Yangmei Group’s coal varieties successfully tested with ARGT gasification technology
Thread Content
From May 9 to 19, 2015, Donghua Technology Company, together with Yangmei Group, participated in the pilot gasification tests organized by the American company AEROJET ROCKETDYNE, focusing on two types of coal provided by Yangmei Group whose ash fusion points were both higher than 1500°C. Based on the test results and the discussions held after the meeting with AEROJET ROCKETDYNE and Yangmei Group, the following preliminary conclusions were drawn: (1) The ARGT gasifier performs well when dealing with coal with high ash content and high ash fusion temperature. Based on the conditions of the coarse and fine slag, it can be preliminarily concluded that coal with a high ash fusion point can undergo efficient combustion reactions in this gasifier without the addition of any solvents, thereby verifying the high-efficiency and high-temperature gasification capabilities of the ARGT gasifier. (2) Through the trial burn, the ARGT rapid mixing nozzle performed well, with no abnormalities occurring during the trial burn, achieving the expected results. (3) Through analysis of the slag deposition on the inner wall of the gasifier, it was found that the ARGT gasifier can handle coal with high ash content and high ash melting points without issues. Additionally, by monitoring the temperature of the outer wall of the gasifier, it was confirmed that the membrane-type water cooling wall design of the ARGT gasifier is adequate and capable of withstanding high-temperature gasification processes. Next, Donghua Technology will work together with Yangmei Group, in conjunction with AEROJET ROCKETDYNE, to prepare for large-scale test burns, as well as to conduct negotiations regarding contracts for industrial-scale testing facilities and carry out the preliminary preparations.

What gasification technology is ARTG? Can it withstand such a high ash fusion temperature?
Please reply promptly; if you can truly answer the question from the second floor, it would be a real blessing for all of us.
This technology was introduced in the forum; it belongs to an American defense-related company, which has been seeking partners in China for several years. http://bbs.hcbbs.com/thread-429795-1-1.html
Which expert can provide a professional analysis?
It’s probably different from Boeing’s Zeep, right? Does anyone have more detailed information on this?
In terms of operating temperature, it should be similar to the ZEEP gasifier that was promoted some time ago as having a \"leakage\" feature, or it might actually be the same as ZEEP; it seems that so-called plasma gasification was also mentioned. As everyone knows, everything remains true to its essence despite changes! In the high-temperature gasification of coal powder, the oxygen-to-coal ratio necessarily increases; the principle behind this structural change is similar to the secondary oxygen injection in the Tsinghua furnace, which raises the furnace temperature and ensures smooth slag discharge. As the gasification temperature increases, the gasification capacity naturally rises; when comparing gasification capacities at the same level, the volume of high-temperature gasifiers must be smaller. If you believe that Shell gasifiers or GSPs have reached the limits of current materials and technologies, then please pay attention to the operating cycle of ZEEP, the structure of its water wall, and the lifespan of its nozzles. In short, I have never seen ZEEP personally, but it seems to be an improvement on GSP with a higher operating temperature; if that is indeed the case, the Americans’ spirit of exploration will once again be turned into wealth in China. The above are merely my personal opinions, which contain a lot of speculative elements; they are intended as a starting point for further discussion. I hope that those who are well-informed will share some insights, so that those among us who are eager to know more can get what they’re looking for.
