摘要
以“中国煤种资源数据库”的数据为基础，参照“煤炭硫分分级标准”，对我国煤中硫的分布情况进行了系统的研究，并结合我国现行的各种工业用煤标准，对我国煤的硫含量进行了初步的分析和评定。结果表明，我国煤以低硫煤和超低硫煤为主，中硫煤和中低硫煤次之，高硫煤和特高硫煤所占比例很小。各大区煤中硫含量的差别较大，且有自北向南逐渐增高的趋势。我国现行工业用煤标准对硫的要求较宽松，我国大部分煤均可满足要求。为降低由燃煤而引起的硫污染，今后对高硫煤的生产应采取一定的限产措施，同时加大煤炭的入洗比例，并结合我国的技术和经济发展水平，制定出相应的控制硫污染的措施。
The distribution of sulfur in Chinese coals is systematically re-searcbed based on″The Data Bank of Chinese Coal Rank Source″and″Classification Standard for Sulfur Content in Coal.″The sulfur contents in Chinese coals are an-alysed and evaluated according to the quality standards of coal for various industries. The results show that low sulfur coal and supper low sulfur coal take a major part in Chinese coals,middle sulfur coal and middle low sulfur coal are second,high sulfur coal and supper high sulfur coal are rare. Sulfur contents in different district coals vary largely and have a trend that sulfur contents increase form North to South districts. Sulfur limits in the quality standards of coal for various indus-tries are not very strict.Most Chinese coal sulfur contents are within the limits.To decrease sulfur pollution from coal,the production of high sulfur coal should be li-mited to some extents,the production of washed coal should be increased and the regulations controlling sulfur pollution issued.
