中国型煤专利技术分析

Patented technologies on briquette in China

型煤技术适合中国国情,是鼓励发展和推广的洁净煤技术之一,而专利是技术发展的最好体现。对1986—2012年中国型煤相关专利进行了检索、统计、分类,分析探讨了民用型煤、锅炉型煤、造气型煤、生物质型煤、型煤黏结剂、型煤生产工艺及设备等型煤专利技术。结果表明:中国型煤技术各个时期侧重点有所不同。民用型煤在不发达地区仍有一定的市场需求;锅炉型煤推广应用较为缓慢;造气型煤是中国型煤技术研究的重点,已逐步从实验室研究向工业试验和实践生产转变,但仍有许多问题亟待解决;生物质型煤已成为中国型煤技术新的发展方向。型煤生产工艺及设备、燃用型煤锅炉等是近几年的研究热点。

To use the briquette technologies better, statistically analysed the relevant patented technologies between 1986 and 2012, which are involving briquette productive technologies and equipments for civilian use, boiler, gas making,biomass, binder and the like. The results show that, at different times, there are different promotional briquette technologies. In some underdeveloped areas, the briquette for civilian use still has broad market, the promotion of boiler briquette technology is relatively slow, the gas making technology is an emphasis, which has developed toward industrial test and actual production from laboratory studies, but there are still many problems to be solved. The biomass technologies and equipme briquette technology shows strong development momentum. The briquette productive nts, boiler are the research focuses in recent years.
