Causes and solutions for raw material ignition in bentonite dryer

1. Incomplete fuel combustion. If the fuel fails to burn fully during the combustion process, the unburned fuel may continue to burn at the tail of the dryer, causing local overtemperature. To ensure that the fuel is fully burned, it can be achieved by adjusting the burner and the amount of combustion air.

2. Improper fuel quality control. Non-standard fuel is used, resulting in unstable combustion. Use fuel that meets the standards and check the quality of the fuel regularly. If the equipment capacity is insufficient, consider replacing a larger dryer or increasing the number of dryers.

3. Equipment specifications do not match demand. The bentonite dryer has too small a capacity and handles too much material. In order to achieve the drying effect, the temperature is forcibly increased, causing fire. Contact the manufacturer and request improvements or replacements to the equipment to improve the thermal efficiency and safety of the equipment.

4. The moisture content of the raw material is too high. High-humidity raw materials are prone to spontaneous combustion at high temperatures. For high-humidity raw materials, pre-drying can be performed to reduce the risk of fire.
