Survey on the Current Operating Status of Four-Nozzle Systems

2010-11-19View Original

Thread Content

Survey on the current operating status of four-nozzle furnaces: In addition to Texas, the four-nozzle furnaces that are currently in use include Guotai (4 years), Luhua (2 years), Linggu, SOPHOR with over a year of operation, as well as Fenghuang and Ningmei. ”This is the promotional material for the four-nozzle model. However, except for keeping Furnace A for testing, Shandong Hualu Hengsheng replaced all the others with TEXCO furnaces. This was also confirmed by Professor Shi Suiyin, who frankly stated that Shi Suiyin is not suitable for small furnaces. The Phoenix, which has been in operation for less than a year, shows significant discrepancies between its actual operational data and the theoretical values provided in the process package; moreover, issues have also arisen with the nozzles. This was revealed by people inside the organization; I also learned about it from a forum, and it seems to be true. Regarding the periods mentioned in between – “Guotai (4 years), LuHua (2 years), Linggu, and Suopu for a little over a year” – there are no specific reports available; it’s likely that their performance won’t be better than that of the newly established Phoenix. The newly installed Phoenix seems to be a large furnace; if it doesn’t work well, could it be that four nozzles aren’t suitable for large furnaces either? I hope everyone will have lively discussions! Could the companies in the middle also provide some details? This will help users understand the actual situation of the four-nozzle models and make an informed decision. !“ ”

It’s likely difficult to get the manufacturers of four-nozzle systems to provide an honest assessment, as both state-owned and private companies tend to report only the good news and hide any problems. If there are issues with the gasification furnaces in these factories, they usually try to cover them up so that everyone can maintain a good reputation. But I still hope someone can actually talk about how the gasification furnace operates, rather than just saying things like “Okay, very good” and so on. It seems that the operation of systems such as four-nozzle units, space furnaces, and even gasification furnaces using multiple types of slurries is kept secret, which is understandable – after all, who would want to expose their own shortcomings?

Looking forward to genuine reports and experience sharing from manufacturers operating with four nozzles...

I also hope to know some news on this matter

The last edit to this post was made by logo911 on 2010-11-19 at 12:54. Let me then tell you about Guotai and LuHua: Guotai’s burners have been in operation for 140 days this year, while those at LuHua have been in use for around 120 days; from the condition of the burners that were removed, it seems they are all in good condition. The operation cycle averages over 100 days. Phoenix experienced fluctuations in the early stage due to coal quality issues, but it is now operating normally; it has been in operation for almost 2 months now. This is some of the data I know.

Reply to 5# logo911: Knowing three sets of data by oneself is amazing! Are these three furnaces bigger than those in Texas? How large is the difference between the actual operational data and the theoretical values from the process package?

Hehe, I’m only responsible for the authenticity of these three companies I mentioned; I’m not too familiar with those in Texas, and it’s not convenient for me to disclose their actual operational data.

Reply to 7# logo911: Haha, ours is working well too

It is said that the 4.0MPa operation of Linggu in Jiangsu works well – does anyone who uses Linggu have anything to share? :)

The burners supplied by Beijing Aerospace for Ningxia Coal have very poor quality; often, sand holes in the oxygen weld at the center of the burners cause the furnace to have to stop operating. In one instance, a furnace ran continuously for 41 days, and after the burner was removed, it was found that the nozzle was severely worn

It is not a bad thing for someone to be aware of the operation status of three companies; this shows that there is a strong emphasis on communication among users, which leads to significant improvements both in terms of technical development and operational procedures. Besides, it’s a bit arbitrary to claim that someone’s system is having problems just because they haven’t explained its operation here Some people say that any manufacturer tends to report only the good news and hide the problems, but there’s no such thing as a wall that doesn’t leak. In this era of advanced information, I believe that if any company encounters a serious accident, most manufacturers in the industry will find out about it right away. Aside from some issues encountered by Guotai during its initial operation, have Luhua, Jiangsu Linggu, and Jiangsu Suop faced any problems since then? (I don’t have much contact with Ningmei personally.) ) The operational data differs significantly from those in the process package; I’m not sure where this information comes from. I think this person might really not have seen the actual operational data. Alas, they even forgot that one cannot speak without conducting any investigations – it’s pitiful and sad.
