A sampling device for solids from a pressure reactor includes a housing which is connected to the reactor and accommodates a tube with its one end opening into the reactor. Movable within the tube is a sampling piston which is provided with gas-impermeable piston rings. To withdraw solids from the reactor, the piston is moved into the reactor such that the forward piston ring projects into the chamber of the reactor and is then retracted with a solids sample arranged in between the piston rings. The piston is moved to an opening of the tube so that the solids sample can be discharged to the outside.

Sampling device for solids in a pressurized reactor

Fuels, particularly caking fuels, are supplied in a fluidized bed reactor by conveying a fuel through an injection pipe with an end provided with an injection nozzle in a fluidized bed reactor, conveying a fluid through a jacket pipe surrounding the injection pipe and having an end provided with a jacket nozzle, wherein the jacket pipe is interrupted prior to the jacket nozzle, as considered in the flow direction, and at a predetermined location, and bypassing by a heat exchanger at this location at which the jacket pipe is interrupted.

Arrangement for and method of dosing fuel in fluidized bed reactor

Product gas is produced by partial gasification of coke or coal. The coke or coal is admitted in particulate form into a gasification zone where it undergoes partial gasification. The residue of coke or coal is then forwarded into a combustion zone where it is combusted to liberate heat. A gaseous heat carrier is first passed through the combustion zone to become heated therein, is then passed through the gasification zone to sustain the partial gasification process, and is then recirculated into the combustion zone to be reheated.

Production of H.sub.2 and CO-containing gases

A gas generator is provided for the production of gas from fuel and steam under conditions of high pressure and temperature. The requisite temperature is preferably provided by a nuclear reactor. The gas generator includes a cylinder wth a hollow interior. Extending transversely through the hollow interior of the cylinder is a container. Tubular heat exchangers are vertically arranged over the length, width and height of the cylinder in such a manner that the density of heating surfaces decreases along the length of the container.
