Multi-channel Pulverized Coal Burner

Multi-channel pulverized coal burner

Product introduction: The multi-channel pulverized coal burner produced by our company consists of axial flow air, coal air, swirling flow air and central air respectively from the outside to the inside. It is a four-channel burner with oil gun channel in the center, and the outlet area and air volume of each air channel are convenient to adjust. It can burn inferior coal, low volatile coal and anthracite.

Model: LY-1 ~ LY-4A

Coal consumption: 1.2-6.5t/h

Application: combustion system of rotary kiln in electric power, chemical industry, metallurgy, building materials and other industries.

Multi-channel pulverized coal burner product introduction

The multi-channel pulverized coal burner produced by our company is composed of pipes, nozzles, metal corrugated compensators, butterfly valves, pressure measuring instruments and protective layers, etc., made of special materials, the outlet area of each air 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 air duct, and the external user can pour the refractory protective layer by himself. This series of combustion a total of eight models, feed volume 1.2-6.5t/h, can meet the diameter of 1.9m-4.0m rotary kiln production needs.

Outstanding advantage

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

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

3, Adapt to a variety of coal quality, poor quality coal, low volatile coal, anthracite can be used;

4, High combustion efficiency, greatly reduce the formation of NO, reduce harmful exhaust emissions, conducive to environmental protection.

Working principle

The pulverized coal is sent into the kiln by the centrifugal fan or Roots fan through the burner coal air, and the swirling wind spins the pulverized coal at a constant Angle, so that the pulverized coal is dispersed and fully burned. The external wind is the axial flow wind, which can gather the divergent fire pattern and the central wind plays the role of stabilizing the flame. In normal production, the flame thickness is adjusted by adjusting the swirl wind, and the length of the flame is adjusted by adjusting the axial flow wind to meet the production. When the swirl wind cannot be met, it is necessary to expand the central air pipe to adjust the distance of the wind wings to change the effect of the swirl flow. The adjustment of the axial flow wind, the swirl wind and the central wind is realized by switching the pipeline valve.
