FIELD: process engineering.
SUBSTANCE: invention relates to making the granules or briquettes from lignine-bearing material. Proposed process includes the steps that follow. Said lignine-bearing material with moisture content under 30 wt % is fed into reactor. Said material is heated to 180-235°C by steam injection into reactor for 1-12 minutes. Pressure is dropped to form processed material to granules or briquettes. Invention relates also to lignine-bearing granule or briquette used as fuel source and produced as indicated above. Besides, it relates to production of granules or briquettes from biomass. This process includes the steps that follow. Material with moisture content under 30 wt % is fed into reactor, said material is heated to 180-235°C by steam injection into reactor for at least 1 minute, pressure is dropped to form processed material to granules or briquettes.
EFFECT: better physical properties, ease of transportation and storage, higher output power of fuel combustors.
