Blast furnace gas burner production process required oil heating, but the existing producer gas with water and a lot of tar, imported burner can not run. We find a lot of domestic manufacturers can not solve this problem. Then the reason of blast furnace gas burner clogging
	Causes Blast Furnace Gas clogging

Causes Blast Furnace Gas clogging
Plant tissue burner clogging reasons deepen analysis, the analysis of the following reasons: the impurity from the blast furnace gas, blast furnace gas and conveyed to the boiler together with the combustion region. In the blast furnace gas passes through the swirl vanes rotate and generate air flow generated in the radial velocity of the conduit, the air flow hitting the rotary blade, some impurities adhering to the swirl vanes. Blast furnace gas burner swirl vanes planning unreasonable, did not fully consider the impact of fuel impurities. Blast furnace gas passes through the swirl vanes in significant savings, and the number of blades is too small inter-blade passage, exacerbated accumulation of impurities. Swirl vanes impatience corrosion, corrosive and acidic blast furnace gas, the swirl vanes produce pits after etching, adhesion exacerbated accumulation of impurities. Swirl vanes close to the furnace, impurities are high temperature sintering. Blast furnace gas pressure is low, the impurity gas is not easy by itself when the kinetic energy of the blow-off heap, the lower the pressure of the blast furnace gas accumulation schematic impurities. Roadmap reduce clogging of blast furnace gas burner for a gas burner furnace causes clogging, the following summarizes the roadmap: reduced need to reduce clogging of the burner into the burner at a hetero mass of blast furnace gas boiler. Reduce clogging of the burner can be considered to transform the burner swirler vanes, without the influence of mixing gas with air, reducing the impact on the accumulation of impurities. Burner plate making should be used in heat and corrosion resistant material. Layer by layer cast burning boiler furnace when administered with a gas burner, the burner trace multilayer cast avoid burning, the gas flow rate results in saving scheduling valve intensified low impurity accumulation. Gas blow-off its own power is insufficient accumulation of impurities in the swirl vanes can be considered to use an external power source to a strong blow accumulated impurities. Blast furnace gas boiler structure according to the boiler pressure plan, the top is provided through large pores, the boiler operating at atmospheric pressure, away from the risk of explosion; boiler furnace Optional computer modeled to optimize planning, fully optimized boiler specification, the shape of the harmonic and beautiful. CLHS selection opposed vertical boiler combustion method in the burner, the fuel is combusted within a slight positive pressure furnace, baffle interposed smoke tube, slow smoke evacuation rate, heat strengthening, ensuring that the heating heat maximize fuel combustion boiler water, traveled boiler thermal efficiency;
