Introduction of Multi channel gas burner pulverized coal burner rotary kiln burner for rotary kiln

A rotary kiln is a kind of industrial equipment used for material heating and processing, which is widely used in cement, metallurgy, chemical industry, etc. Multi channel gas burner pulverized coal burner rotary kiln burner for rotary kiln refers to various parts and components which are necessary for maintaining and repairing the normal operation of the rotary kiln, such as cylinder, baffle wheel, pallet, sealing device and so on.

Features and advantages of Multi channel gas burner pulverized coal burner rotary kiln burner for rotary kiln

High-temperature resistance: Due to the extremely high temperature of the working environment of the rotary kiln, the spare parts are usually made of refractory materials or special alloys to ensure that they can work stably under high temperatures.

High abrasion resistance: Long time material friction and chemical erosion require spare parts to have excellent abrasion resistance to prolong service life.

High structural strength: in order to withstand heavy loads and the pressure of continuous operation, the design of spare parts will place special emphasis on structural strength and reliability.

Easy to install and maintain: Considering the need for frequent replacement, many spare parts are designed to be simpler and easier for quick installation and maintenance.

Strong adaptability: different industries have different needs for rotary kilns, so spare parts need to have good versatility and adaptability to meet diverse application conditions.

Specifications of Multi channel gas burner pulverized coal burner rotary kiln burner for rotary kiln

This burner handles both gas and pulverized coal firing in rotary kilns. It combines two fuel types efficiently. The burner fits standard rotary kiln inlets. It ensures stable combustion and good flame shape.

The main body uses high-quality heat-resistant steel. This steel stays strong under extreme kiln temperatures. The outer shell is also robust steel. Internal components withstand high heat and abrasion. Refractory materials line critical areas. This protects the burner structure.

Gas enters through dedicated channels. Pulverized coal flows through separate, optimized pipes. Primary air carries the coal powder. Secondary and tertiary air channels control combustion. This design allows flexible fuel mixing. Operators adjust gas and coal ratios easily.

Operating pressures are important. Coal transport pressure typically reaches 15-20 kPa. Primary air pressure is similar. Gas supply pressure depends on the gas type. It usually ranges from 20-50 kPa. Secondary air pressure is lower. It supports flame stability.

Combustion temperatures are very high. They easily exceed 1600°C. The burner tip withstands this intense heat continuously. Flame length and shape are adjustable. This is vital for optimal clinker formation inside the kiln. The flame must cover the material bed properly.

Key features include strong ignition. Reliable flame stability is critical. Operators control the flame shape precisely. The design minimizes NOx emissions. Fuel consumption stays efficient. The burner handles varying load demands well. Maintenance access is straightforward. Spare parts are commonly available.

5 FAQs of Multi channel gas burner pulverized coal burner rotary kiln burner for rotary kiln

What does this burner do?
It burns gas and pulverized coal inside a rotary kiln. This gives you fuel flexibility. You can use one fuel or both together. It creates the intense heat needed for processes like making cement or lime.

How does the multi-channel design work?
Separate pipes deliver gas, coal, and air into the kiln. This keeps the fuels apart until they mix and burn right at the burner tip. The design ensures stable, efficient combustion. It prevents problems like flame blowback.

How do you start the burner?
Always ignite the gas first. Gas lights easily and provides a reliable pilot flame. Once the gas flame is stable, you slowly introduce pulverized coal into the hot gas stream. The coal ignites quickly from the existing flame. Never try lighting coal directly without the gas flame first.

Can you control the flame shape?
Yes. You adjust the flow rates of gas, coal, and combustion air. Changing these flows alters the flame’s length, width, and temperature profile. This control is vital for optimal heat transfer inside the kiln. It helps achieve the right product quality and saves fuel.

Is maintenance difficult?
Regular checks are essential. Focus on the burner tip and nozzle areas. These parts face high heat and wear from the coal particles. Inspect them often for erosion or blockages. Replace worn parts quickly. Keeping the burner clean and aligned prevents efficiency drops and costly downtime.
