Development of modification technology of wood raw material in production of solid biofuel

Studies have shown that the mechanical properties of the pellets produced from hardwoods yield pellets traditionally used pine. In order to improve their original wood raw material modified by the addition of protein nature (albumin, casein , gelatin) and starch (potato starch and maize, starch syrup) by spraying through nozzles in the screw feeder directly before granulation. To increase the strength of pellets application proteinaceous adhesives has proved more effective than the starch paste. Albumin as presented in this particular interest. To carry out industrial testing technology was developed modifications of chopped wood with its use in the production of pellets. The tests samples of modified wood pellets showed full compliance with them as a group 1 (in STB 2027). Humidity pellets was 10%, ash content – 0.7%, the wood dust abrasion – 0.8%; calorific value – 17,640 kJ/kg
