FIELD: chemistry. ^ SUBSTANCE: invention relates to solid fuel gasification. A gaseous product containing CO, H2, CH4 is obtained from biomass in an apparatus 1. The apparatus 1 has a reactor 2 which is bounded by a base 5 and reactor walls. The reactor walls have a peripheral wall 10 and a top wall 11. The reactor 2 has an inlet hole 18 for feeding the biomass, a rising pipe 24 for chemical conversion of the biomass to the gaseous product. The rising pipe 24 has an upper end 28 and a lower end 26, as well as an outlet hole 44 for releasing the gaseous product. The rising pipe 24 is attached to the reactor wall 10. The base 5 of the reactor 2 consists of two lower sections 7 and 8. The lower end 26 of the rising pipe 24 lies above the lower section 8 of the base and is at such a distance from the lower section of the base 5 that it can freely move in the longitudinal direction as a result of thermal expansion. ^ EFFECT: invention reduces damage to the rising pipe as a result of thermal expansion. ^ 16 cl, 5 dwg |
