Recently, there has been a lot of tar in the horizontal pipes in the basement. What could be the reason, and how can it be resolved?
It’s because the chemical product recovery isn’t good; is it that the electrostatic precipitator isn’t turned on? It’s necessary to contact the chemical production department to start up the electrostatic precipitator; that will make things better.
1. Insufficient recovery of chemical products. 2. Increase the preheating temperature of the recycled furnace gas.
What is the preheater temperature? If the temperature is too low, tar formation will occur. If the preheater temperature is normal, it’s likely a problem related to the chemical production process
Dear sea friends, what is the typical range for the preheating temperature of coke oven gas?
5# Zhou Yi 45--55 degrees Celsius
1# doudou52176: Usage of chemical process electric converters, temperature of the purified gas.
The chemical production unit doesn’t have an electric precipitator; to what extent can the initial cooler be used for regulation? The temperature of our preheater is 53 degrees
It’s getting cold; pay attention to the temperature of the gas preheater.
A pre-cooler alone is not enough; it is recommended to turn on the electric precipitator earlier, as this will definitely be beneficial for the system!
Let me tell you how to do it: remove the flange plugs at both ends of the horizontal pipe, use a 6-mm rubber hose; at one end of this hose, use an iron tube to ignite the gas and insert it into the horizontal pipe, while simultaneously blowing in compressed air (be careful with the amount of air – too much of it can blow out the flame of the gas). Using fire, it’s possible to quickly remove the tar from inside the horizontal pipe
