Abstract: 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 briquette technology shows strong development momentum.The briquette productive technologies and equipments,boiler are the research focuses in recent years.
