[A new briquetting method for biomass coal and its influencing factors]

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 120 MPa. 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.
