1. It is best to adjust the air volume in a small amount at a time. For example, the full amount can be adjusted in three times, with a half-hour interval between each time. This will help the layer gradually adapt.

       2. Increasing the air volume of the fan should be based on the actual situation of the material layer. During partial operation and fire, if the air volume is increased, it will aggravate the occurrence of abnormal furnace conditions. Therefore, on the one hand, the air volume should be increased, and on the other hand, the reasonable treatment of the furnace bottom should be accelerated.

       3. Ensure the minimum air volume, because if the material layer cannot achieve uniform ventilation, it is easy to cause cold operation and uneven operation.

       4. We must determine the maximum air volume, because when a gas generator gasifies a certain type of coal, it has a certain gasification intensity. For example, when Datong coal is 350kg/m2 and Huainan coal is 300kg/m2, its maximum gas production volume and maximum coal addition volume per unit time can be calculated. Our coal adding adjustment is based on detecting the height of the coal seam on the upper furnace body of the gas furnace. For mechanical automatic coal adding, the time used for the coal adding cycle can be input on the controller and appropriate adjustments can be made based on the gas generator furnace condition and gas supply volume. When it exceeds a certain range, production can be maintained, but the gas quality will decline and the furnace conditions may change, causing hot operation, so the air volume cannot be turned on too high.

       5. If the outlet pressure of the gas generator http://www.cngrjx.com is higher than the specified range, the fan air volume should be turned down. If it is lower than the specified range, the fan air volume should be increased.
