| 摘 要： | 煤中全水分是炼焦精煤中一项重要的计价指标，中国动力用煤采用收到基低位发热量计价，每增加1％的全水分将会使发热量降低260J／g左右。准确测定煤中全水分，可减少煤炭供需双方的质量纠纷，使煤炭按质计价更科学、公正、公平，在煤炭按质计价中起到举足轻重的作用。根据多年的实践经验，提出准确测定煤中全水分可行的操作方法，以避免煤炭供需双方产生不必要的质量争议。

| Abstract: | The total moisture in coal is one of the most important valuation indicators for coking coal. The steam coal is evaluated by the low heating value of received basis. A 1 percent increase in total moisture would decrease about calorific value 260 J/g. The accurate determination of total moisture can reduce the quality dispute between supply and requisitioning parties and make the coal valuation more scientific and fair. Through many years＇ practice, provide feasible operating methods for the evaluation of steam coal. |
