Reactor for generating a product gas by allothermic gasification of carbonaceous raw materials

摘要

A product gas is generated from carbonaceous raw materials by allothermic gasification in a reactor. The reactor includes a pressure-charged reformer reactor for gasification of the carbonaceous raw materials, a feed line for feeding carbonaceous raw materials and ancillary materials for gasification into the reformer reactor, a combustion chamber thermally coupled to the reformer reactor for generating the heat required for the allothermic gasification, and a pneumatic conveyor device for removing particulate gasification residue and raw gas from the reformer reactor and for feeding the particulate gasification residue into the combustion chamber. A gas filter separates out the particulate gasification residue from the raw gas. The gas filter has a discharge line for product gas and discharge line for solid particles. A pressure lock has a high-pressure side and a low-pressure side. The gas filter and the pressure lock are separate components. The gas filter discharge line for solid particles is connected to the high-pressure side of the pressure lock.
