Dual-scale low NOx combustion technology
Dual-scale low NOx combustion technology advances in achieving differentiation of characteristics 3-field （temperature，air and concentration of pulverized coal, orbit of moving coal particle ）in relevant zone in spatial scale through modification of combination of furnace combustion jet stream as well as achieving differentiation of characteristics 3-field in relevant nodal point zone during process scale (the 3-field characteristics on the two scales are different from other zones).
Combined with “partition optimization and debugging method”, the 3-field characteristics formed on the two scales can truly realize the function of anti-furnace slag ，high-performance of stable combustion and substantial NOx emission reduction. It will benefit combustion. This technology can be targeted to address difficult problems regarding pulverized coal boiler operation and environmental protection.
■ The significant reduction of NOx with high burning rate, boiler efficiency remains unchanged
■ Solution to boiler slagging and improvement of the security of equipments.
■ Realization of low oxygen running without lowering boiler efficiency.
■ The integration of plasma ignition with speeding up the burning of pulverized coal and fuel oil saving for start up.
■ Improved the low load combustion stabilization and the reliability of the boiler operation.
■ Simple structure, easy construction, flexible operation.
■ Less initial investment, one-time retrofit investment, no running cost.
■ Retrofit period is short, usually accomplished in one overhaul time.
