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

A method and an apparatus are disclosed for classifying particulate substances. A mix of heavier and lighter particles is confined between upwardly divergent side walls and a fluidizing gas is blown into the mix from below. A conveying conduit is arranged below the sidewalls and has vertical conduit portions which have upper open ends communicating with the space between the sidewalls. A classifying gas is blown through the conduit and the conduit portions at a pressure which is higher than that of the fluidizing gas to keep the lighter particles from entering the upper open ends, but which is sufficiently low so that the heavier particles can overcome the pressure of the classifying gas and drop through the upper open ends into the conveying conduit from which they are periodically expelled by bursts of a transporting gas.
