Coal gas oil firing clay brick production Tunnel Kiln

Target Industries & Applications: Brick manufacturing, ceramic production, construction materials.

1. A tunnel kiln typically consists of the following main parts:
2. (1) The main structural part of the tunnel kiln, usually an elongated passage with tracks or rollers inside to support and move the green bricks.
3. (2) The first zone that the green bricks enter after entering the kiln body, where the temperature gradually increases to remove moisture from the bricks.
4. Firing Zone: The core area of the tunnel kiln, with the highest temperature, where the bricks are sintered.
5. Cooling Zone: The zone where the fired bricks are cooled down gradually to a temperature suitable for unloading.
6. Combustion System: Provides the heat required for firing, usually including burners, fuel supply systems, and exhaust systems.
7. Ventilation System: Controls the airflow inside the kiln to ensure complete combustion and uniform temperature distribution.
8. Drive System: Used to move the green bricks through the kiln, usually including motors, chain drives, or roller drive devices.

1. To ensure the efficient operation and long service life of tunnel kilns, regular maintenance and care are necessary:
2. Regularly inspect the kiln body for cracks, deformations, or other damage, and repair them in a timely manner.
3. Clean the combustion system regularly, including burners and fuel supply systems, to ensure complete combustion.
4. Ensure that the ventilation ducts are unobstructed and check the normal operation of fans.
5. Inspect the operation of the drive system, including motors, chains, or roller drives, and lubricate and replace worn parts in a timely manner.
6. Regularly calibrate temperature sensors and control systems to ensure accurate temperature control.
