Smoking while loading coal
Thread Content
In a rammed coke oven, the roof is equipped with smoke and dust removal devices. During coal loading, large amounts of yellow smoke emerge from the side doors of the furnace. What causes this smoking, and what are the most effective ways to address it?
The critical suction issue must be balanced properly
During coal loading, the walkie-talkie is used to inform the blower operator to adjust the suction level accordingly
A fake furnace door can be installed on the machine side furnace door for smoke extraction. It can be looked up online, or using on-machine focus measurement gives better results for fans. Our unit uses it
There are several reasons that can cause smoking during coal loading, and a systematic approach is needed to identify the causes. The smoke generation during coal loading has nothing to do with the furnace itself, and it is relatively easy to resolve. It is necessary to systematically investigate issues related to the suction force of high-pressure ammonia water, as well as those concerning the flue gas channels, coal bins, and the size of the coal pellets. You can contact us if you need help.
1. Check the flow rate of high-pressure ammonia water. 2. The negative pressure in the n+2 carbonization chamber is low. 3. The suction power at the floor-based dust removal station is weak
This issue needs to be analyzed based on specific circumstances. There are several reasons that can cause smoking from the furnace door on the machine side; only by examining the actual conditions on site can the cause of the smoking be determined, after which a modification plan can be developed accordingly.

This phenomenon needs to be analyzed based on specific circumstances; there are many reasons that can cause smoking from the furnace door on the machine side. Only by considering the actual conditions at each site as well as the status of the process equipment can an analysis be made.
First, analyze the source of the yellow smoke； 1. Poor coal feeding. 2. Incorrect furnace number resulting in the coal cake rubbing against the furnace wall. 3. Coal collapse during loading. 4. Insufficient height of the coal cake. 5. Coal dust falling into the carbonization chamber during loading. Solutions ； 1. Smoking occurs at the bottom of the coal-bearing floor. 2. Smoking happens where the coal touches the furnace walls. These types of smoke tend to disperse easily once they reach the upper areas, and their volume is relatively large; therefore, installing dust removal systems on the ground is necessary to address this issue. 1. Poor coal handling. 2. Insufficient coal loading height. The smoke generated can be eliminated by the suction force provided by smoke exhaust vehicles and high-pressure ammonia water. 1. Coal collapse; 2. Falling coal dust requires ground-based dust removal to be eliminated. In addition to these issues, wind direction is extremely unfavorable for eliminating smoke, so it is recommended to invest in additional ground-based dust removal systems alongside the existing ones in order to completely eliminate smoke formation.
Check the suction force in the rising pipe; if possible, use high-pressure ammonia water for smoke-free coal loading. Also, pay attention to the coordination between the coal loading vehicle and the cold drum operations.
