“The “space furnace” was successfully used for lignite gasification. Author/Source: Date: 2016-03-24. Clicks: 62. Reporters learned on the 17th from the First Academy of China Aerospace Science and Technology Corporation that the Sinochem Jilin Changshan lignite chemical processing project has been successfully put into operation, with the efficiency of the gasification furnace reaching as high as 88%. This indicates that China’s first “space furnace” designed for lignite gasification has passed the relevant tests, marking a significant breakthrough in the industrial application of aerospace-based gasification technology. Lignite is the coal type with the lowest degree of coalification; it features high moisture content, high ash content, high levels of pollutants, low calorific value, and is easy to ignite and break, resulting in a very low level of industrial utilization at present. However, China possesses enormous reserves of lignite, and the rational development and full utilization of this resource are of great significance for the sustainable development of the national economy and for ensuring **energy security. The Changshan project is a typical example of the utilization of lignite. The key equipment for lignite pre-drying and lignite gasification in this project was designed and manufactured by the Aerospace Engineering Company affiliated with the First Academy. Its stable operation serves as a model for the industry, and it will make positive contributions to the coordinated development of coal energy and the environment in China. It is reported that the Aerospace Engineering Company affiliated with the First Institute has, by leveraging aerospace technology, independently developed a space-based pressurized coal gasification technology along with a complete set of related processes; this represents a **key technology for the clean utilization of coal that is being actively promoted. This technology can be widely applied in areas such as coal-based synthetic ammonia, coal-based methanol, coal-based olefins, coal-based ethylene glycol, coal-based natural gas, coal-based oil, coal-based hydrogen, and IGCC power generation. Its core equipment, the “Space Furnace,” boasts significant technical advantages, and a total of 189 invention and utility model patents have been applied for.
It is indeed the first lignite project in the aerospace sector – congratulations!
Shell gasification has been used for lignite in Inner Mongolia in China for some time now, but there are still some issues; it is hoped that the HT-L furnace will be better suited to these conditions.
Warm congratulations! The region is rich in lignite resources, with great potential
Congratulations; if it succeeds, there will be a large market
A significant increase in syngas production is desired
I would like to know more about the general process and investment costs involved in drying lignite using the HT-L gasification method in Changshan, Jilin Those who are interested in learning more please provide some information; thank you!
Is brown material dried before being gasified? I’d like to learn about this; it supports the development of coal gasification technology
Those who are familiar with this topic could please provide detailed information on the processes and precautions related to the drying and transportation of lignite. Additionally, I’m interested in knowing what effects the trace components present in coal when it is used over long periods of time can have on gasifiers or burners.
Using a space furnace to burn lignite is truly a major advancement; congratulations to SpaceTech! Personally, I think some kind of optimization or modification should be made to space-related technologies. Based on the performance of existing space furnaces, certain requirements regarding coal quality still exist. Space drying and powder feeding employ the Shell process, requiring a moisture content of ≤2%; naturally, the high moisture content in lignite can be addressed by using a drying system before grinding. Originally, the requirement for ash content in aerospace applications was 8%-12%, with a maximum of 15%. A high ash content increases the workload on the ash handling systems and can lead to issues such as pipe erosion. Moreover, the ash content in aerospace applications is relatively high; considering all this, I wonder whether there have been any improvements in components such as burners and quench chambers in aerospace technology I hope experts can help clarify this!
