生物质型煤工业成型新方法及影响因素分析

A New Briquetting Method for Biomass Coal and Its Influencing Factors

针对原有生物质型煤高压成型机的局限性和不经济性 ,成功地开发了完全利用生物质纤维的交联作用实现成型的新产品 ,初步考察了煤种、成型压力、生物质形态及配比和成型水分对新方法成型性能的影响 .结果表明 :新方法对不同煤种和生物质普适性强 ;型煤机械性能随生物质配比的提高而增强 ,纯生物质成型性能优异 ,适宜的低配比为 1 5% ;能将生物质交联作用固结下来的成型压力特征值 <1 2 0MPa,过高的成型压力反而产生负面影响 ;适当调高生物质配比和降低成型压力能显著缓解水分对高压成型的不利影响 ,大同煤的许可成分高达1 0

Regarding to the limitation and low economical efficiency of conventional biomass coal briquetter determined by its briquetting method,a new briquetting mechanism using the linkage function of biomass fiber was established The effect of different coal,briquetting pressure,biomass shape and content,water content on new brequtting mechanism was studied preliminarily The results showed that the new mechanism was suitable for varied kinds coal and biomass The briquette mechanical performance was improved as biomass content increased with a reasonable low limitation of about 15% Pure biomass also could be briquetted The briquetting pressure which could consolidate the linkage of biomass fiber was no more than 120MPa There would be a negative effect at too high pressure Increasing biomass content and decreasing pressure at certain degree could offset the negative effect of water content significantly,with a permissive limitation over 10% for Datong coal
