摘要
褐煤水含量较高,限制了褐煤的应用范围。褐煤的脱水干燥是褐煤提质的关键步骤。文中综述了不同的褐煤干燥技术,并对其相对优点和局限性进行了讨论。
The application of lignite is limited due to its high moisture content thus the lignite drying process is the key step for lignite upgrading. In this paper, various lignite drying technologies are reviewed, and their relative merits and limitations are also summarized and discussed.
