Recently, a lot of naphthalene has often appeared on the fire adjustment plate. What’s going on?

Is it due to the preheater temperature? This post was last edited by ryn on 2009-2-18 15:55]
Where can I get an orifice plate? On the coal gas pipeline for reheating? Explain the problem clearly so others can help you
If the gas purification is not adequate, even by raising the preheater temperature to over 50, other gas heating components will still get clogged, not to mention the branch pipes.
It’s mainly due to poor gas purification; check the chemical production process
If there is an excess of tar and naphthalene, and this is the case for many units in the entire furnace, then it’s a problem related to the purification of chemical products
Check the gas; there might be issues with the gas, and the preheater also needs to be checked
Gas preheating is one aspect; the other aspect is the issue of gas purification. If the removal of naphthalene is not effective, it can also lead to the accumulation of naphthalene on the orifice plates.
What are the densities of tar and naphthalene respectively? Is the viscosity of tar related to its naphthalene content?
If it’s the last few ovens in the coke oven bank, it’s due to too low a gas temperature; in such cases, the gas temperature can be increased to 55 degrees. If it affects all the ovens, then it’s a problem related to chemical processes, and this needs to be addressed promptly, otherwise the workers involved could lose their jobs
Chemical production is the main problem; our factory has encountered this issue, and it needs to be resolved immediately. The consequences are severe. Hurry. . . . . . . . . . .
Stop heating as soon as possible and clean with steam. And conduct gas analysis promptly; it seems there is a problem with the crude benzene
The gas purification is not good! ! The preheater temperature can be increased a bit! ! !
Check the gas temperature after the primary cooler; if it is high, find a way to lower it. Also, is the gas temperature low after the preheater?
