摘　　要：从半焦成分、成型技术、经济性等3方面对半焦成型技术制民用燃料的可行性进行了分析。在成分方面,通过对比民用型煤现行国家标准与市售半焦产品指标,发现尽管半焦的品质会受到热解工艺、煤质、粒径等多方面因素的影响,但在发热量、全硫、挥发分指标上均能满足相应型煤的指标要求;在成型技术方面,目前多采用复合型黏结剂配合对辊成型机冷压成型技术生产半焦质民用型煤,成型产品在燃烧性能、污染物减排等方面均有良好表现,可替代散煤及无烟煤供居民日常使用;在经济性方面,在当前型煤价格体系下,无论是外购半焦末加工成型还是建立以半焦质民用型煤为主要产品的煤炭分质清洁转化项目,都具有可观的经济效益。The feasibility of using semi-coke briquette as civil fuel was analysis from three aspects,semi-coke composition,molding technology and economy.In terms of composition,by comparing the indicators of current national standards for civil briquette with that of commercially available semi-coke products,it is found out that although the quality of semi-coke can be affected by various factors such as pyrolysis process,coal quality,particle size,etc.,the calorific value,total sulfur and volatile content indexes can always meet the corresponding requirements for the briquette coal.In terms of molding technology,the compound binder is mostly used in producing civil semi-coke making in conjunction with the cold-press molding technology of roller briquetting machine.The molded product is of good performance in combustion and pollutant emissions reduction.In terms of economy,the briquette is of considerable economic benefits under the current coal price system,no matter whether it is made from purchased semi-coke powder or made by a ranked coal clean conversion project which takes semi-coke civil briquette as its main product.
