    Ultra-low NOx Combustion Technology
    The method of improving combustion technology to reduce NOx emission is called low NOx combustion technology. Pyneo's technology has adjustable pulverized coal concentration combustion, low oxygen combustion, staged combustion of fuel, design of offset peripheral air, tangential combustion of primary and secondary air, staged combustion of multi-stage SOFA air, flue gas recirculation combustion, etc., and won the second prize of National Science and Technology Progress Award.
    Main Content

    This technology is suitable for the combustion control of various fuels, such as solid fuels such as bituminous coal, lean coal, anthracite and lignite, liquid fuels such as oil and coal water slurry, and gas fuels such as natural gas and dry gas.

      Technical Advantages

      a) Reduce NOx emissions by 40%-70% for general coal quality.

      b) Reduce the NOx emission concentration to 150-250 mg/Nm3 for lignite.

      c) Reduce the NOx emission concentration to 200-300 mg/Nm3 for bituminous coal.

      d) Reduce the NOx emission concentration to 500-600 mg/Nm3 for anthracite.

      e) Reduce the NOx emission concentration to 400-500 mg/Nm3 for lean coal.

      The removal efficiency of NOx is from 40% to 70%. The efficient combustion of the boiler can be ensured. The coking condition of the boiler is improved. The ultra-low NOx combustion technology can be applied in wide ranges of coal adaptability, which can enhance the low-load stable combustion of the boiler. It has independently developed, designed, processed and manufactured core devices such as low NOx burner with adjustable pulverized coal concentration, high-efficiency intensified combustion nozzle, etc.
