  • Patent number: 4818253
    Abstract: The gasification device includes a pipe wall structure assembled of a plurality of pipe circuits enclosing in a gas tight manner a reactor space. A pressure jacket surrounds at a distance the pipe wall structure and delimits therewith a water filled interspace. All inlet conduits for supplying cooling water to individual pipe circuits pass through the jacket whereas the outlets of the pipe circuits open into the interspace. A common discharge conduit for cooling water is provided in the pressure jacket and communicates with the interspace. The pressure jacket is assembled of two parts interconnected by a releasable flange connection. All inlet conduits and common outlet conduits are attached to the upper part so as to enable the lifting of the entire pipe wall structure upon the lower part together with the upper part.

  • Patent number: 4731097
    Abstract: A device for cooling a stream of hot producer gas exiting from a gasification reactor operating at an increased pressure, includes a set of water spraying nozzles directed against the producer gas stream. Water feeding conduits connected to the nozzles pass through a sealing web provided between the pipe wall structure of the reactor and a separate pipe wall structure of a gas outlet connection piece provided above the discharge opening of the reactor. The geometric locations of respective nozzles are on a circle whose diameter is larger than that of the gas discharge opening and is smaller than the inner diameter of the pipe wall structure of the connection piece.

  • Patent number: 4617988
    Abstract: A soot blower for the removal of deposits collected on the surfaces of walls forming a chamber, through which gases containing solid particles flow, is integrated in one of the walls which form that chamber. The feeding pipes of the blower for feeding a blowing agent into the chamber are formed in the region of the line which defines the outer face of that wall.
