The multi-channel pulverized coal burner produced by Zhengkuang Machinery has axial flow, coal wind, swirl wind and center wind from outside to inside. It is a four-channel burner with an oil gun channel in the center. The outlet area and air volume of each duct are easy to adjust. It can burn inferior coal, low-volatile coal, anthracite, etc.

The multi-channel pulverized coal burner consists of pipelines, nozzles, metal corrugated compensators, butterfly valves, pressure measuring instruments and protective layers. It is made of special materials. The outlet area of each duct is adjustable. The butterfly valve is used to adjust the air volume. The pressure measuring instrument is used to measure the air volume and wind speed of each duct. The external user can cast the refractory protective layer by himself. This series of combustion has a total of eight models, with a coal feeding capacity of 1.2-6.5t/h, which can meet the production needs of rotary kilns with a diameter of 1.9 meters to 4.0 meters.

Application field

The combustion system of rotary kilns in the power, chemical, metallurgical, building materials and other industries.

Advantages

1. Flexible and convenient online adjustment, the flame length, thickness, and strength can be adjusted at any time according to different requirements;

2. The flame shape is more regular, complete, and stable, which is conducive to the long-term safe use of the kiln lining;

3. Adaptable to various coal qualities, it can be used for inferior coal, low-volatile coal, anthracite, etc.;

4. High combustion efficiency, greatly reducing the formation of NO, reducing harmful exhaust gas emissions, and is beneficial to environmental protection.
