FUEL BRIQUETTE FABRICATION PROCESS

FIELD: solid fuel production. ^ SUBSTANCE: invention relates to coal processing industry, namely to brown coal briquetting technology in order to fabricate agglomerated solid fuel that could be used for community needs as well as in industry. Idea of proposed fuel briquette fabrication process resides in grinding brown coal, measuring it out for mixing with sawdust, and briquetting mixture. Mixture of brown coal having particle size below 2.5 mm and softwood sawdust is prepared without binder. At content of sawdust 17±1%, briquetting temperature 90±5°C, and specific briquetting pressure 50±2 MPa, briquettes showing compression strength at least 7.8 MPa. ^ EFFECT: increased mechanical strength of briquettes. ^ 1 dwg, 1 tbl
