Abstract
A process for the dry sluicing of sediment from pressurized systems, such as gasification processes, in which gravitationally conveyed sediments are cooled to below their release temperature before removal. The sediments are cooled via indirect heat exchange, such as radiation cooling, to below their release point in a first zone, and are then further cooled indirectly as well as directly via cool countercurrent gas in a second zone to temperatures below 300.degree. C., the sediment route in the second zone being lengthened by deflection of at least a part of the sediment, the sediment being removed via a sluice. The apparatus for performing the process includes a pressure resistant tank with a conical lower portion containing outlet branches, one outlet branch of which includes an externally cooled sediment conduit, the upper section of which includes straight and diagonal jacket surfaces, the bottom section including a vertical sediment shaft to which a first sluicing valve, a sluice and an additional sluicing valve are connected in sequence.
