How is the two-stage dry powder furnace at Inner Mongolia Shilin Chemical Co., Ltd.?

The two-stage dry powder furnace is a new type of gasification furnace developed by Xi’an Thermal Power Institute in China; according to available data, its performance is even better than that of Shell’s furnaces. A 1,000 tons/day furnace with a quenching process has already been used in Inner Mongolia Shilin Chemical Co., Ltd.’s project to produce 300,000 tons of methanol per year, and it is expected to come online in 2008. Another 2,000 tons of fluidized bed boilers for IGCC are used in Huaneng Group’s green coal power projects. As people in the chemical industry, we’re all interested in the quenching process – I wonder how this project is progressing It’s already the second half of 2009 – has it been launched yet? How is it running? Those who know about this, please share some information.
1# hjy2000 It’s still too early; if we can test drive by this time next year, that will be great.
What’s the problem? Without revealing any secrets, I’ll briefly explain things so that everyone can understand more about the situation. Thank you.
The installation of the 3 units of 75-ton boilers has been completed. For the other installations, the civil engineering work is now finished, and the equipment installation phase has begun.
The technical level of two-stage dry powder furnaces doesn’t seem to be as complicated as what the original poster said. The two projects that plan to adopt this technology have just started, and we will have to wait and see how successful they prove to be. An insider in the power industry said that Huaneng’s Tianjin green coal power project is more hype than actual action. The Old Drunkard’s real intention isn’t IGCC!
We are currently training the employees; the drawings have not arrived yet. Gasification civil works for 32 meters are completed; installation will begin next year
It’s too early; it definitely won’t be able to start this year. I’m not even aware of what stage the project is at
I heard that many more drawings are still missing, and it’s uncertain when production will start!
I just visited Shilin. The construction site for Phase 1 is in full swing; the steam boiler plant, cooling towers, as well as the main structures for gasification, double dehydration, methanol synthesis, and distillation have been built. The main air separation plant and main control room are also completed. Many equipment foundations have been poured, the distillation equipment has arrived at the site, and the methanol storage area has been constructed and painted. However, the main equipment for gasification, purification, and methanol synthesis was not present on site. I’m not sure if the delivery date for the key equipment will be on time There is a relative shortage of professional and technical personnel; at first glance, it seems unlikely that production can start within a year or so. Of course, it’s possible that it depends on human effort. As for the gasifier in its rapid cooling process, compared to the Shell gasifiers that are already in use, it should be able to avoid certain problems: most of the Shell gasifiers in mainland China have experienced shutdowns due to slag buildup, as well as issues with ash accumulation in the reactors. The Shenhua coal-to-oil Shell gasifier, which uses stable coal from the mine entrance as raw material, has hardly experienced any shutdowns due to slag blockage in the gasifier since it came online in April 2008; the only issues encountered have been ash accumulation in the waste boiler and failures of the S1501 unit. The Shell gasifier used in the divinized coal-to-oil process does not suffer from slag clogging, and objectively this is mainly attributed to its stable and high-quality coal supply. The two-stage rapid cooling gasifier uses the same raw coal as that in advanced coal-to-oil processes, and it will not be plagued by slag clogging issues. Since there is no waste boiler system or S1501 unit, there is also no problem of ash accumulation. By drawing parallels from the operation of the shell gasifiers used in advanced coal-to-oil processes, it can be said that the Shilin rapid cooling gasifier will, at least, eliminate the two major operational problems of slag clogging in the gasifier and ash accumulation in the waste boiler. As for other issues, powder preparation and transportation, as well as the slag treatment system, are essentially reorganizations of those used in powder gasification and water-coal slurry gasification; there should be no significant problems, with the key lying in the design of the five-ring system. Therefore, the future operation of this device is promising.
According to a friend from Hangzhou Boiler, the delivery date for the gasification furnace is scheduled for the end of February next year. However, due to slight delays in the procurement of some materials, efforts are still being made to have the equipment arrive at the site by the end of February. It is said that Shilin is pressing for this timeline, aiming to complete the installation and start testing before construction begins next year
It’s October 8, 2011 now. I’m not sure what the situation is like these days. Does anyone know and can share it with us?
