Learn from the best practices in the study * Brother section; there are rewards for correct answers – everyone who responds earns a reward, allowing us to grow and mature through these Q&A sessions. Brief answer: Overheating in the conical section of a melting furnace can cause serious damage to the furnace. Analyze the causes, preventive measures, and handling methods. In terms of operation procedures, it is necessary to: 1. Adjust the load gradually, without doing so too quickly. 2. Ensure that the load corresponds to the furnace pressure, or that the pressure is slightly lower than the design pressure. 3. The system must remain stable; care should be taken to maintain a consistent coal quality, ash and water quality, furnace temperature, and oxygen-to-coal ratio. 4. The amount of protective gas for the burner or the amount of central oxygen must be sufficient so that the flame can extend long enough. 5. The volatility of the coal should not be too high, in order to ensure that the temperature in the reflux zone does not become too high. 6. The thickness of the pouring material or the gaps between refractory bricks should be appropriate. 7. Impurities in the raw coal, such as weeds and plastics, must be completely removed. 8. The burner design must be reasonable, and the flow field should be stable; this is to prevent: 1. Poor slag attachment to the water wall in the upper conical section, 2. Uneven burning of the burner, 3. Changes in the burner’s flow field

The thickness of the pouring material or the gaps between refractory bricks should be appropriate. 7. Impurities in the raw coal, such as weeds and plastics, must be completely removed. 8. The burner design must be reasonable, with a stable and proper flow field, to prevent: 1. Poor slag deposition on the water wall in the upper conical section; 2. Uneven burning of the burner; 3. Changes in the burner’s flow field
