How to solve the problem of fuel accumulation in tunnel kilns?

Tunnel kiln is a commonly used combustion equipment, widely used in the ceramic industry and other industries. During the operation of tunnel kilns, due to fuel accumulation issues, incomplete fuel combustion may occur, affecting the temperature control of the furnace and product quality. In order to solve the problem of fuel accumulation in tunnel kilns, some measures need to be taken to improve the combustion efficiency of fuel in the furnace.
Firstly, it is necessary to optimize the furnace design. By designing the structure and shape of the furnace reasonably, the fluidity of the combustion airflow can be improved and the possibility of fuel accumulation can be reduced. There should be a reasonable spatial layout and partitions inside the furnace to ensure uniform distribution and smooth flow of combustion airflow.
Secondly, it is necessary to control the combustion airflow. Reasonably adjusting the supply speed and direction of combustion airflow can avoid fuel accumulation in the furnace. By increasing or decreasing the opening of the air outlet, adjusting the speed of the combustion airflow, and setting an appropriate reaction time, the fuel can be fully burned in the furnace.

In addition, attention should be paid to fuel selection and quality control. Choose suitable fuel types and specifications to ensure fuel combustion performance and stability. Before using fuel, quality testing and screening should be carried out to reduce the impurity and moisture content of the fuel and avoid adverse effects on fuel accumulation.
In addition, it is necessary to strengthen the maintenance and cleaning of the furnace. Regularly inspect the accumulation inside the furnace and promptly remove fuel accumulation to ensure smooth combustion airflow. It is possible to eliminate accumulated fuel and ash by cleaning, flushing, and cleaning the interior of the furnace.
Need to strengthen fuel feeding control. By optimizing the fuel feeding system, ensure uniform fuel feeding and reduce the possibility of fuel accumulation. An automatic feeding system can be used to monitor the fuel supply and combustion effect in real time, and adjust the feeding speed and amount in a timely manner to ensure the stability and cleanliness of the combustion airflow.
In summary, the problem of fuel accumulation in tunnel kilns can be solved through measures such as optimizing furnace design, controlling combustion airflow, selecting and quality controlling fuels, strengthening furnace maintenance and cleaning, and strengthening fuel feeding control. The implementation of these measures can improve the combustion efficiency of tunnel kilns, reduce the risk of fuel accumulation, and thus ensure the normal operation of the furnace and the quality of products.
