Matters needing attention when re-igniting the kiln

After a period of inactivity, the kiln has gradually cooled down, and the system parameters on the kiln have gradually become a state that needs to be reset. At this time, although the kiln's state parameters are different from those of a new kiln, they are already in a "zero" state. When using the kiln again, it needs to be reignited. So what should be paid attention to when reigniting? Different kilns should be handled differently.

1. Precautions for reigniting tunnel kilns. For tunnel kilns, since most of the interior is built with refractory materials during construction, when the kiln is shut down for a period of time and restarted, the various systems and settings on the kiln should be readjusted, and the kiln should be heated according to the properties of the refractory materials, gradually raising the kiln temperature to the normal operating temperature.

1.1 Inspection of the kiln during reignition When reigniting a tunnel kiln, a detailed inspection of the kiln system, various equipment, and facilities should be carried out to provide sufficient conditions for ignition.

1.1.1 Check the kiln bottom cooling system The tunnel kiln kiln bottom cooling system is a system specially designed for tunnel kiln tracks and kilns. It can lower the temperature under the kiln car, minimizing the thermal expansion length of the kiln car track, and cooling the kiln car to minimize thermal deformation.

1.1.2 Check the kiln car running system The main function of the kiln car running system is to ensure that the kiln car not only runs normally in the kiln, but also that the running system outside the kiln can achieve the normal operation of the entire production line, so that the brick unloading section can unload the bricks in time, and the empty kiln car can be quickly sent to the brick stacking area. The kiln car with stacked bricks can be sent to the drying room or tunnel kiln at the necessary time.

1.1.3 Check the kiln ventilation system The ventilation system is very important for kiln firing operations. The kiln temperature and temperature uniformity depend on the ventilation capacity and air distribution. The firing process is an energy exchange process and a wet heat exchange process, which are achieved by adjusting the air volume of the kiln ventilation system.

1.1.4 Check the kiln detection and control facilities The kiln detection and control facilities are key components for monitoring the kiln temperature and pressure systems and the temperature distribution in the kiln. It allows us to grasp the actual situation of kiln firing and provides basic and real data for controlling kiln firing.
