is optimised and maintained by measuring the output of oxygen level of the exhaust/flue gas by using an oxygen sensor in a closed loop feedback system to a controller for regulating the input mix. This is especially useful when the quality of fuel supplied may vary (i.e. gas from different sources).
