Ceramic sand rotary kiln burner: coal powder burner, rice bran burner

1、 Working principle of ceramic sand rotary kiln equipment:

The kiln body of the ceramic sand rotary kiln has a slope of 3% -4% (sine) with the horizontal plane. The entire kiln body is supported on the corresponding supporting wheel device by two wheel belts, and it is prevented from moving up and down in the axial direction of the kiln body through the blocking wheel device at the kiln tail; The transmission process is that the variable frequency motor drives the small gear to rotate through the reducer and its supporting coupling. The small gear meshes with the fixed large gear ring in the middle of the cylinder, and the final large gear ring drives the cylinder to rotate.

The fuel is sprayed into the kiln by the multi-channel rotary kiln burner produced by Zhengzhou Zhongwei Environmental Protection Equipment Co., Ltd. using gas or coal powder from the kiln head for combustion. The heat is transmitted to the materials through flame radiation, convection of hot gas, and conduction of kiln bricks, and then calcined into finished products. The calcination process involves the input of materials from the high end (kiln tail) of the kiln barrel. Due to the inclination and slow rotation of the cylinder, the material will undergo a comprehensive motion of rolling along the circumferential direction and moving along the axial direction, continuously conveying towards the lower end of the kiln cylinder (kiln head).

The material is fed into the kiln from the kiln head for combustion. During the flow process, the material meets the high-temperature airflow and is continuously heated to complete the physical and chemical reaction. The burnt clinker is discharged from the kiln head and enters the next process

2、 Characteristics of natural gas ceramic sand rotary kiln burner:

1. Multi channel design, with a sufficiently long flame length, the flame length and shape can be automatically or manually adjusted, and the high-temperature zone can meet the needs of the ceramic sand calcination process.

2. Energy saving design. The multi-channel ceramic sand rotary kiln burner is designed with multiple air duct structures, with accurate gas and air flow control, accurate mixing ratio, and sufficient combustion, achieving the goal of energy conservation.

3. Automation control design: ignition control, flameout protection control, pressure control, etc. According to the ceramic sand calcination process, automatic temperature control can be achieved. It can be connected to the central control room to achieve local and remote or mobile automatic control functions, and can monitor the working status of the rotary kiln burner in real-time, making it convenient for management.

4. Suitable for various fuels, it not only meets the requirements of environmental protection and low nitrogen emissions, but also achieves the energy-saving goal of reducing operating costs.

5. The combustion tube length of the rotary kiln burner extends into the kiln body: 2.0-4.5 meters, and the flame length is 4.0-9.0 meters, which can be adjusted online.

The multi-channel rotary kiln burners are classified according to the different fuels used: natural gas ceramic sand rotary kiln burners, blast furnace gas ceramic sand rotary kiln burners, coke oven gas ceramic sand rotary kiln burners, converter gas ceramic sand rotary kiln burners, ore furnace gas ceramic sand rotary kiln burners, yellow phosphorus tail gas and rice bran ceramic sand rotary kiln burners.

Diesel ceramic sand rotary kiln burners, heavy oil ceramic sand rotary kiln burners, gas generator rotary kiln burners, etc. These equipment are generally used in Africa and the Middle East.

Pulverized coal burner: gas mixed combustion burner, oil gas mixed combustion burner, gas gas mixed combustion burner, etc.
