Discussion on gasification burners
Thread Content
Hello everyone: In light of the current issue of short lifespan of vaporization burners, we are all aware of the areas where the latest research is being conducted. How long can a good burner typically operate continuously? Thank you!
I seem to have seen this question on Haichuan Forum. The burner has a short operating life, and there is currently no perfect solution for this issue, as it is due to the special medium involved, which causes severe erosion and scouring. The 11th Aerospace Research Institute is capable of producing Texaco burners of excellent quality, which are used by many manufacturers. Generally, the inversion of a gasification furnace is carried out because of a decrease in the burner pressure difference, that is, due to significant wear. As far as I know, Texaco burners can operate for around 50 days; I’m not sure if there are any that can run even longer
For water-coal slurry gasifiers, Texaco burners typically last around 50 days, while multi-nozzle gasifier burners generally last around 80 days. Of course, the new Texaco burner from Shandong Lunan Fertilizer Factory can operate at around 150. As for the burner, its lifespan is primarily affected by the wear caused by the coal slurry and the erosion from corrosive gases in the furnace. Under certain operating conditions, the main improvement is made to the material. For burner design, research is primarily conducted from the perspectives of material and structural optimization. http://icct.ecust.edu.cn/list.php?id=45&newsid=274 Of course, it’s related to coal slurry as well
