乌拉盖煤田150万t/a洁净煤项目方案设计

Design of 1.5 Million t/a Clean Coal Project of Wulagai Coalfield

乌拉盖煤田褐煤储量丰富,根据该地区煤质特性可采用CCTI技术(煤脱水、中温干馏技术)设计150万t/a洁净煤项目。该技术能将低阶褐煤水分和挥发分大大降低,从而达到增加煤热值的目的,同时生成品位较好的洁净煤、焦油、燃料气等产品,明显提高低阶褐煤的清洁化利用效率。

Wulagai coalfield, with abundant lignite, can use CCTI technology （coal dewatering, medium-temperature carbonization technology） to design the projects of 1.5 million t/a clean coal according its characteristics. The technology can greatly reduced moisture and volatilizes of low- rank lignite to increase caloric value and produce high-quality clean coal, tar, fuel gas, etc. And then to improve the utilization efficiency of low- rank lignite clean.
