Asphalt Mixing Plant Burner

The classification of asphalt mixing plant burner are oil and gas dual-purpose burners, low-pressure atomization burners, gas burners and oil burners. The bitumen flue gas in the asphalt plant burner contains a variety of organic substances, including carbocyclic hydrocarbons, cyclic hydrocarbon derivatives and other compounds (such as benzene). And pyrene, benzanthracene, carbazole, etc.). The particle size is mostly between 0.1 and 1.0 μm, the small is only 0.01 μm, and the large is about 10.0 μm. The main way it harms human health is to attach to the floating dust below 8 um and be inhaled into the human body through the respiratory tract, causing damage to human health. Therefore, it is very necessary to purify the asphalt flue gas so that the emission meets the atmospheric environmental standards.

There are many methods for treating asphalt smoke, including mechanical separation method, adsorption purification method, low temperature plasma, filtration method, electrostatic trap method, and combustion method.
1, The fuel of asphalt mixing plant burner uses oil and gas dual-purpose fuel supply system, and the fuel system adopts medium atomization technology (bubble atomization burner), which has good atomization effect, full combustion, energy saving and environmental protection. The gas system uses all stainless steel pneumatic butterfly valves and proportional control valves to intelligently control the ratio of gas to wind. The gas nozzle adopts an adjustable angle method plus a central swirl, turbulence mixed and staged combustion, full combustion, low nitrogen and environmental protection. The asphalt plant burner achieves the best combustion effect through real-time monitoring of material temperature, PLC intelligent control and frequency conversion to adjust the air-to-oil ratio, reducing pollution, reducing unit energy consumption and improving users' comprehensive benefits.

2, The asphalt mixing plant burner machine adopts high-quality centrifugal fan and intelligent damper control system, and adds an asphalt flue gas recovery system to the air inlet. During normal production, the asphalt flue gas generated during the discharging of the mixing tank can be passed through the flue gas recovery system, flue, and intelligent The air door is controlled to enter the burner. After high-temperature combustion, it can completely eliminate harmful substances in the flue gas, so as to meet the environmental protection requirements and protect human health.
