It is equipped on shell with the shower disk junction and connects the combustion section and a plurality of ventilation holes of the shower disk.
Implement the transformation low NO of the present invention, have the advantages that：Use the transformation low nitrogen burning of the present invention
During device, the coal dust by mixing enters the first taper mixing unit through the first air hose, and mixed coal powder enters in the first taper mixing unit
It is compressed later, then enters to the second taper mixing unit through the second small-caliber end, mixed coal powder is led with continuous thread at this time
Wind item is rotated and be sufficiently mixed for the first time, and after mixed coal powder goes out the second cone blender, the second air hose is to combustion
Air is blown into burning portion to be sufficiently mixed for the second time, control igniter is lighted a fire, and third air hose is in process of coal combustion
Air is blown into combustion section so that coal dust intermixture is fully burnt, abundant burning so as to fulfill coal dust intermixture, with
And reduce nitrogenous exhaust gas discharge.
Description of the drawings
Below in conjunction with accompanying drawings and embodiments, the invention will be further described, in attached drawing：
Fig. 1 is the structure diagram of present invention transformation low NO.
