Air leakage from the grating of the boiling furnace causes frequent shutdowns of the equipment
Thread Content
During the production process in a boiling furnace, due to a gap between the refractory bricks on the side walls and the ceiling panel, coupled with the erosion caused by the material, gases at the bottom of the furnace escape through this gap. As a result, the gas inside the air caps loses pressure, and the material tends to accumulate on the air caps of the furnace, which can easily lead to a \"dead furnace\" situation. Such problems can be discussed together.
To address the problems caused by air leakage at the grating of the boiling furnace, a feasible solution is to inspect and repair the gaps between the refractory bricks and the grating. Such gaps usually result from the damage or deformation of refractory bricks caused by prolonged high temperatures and material erosion. Here are some steps and suggestions: 1. **Inspect and assess the gaps**: First, it is necessary to thoroughly inspect the gaps between the refractory bricks on the side walls of the furnace and the ceiling tiles, in order to evaluate the size of these gaps as well as the extent of any damage. 2. **Select the appropriate filling material**: Choose a high-temperature resistant filling material suitable for the characteristics of the gap. Common filling materials include refractory mortar and high-temperature resistant sealants. 3. **Fill gaps**: Use the selected filling material to fill and seal the gaps. Ensure even filling with no gaps, in order to restore airtightness between the refractory bricks and the ceiling panels. 4. **Testing and Monitoring**: After the repairs are completed, conduct a limited-scale trial operation to check whether the repair results meet the expected standards and to ensure that there are no gas leaks. 5. **Regular Maintenance**: Establish a schedule for regular inspections and maintenance to monitor the condition of the refractory bricks and ceiling panels, and address any new gaps or damages that may arise promptly. By following these steps, gas leaks can be effectively reduced, the normal operation of the boiling furnace can be restored, and problems such as frequent shutdowns and a \"dead furnace\" can be avoided. If there are more specific details or other questions, we can explore solutions further. .
This phenomenon has never occurred to us.
To ensure the free expansion of the ceiling, it is supported slidably on the underlying structure. There is a flexible sealed welding strip between the flower plate and the shell. In this case, it is either because the sealing strip has not been welded or because the weld has failed and air is leaking. Remove the refractory bricks, weld the seal strip back in place, and then reinstall the refractory bricks.
There are gaps in the sidewalls of the fluidized bed furnace, making repairs difficult. The welds between the perforated plates or between the perforated plates and the furnace walls are not airtight, resulting in air leakage. By using the patented plug-in air cap from our Shandong Qianda Company, and conducting regular inspections, smooth operation of the large furnace can be ensured
