Before using biomass burner, check the explosion-proof valve should be prepared in advance, to ensure the normal operation of safety equipment. With the view of vertical biomass gasifier burner characteristics
Biomass gasifier burner vertical features
1970s, domestic biomass gasifier burner for melting aluminum and the continuous casting and rolling line flow composition, studying the characteristics of the cupola, the development of a shaft furnace for melting aluminum (melting rate 2-10t / h). The timing of participation charge from the roof, puddle constantly being melted sink. Bosh burner installed in the flame and gas rises, the heat exchange operation of the reverse charge is then discharged through the chimney from the roof. Its high thermal efficiency, open, shutdown convenient. This furnace in wires, cables professional widely used. In recent years, along with advances in casting skills, more and more domestic investment in the use of vertical biomass gasifier burner. The picture shows a large domestic aluminum enterprises use a round furnace. The furnace is circular, circular dome roof, above a plate, steel frame and closure increasing device. Lid surrounding the choice of a water jacket, the inner wall of masonry brick arch. When feeding, the lid is removed, the material from the top of the stove participate crane. Because a large amount of feed, and reducing the charging time, so that the production cycle time. Four burners evenly distributed in the furnace wall, and with four flue ports to facilitate uniform rotation of the furnace gas. Its characteristics are: type furnace: furnace and the bath are cylindrical shape. Structure: All the burners are disposed in a tangential direction of the furnace, so that high speed rotation of the gas burning in the furnace, and the skew angle must burner, high temperature gas stream toward the bath, and greatly enhance the convective heat transfer gas in the furnace and conductive heat transfer liquid aluminum, aluminum fluid temperature is relatively uniform, the velocity of the material to speed up melting the bath, and greatly improving the thermal efficiency of the furnace and to the melting of the furnace and eliminates dead ends. Feed: participation from the top of the furnace by mechanical means, therefore, small labor intensity, fast feed rate, low ambient temperature, high labor efficiency. Sealing: In addition to the essence, slag, when alloy components demand open stove door, stove are in sealed condition, the fire did not run phenomenon. So good sealing furnace, less heat is lost. Repairs: small daily workload protection, low repair costs, repair, overhaul cycle is long.
