Based on analyzing the sulfur content and its distrib ution of Xishan coal, the feasibility and necessity of three desulfurization met hods were studied. 根据对西山高硫煤的硫含量及分布的初步分析，研究了多种脱硫方法的可行性。
Only washed coal or high quality and low sulfur content coal can be allowed to directly use by boilers for space heating and production. 对于采暖及生产锅炉直接燃煤，必须使用优质低硫煤或经洗选的煤炭。
