FIELD: power industry. ^ SUBSTANCE: solid fuel is supplied continuously to cylindrical housing 1 with screw 3 with variable pitch along the axis, and is directed to pre-compression zone 4, with simultaneous compaction and sealing of that zone. Then, fuel is supplied to oxidation and pre-heating zone 5 with temperature of 350-750C, pressure of 0-1 MPa and oxidiser inlet through branch pipe 8a, and after that, to zone of the main metered oxidation 6 with temperature of 500-1000C, pressure of 0.5-5 MPa and oxidiser inlet through branch pipe 8B, and then - to negative pressure zone 7 with temperature of 700-1500C, pressure of 0-(-0.9) MPa and oxidiser inlet through branch pipe 8c. Then, ash residue is discharged through one of connection pipes 10 in cylindrical housing 1, and exit gas with the specified physical and chemical properties - through the other connection pipe 9. Method is implemented in solid-fuel converter consisting of receiving bunker 2, cylindrical housing 1 with internal screw 3 with variable pitch and breaks in oxidation zones; oxidiser supply branch pipes 8a, 8B, 8c are made above oxidation zones, on opposite end of housing 1 there located is gas outlet branch pipe 9 with the specified characteristics with vacuum pump located inside branch pipe and ash residue outlet branch pipe 10. At that, shaft of screw 3 is hollow and meant for supply of cooling liquid and is located on bearings with tension device and made in the form of spring for elimination of deflection and for tension of shaft. ^ EFFECT: invention provides generation of heat energy, combustible gases, synthesis gas with various properties and characteristics for further conversion to liquid synthetic fuel. ^ 2 cl, 1 dwg |
