The unique design guarantees the well mixing of pulverized coal, primary air and secondary air. HJ burner is with high combustion efficiency, powerful push force, large velocity difference that enables the homogeneous mixing of the wind and pulverized coal, Supersonic wind speed, superior flame shaping, high flame intensity and rigidity, stable flame performance. It has been repeatedly verified as a trusted burner with superior energy-saving and productivity improvement performance by more than 168 cement plants. Key features 1 channel for axial air :Keep the flame shaping and rigidity channel for swirl air: Keep the flame intensity channel for vortex air(Semicircle orifice with Taper: Keep the flame stability channel for pulverized coal 2 wind through the channel match the lowest coefficient of air resistance and adjustable 3 Scientific Golden Angle Design 120 high wind speed and use ratio 4 with 5 expansion joint and 3 regulator Benefits 1 supersonic wind speed,powerful push force, large velocity difference, wind and coal mixed evenly, high combustion efficiency 2 Primary air amount is 5.7% only, decrease the power and coal consumption 3 Superior flame shaping, high flame intensity and rigidity, stable flame performance improved clinker quality. 4 flame shape adjustabl fit each specific rotary kiln type 5 Avoid the peak temperatur lower NOx 6 wear resistance corrosion resisting longer lifespan 7 improved productivity
