A concentrated opposite blowing multiple classification NOx combustion method of the protection environmental technology area. The invention is that along the furnace height direction fall into the main combustion chamber, reducing area and burnout area, in the main area the wind fall into two shades in a level direction by firebox , a strong wind rip into the furnace burning side, after the promotion is reversed to change, and the secondary wind cut into the furnace, joint with light wind and form rotary stability aerodynamic field, so most of the wind pulverized coal is led to the furnace central region, ultimately in the heater form a light wind wrap a strong wind, a second air parcels light wind, and wind wrap powder situation, a second wind and light wind in the near wall region of water wall form oxidizing atmosphere, away from water wall region the pulverized coal burning. The invention achieves ultra-low NOx emission, while the burning area prevents to slag and ensure the high combustion efficiency etc. characteristics.
