褐煤微波脱水提质工艺研究

Experimental Research on Microwave Dehydration of Lignite

本文探索了褐煤脱水效果与微波辐射时间、微波功率、脱水煤温、脱水煤样质量之间的关系,提出了微波褐煤脱水三阶段:加速干燥、高速干燥和减速干燥阶段,各阶段特征明显。

The effects of microwave radiation time, microwave power, dehydration temperature and coal weight on lignite dehydration are explored. Three-stage theory is presented in this paper. It indicates the microwave lignite dehydration process has accelerated drying stage, high speed drying stage and decelerated drying stage, and each stage has its obvious characteristics.
