1. Increase the intensity of blowing. Increasing the blowing intensity can not only increase the reaction speed, shorten the blowing time, and increase the effective gas production time, but also inhibit the occurrence of side reactions and reduce consumption.

       2. Reasonably control the upstream and downstream temperatures to improve gasification quality. The level of the upstream and downstream temperatures can indirectly reflect the condition of the gasification layer in the furnace. If the temperature is too high, the heat loss will be large and scarring will occur easily. If the temperature is too low, the temperature of the gasification layer will be low and the gasification quality will be poor. Only when the upstream and downstream temperatures are properly controlled can a thicker gasification layer be obtained and the gasification quality be improved.

       
       3. Reduce system resistance and reasonably control steam pressure entering the furnace. In the process of gas production, lowering the pressure will help the reaction proceed in the direction of generating carbon monoxide, and high-quality semi-water gas can be produced.

       4. Increase the height of the carbon layer appropriately. The height of the carbon layer is mainly determined based on the intensity of the blowing. Appropriately increasing the height of the carbon layer can increase the steam decomposition rate and improve the gas quality. However, it should be adjusted in time according to the intensity of the blowing. According to the experience of relevant units, when the intensity of the blowing is high, the general air travel height is controlled at about 1.7 to 2.0m.
