为了明确西安市采暖期间燃煤中灰分和全硫质量现状，为相关部门的管理和决策提供依据，选取具有典型性的两区两县送检的煤样进行了灰分和全硫测定。测定结果表明：郊县的用煤质量远低于城区的用煤质量；但城区的用煤质量形势也相当严峻，普煤中有近1/4的煤质灰分全硫双项不达标；型煤质量更加堪忧，有近1/3的型煤灰分不达标，1/2的型煤全硫含量超标。

To have a clear understanding of ash and total sulfur content in coals used during the heating period in Xi’an city, and provide the basis for management and decision-making of environmental protection departments, ash and total sulfur content of coal samples from the city’s two districts and two suburban counties were analyzed. The results show that the coal quality of suburban counties is far below that of districts. Nevertheless, coal quality of districts is also very poor. In terms of the ash and total sulfur content, nearly one fourth of ordinary coal fails to meet the national standard. Briquettes quality is more worrying, the ash content of one third of it fails to meet the standard, and the total sulfur content of half of it fails to meet the standard.
