煤质煤质property and quality of coal煤质(Pr0Perty and quality ofcoal)既指煤炭质量，又包含煤的性质。 ·煤质指标能表征煤炭质量最基本也是最主要的指标有水分、灰分、挥发分、固定碳、硫分和发热量等几个指标。对商品煤来说，含歼率和块煤限卞率也是重要的质量指标。煤炭水分主要分全水分(也叫收到基水分，符号为Mt或五么r)、外在水分(Mf)和内在水分(厄ink沁全水分是评价煤炭质量的重要指标，其数值的大小直接影响煤炭收到基(曾叫应用基或工作基)低位发热量(Q耽，，。:)的大小，同时全水分的大小还直接影响到煤的加工、运输和使用价值。外在水分的大小主要与井下地质条件和开采工艺等因素有关。内在水分与煤的煤化程度密切相关，通常以褐煤的内在水分最高，可达30%左右;焦煤的内在水分最低，可达0.3%以一下。灰分是煤中矿物质燃烧后的残留物，一般不超过40%。灰分越高，表征煤的质量越差，当干基灰分(A户产率超过49%以后就不属于正常的煤炭产品了。灰分也是煤炭计价的重要指标。从煤炭利用角度看，灰分越低，经济效益越高，无论是用煤量或排灰量均可减少，也可减少对周围环境的污染。中国灰分最低的煤有宁夏汝箕沟的无烟煤，其灰分可达5%以下。发达国家为了降低煤的灰分，无论是炼焦煤或动力煤几乎都要经过洗选。近几年来，中国商品煤的灰分有明显下降，全国平均商品煤灰分已由21%左右降到19%左右。煤炭挥发分不仅是代表煤化度的指标，也是评价煤的燃烧、气化、炼焦、液化加氢和其他化学加工的重要参数。如机车和工业锅炉的燃煤要求挥发分(vda，)大于20%，合成氨用半水煤气的原料煤的挥发分要求低于10%，液化用煤要求挥发分30%以上的低煤化度煤等。挥发分还是估算煤炭发热量的重要参数，也是煤炭计价时的重要指标。浮煤挥发分值又是煤分类的主要指标。固定碳与硫分固定碳也是评价煤质的重要指标。合成氨用半水煤气炉用煤要求固定碳(F岛)在65%以上。煤炭硫分是煤中有害成分，硫分越高，表示煤的质量越差。煤中硫分含量的变化很大，从0.1%左右到10%以上的均有。各种工业利用对煤的硫分含量均有不同的要求。环保部门对燃煤排入大气中的502浓度也有严格的限制，超标排放的单位要罚款，严重的甚至要迁出城市。中国对炼焦用煤的硫分有严格的限制，一般干燥基硫分〔Stid)不得超过1.5%，且越低越好，个别稀缺煤种如肥煤的最高硫分也不得超过2.5%。煤的硫铁矿硫和硫酸盐硫等无机硫经过重力洗选大部可以脱除，有机硫经过洗选后很难除去，有的反而比选前的原煤更高。
