FIELD: peat industry.
SUBSTANCE: method of wasteless processing of peat is accomplished by two-step heating of peat to release gaseous and solid constituents. In the first step, peat is dried to moisture content not higher than 15% using portionwise supply of peat with 350-1050 g/s portions and heating to 120±5°C, while treating and withdrawing flue gases. In the second step, solid residue is heated for 1-6 sec to 520-530° without access of oxygen. Resulting pyrolysis gas is condensed into liquid fuel.
EFFECT: optimized peat processing parameters, increased productivity of process and selectivity of peat conversion, and reduced power and materials consumption.
