Mixing Type Burner

  SR multichannel gas burner and mixing type burner are developed based on four-channel burner;
  It is designed for combustion of varioius gas at rotary kiln. This burner can gurantee the advantages and specialty of four-channel burner. It can not only expand the adpabilities of fuels, but also solve problem which single fuel can not meet production demand.

Technical introduction

This type of burner can be divided into two kinds according to exit cross-sectional area, adjustable type and unadjustable type. The following picture is chart of unadjustable type.
RS series four-channel coal powder is mainly composed of pipeline, spray nozzle, flygate, pressure measuring instruments and protection layer.
Pipeline: consists of axial flow duct, swirl wind duct, coal wind duct, center wind duct and fuel pipe. Because fuel pipe is used for ignition, the equipment is always called as four-channel burner.
Nozzle: it is made from special materials. Spray outlet area of different series of burners can be adjusted. Then, the speed of wind sprayed can be adjusted. Nozzle is one of key parts to gurantee shape of flame and service span.
Metal corrugated compensator: it is an important part to connect all ducts, insulation and the adjustment of flame shape.
Flygate: it is used to adjusting wind volume.
Pressure measuring instruments: present the spouting speed of ejector indirectly;
Protection layer: it is also called fireproof layer; poured by users.
Structure chart of four-channel coal powder burner
It is designed for combustion of varioius gas at rotary kiln. This burner can gurantee the advantages and specialty of four-channel burner. It can not only expand the adpabilities of fuels, but also solve problem which single fuel can not meet production demand. At present, it has been applied to rotary kiln in chemical and metallurgy industries. It is well-received by its users. 

Advantages

Features:
1. Regular shape of flame; stable flame; the flame will not touch the kiln liner; the service span of kiln liner can be expanded;
2. Good mixture of gas fuel, primary wind and secondary air; full combustion; can improve thermal strength of kiln; reduce the proportion of primary air; improve the production output of kiln and reduce thermal consomption;
3. Smoking collecting hood forms a bowl shaped effect and flames. There is no strong eddy current at the beginning, which avoids temperature peak. The distribution of flame is even and reasonable, which can effectively protect kiln body and guard board.
4. Reduce the CO and NOX content in exhaust air, which is beneficial for safe running and environmental protection of electric dust collector.
5. Nozzle adopts special materials which is resistant to high temperature.

Working principle

Principle:
   The fuel gas is erupted outside according to a certain diffusion angle from the gas pipe. High momentum and angular momentum is transferred from the outside to the adjacent wind swirling. With high speed spiral forward, fuel gas continues outward diffusion and meets axial flow wind beam which is injected with a high speed.  Involvement of axial fan beam further enhances mixing of fuel gas and air (including secondary wind around). The degree of flame divergence can be adjusted the flame. The flame can be adjusted according to the need of the length and thickness in order to achieve the required shape. The center wind promotes combustion of a small amount of central gas and CO, which makes more sufficient combustion and plays a role for steady flow. Because of the burning mechanism and high speed of swirl wind and axial flow wind, the combustion is very rapid and complete. As shown in figure 1.
