Product Description

Coal, Gas Multifuel Burner / Dual Fuel Burners Manufacturer in China



Pulverized Coal Burner Introduction:
Multifuel burner is a new combustion device burning gas and coal powder in rotary kiln. It has a unique structure and reasonable parameters to ensure gas, coal powder and air, primary air and secondary air mixed sufficiently. It brings greater thermal intensity, higher combustion efficiency and easier adjustment. It can be widely applied to various rotary kilns in metallurgical and chemical industry.
The burner can mix gas and coal powder for co-burning, and also can realize gas or coal powder separate burning.

The rotary kiln’s combustion system in electricity, chemical, metallurgy, building materials industries.

Multifuel Burner Structure:
Multifuel burner is mainly composed of piping, nozzle, Metal Ripple Hose compensator, butterfly valves, pressure measurement instruments and protective layer. Its main structural features are:
1. Pipeline
There are five layers from outside to inside. They are axial flow duct, cyclone duct, gas channel, coal air channel and the central channel.
2. Nozzle
Processed by special material, its outlet are can be modified to adjust the ejection speed.
It is one of the key components which can maintain the flame shape and service life time.
3. Metal Ripple Hose Compensator
The Metal Ripple Hose Compensator is the main components of pipe connecting, sealing and flame shape adjusting.
4. Butterfly Valves
There are butterfly valves at the inlets of axial flow air, cyclone air and central air. Each air volume and proportion can be adjusted by change the channel outlet area to modify the ejection speed.
5. Pressure Measurement Instruments
They are used for indirect display air speed of each channel in burners.
6. Protective Layer
It is the refractory casting layer which is cast by user;
