The specific embodiment
As shown in Figure 2, air supply duct 100 is annular passages of existing alkali boiler.Air distribution airduct 200 is located in the air supply duct 100, and the duct wall 101 that an end of air distribution airduct 200 passes air supply duct 100 1 sides is provided with tuyere 280, and tuyere 280 is that two interconnective parts constitute with air supply duct 100 in the present embodiment.Duct wall 101 is provided with sealed support 106, and tuyere 280 is fixed in the sealed support 106.
Tuyere 280 comprises the conduit 281 that is connected with air distribution airduct 200, and conduit 281 inner chamber ends are air outlets, and the outer end face 282 of air outlet is recessed to what mate with the water screen tube of bending.Crooked water screen tube is the cooling structure on the furnace wall; The version of the end face 282 that the air outlet of tuyere 280 is outer realizes fitting with crooked water screen tube; There are current logical in the crooked water screen tube, can play the cooling protection effect, avoid its temperature too high tuyere 280.Tuyere 280 can be provided with cooling device in addition like this.
The cross sectional shape of the inner chamber of the inner chamber of conduit 281, air outlet 283 and air distribution airduct 200 is identical, all is oval shape, and is as shown in Figure 5.
