Recently, Dalian Wanyang Heavy Industry Co.
, Ltd.
and ThyssenKrupp Industrial Engineering Company (TKIS, formerly Wood Company) signed a strategic cooperation agreement on HTW (High Temperature Winkler) gasification process technology to efficiently utilize low-rank coal
.
It is understood that HTW gasification technology is widely used in lignite and other inferior coals, since the successful development by Winkler in the 20s of the last century, with the continuous improvement and upgrading of technology, it has now developed into the second generation of bubbling fluidized bed gasification technology
of high temperature and high pressure.
Coal is the main energy source in China, lignite, long-flame coal and other low-rank coal resources are abundant, accounting for more than
50% of China's coal reserves and coal production.
Low-rank coal has a high water content, low direct combustion or gasification efficiency, and existing technologies cannot fully utilize its resource value
.
Industry experts said that modern coal chemical industry should use low-grade coal, lignite, high ash coal, high sulfur coal and other inferior coal as raw materials, and coal gasification technology is the core of
modern coal chemical technology.
The German HTW technology introduced this time is a gasification process using low-grade, low-quality coal as raw material, which can not only avoid air pollution caused by direct combustion and utilization, but also greatly reduce production costs and improve resource utilization
by using low-priced three high-quality coal as raw materials.
