摘要
分析2005年和2006年经广州口岸进口的印尼动力煤的主要品质特性及其与某些影响因素的相关性,结果提示进口印尼动力煤品质不太稳定,各主要品质项目都可能出现不合格现象。全水和内水是签订贸易合同时需要首要控制的品质指标,最好能对发热量、灰分、挥发分、全硫等指标签订为干基或收到基状态,以减少贸易摩擦和纠纷。
To analyse the quality characteristics of Indonesian steam coal imported from 2005 to 2006 and the association among them and some certain impacting factors.Results showed that the qualities of Indonesian coal were lightly unstable,and the main quality items were not always fitted with the specifications.Total moisture and inherent moisture should be concerned firstly during trading or using steam coal.The best choice is to specify as dried or received for the quality items,such as calorific value,ash,volatile matter and total sulphur to decrease the risk of trading conflicts.
