(1) Under the current situation, any manufacturer can try to wholesale Sandblast Gun transform the traditional continuous coal injection gun into a pulsed coal injection gun, which can effectively improve the combustion rate of pulverized coal without too much investment.
(2) Regarding the material of the spray gun, the author believes that the focus should be on improving the high temperature oxidation resistance of the front section of the spray gun, but I am not positive about the cermet lining the gun barrel, because although ceramics can improve some performances of the barrel, its thermal conductivity Poor performance, the cooling effect of the spray fluid on the spray gun shell is weakened, and its oxidation in high temperature hot air is accelerated, which also affects its service life. The author thinks that it is advisable to coat the high temperature paint with oxidation resistance on the spray gun.
(3) For those manufacturers with sufficient pulverizing capacity and oxygen production capacity, they should actively develop high-efficiency oxygen coal lances and adopt the form of double-gun injection. For those manufacturers whose pulverizing capacity and oxygen-making capacity are still difficult to match with high coal ratio in the short term, the structure and parameter optimization of the spray gun should be actively improved to improve the combustion rate of pulverized coal as much as possible, so that the limited coal pulverized get maximum use.
(4) Regarding the shape of the nozzle of the spray gun, I think that a multi-port and multi-flow nozzle can be used to make the pulverized coal flow occupy the cross-section of the tuyere to the greatest extent, but at the same time, the flow cross-sectional area of the nozzle should not be reduced as much as possible, so as to avoid the blowing of the nozzle. The flow rate is too high and the tuyere is easy to wear.
