1. The bright red fire layer cannot be seen during the test of the drill. Many experienced firemen use rubber soles to gently rub the part where the fire layer is usually. If there is a wisp of smoke, it means that this part is the fire layer, indicating that the temperature is low, or the drill stays in the furnace for too short a time.
2. The fire layer is at the top of the measuring drill, indicating that the fire layer has dropped and directly contacted the grate and skirt, damaging the equipment.
3. Because the saturation temperature is too small, the reaction between water vapor and coke is weak and cannot absorb a large amount of heat. As a result, the heat released after the reaction of the oxide layer is not used in time. The accumulation of heat causes the extension of the oxide layer. An excessively long oxide layer is not conducive to the reduction reaction and has an impact on the gas quality. It can be corrected by increasing the saturation temperature.
4. The fire layer should be concentrated in a certain section. Due to frequent and excessive poking, excessive ash discharge, slagging, etc., a double oxide layer will appear. The double oxide layer is mixed with a reduction layer, making it impossible to gasify according to the normal first oxidation and then reduction procedure. The reduction time is shortened, resulting in a decrease in gas quality.
