Embodiment Construction

[0045] according to figure 1 with 2 The well gasifier is surrounded laterally and above by thermally insulating well walls 11 , 12 and is circular in cross section. The double pipe arrangement 20 extends through the shaft wall 11 on the upper end side. The double-pipe arrangement 20 includes an integrated solids conveying pipe 21 , which is connected at its upper end to a screw conveyor 30 running transversely to the longitudinal axis of the pit gasifier. The solids can be conveyed via the screw conveyor 30 from above into the solids conveying pipe 21 and fall downwards in the solids conveying pipe.

[0046] The solid delivery pipe 21 is arranged inside the pyrolysis pipe 22 . The pyrolysis tube extends farther into the interior of the well-type gasifier than the solids delivery tube 21 , so that the lower end-side opening 21 a of the solids delivery tube lies within the pyrolysis tube. The solids discharged from the lower opening 21 a fill the pyrolysis zone 23 between th...

Abstract

The invention relates to a shaft gasifier for generating combustion gas from solid material that contains carbon. The shaft gasifier comprises a shaft wall that surrounds a shaft gasifier interior and a pyrolysis zone arranged in the shaft gasifier interior, said pyrolysis zone comprising a solid material feed opening for feeding solid material that contains carbon into the shaft gasifier, a solid material discharge opening for discharging partially gasified solid material that contains carbon, and a gas discharge opening for pyrolysis gas. The shaft gasifier also comprises an oxidation zone arranged in the shaft gasifier interior, said oxidation zone being in thermal contact with the pyrolysis zone, wherein the oxidation zone comprises a gas feed opening connected to the gas discharge opening of the pyrolysis zone for discharging pyrolysis gas out of the pyrolysis zone and the oxidation zone comprises a gas discharge opening. According to the invention, the oxidation zone lies between the pyrolysis zone and the shaft wall.
