The present invention deals with a blow lance which projects into a reactor to an adjustable vertical extent. The lance structure includes a tubular lance member and a bellows surrounding the tubular lance and being expansible in the axial direction, the bellows having its lower end coupled to a lower portion of the lance and its upper end received about an upper portion of the tubular lance. The preferred structure includes a protective sleeve which surrounds a lower portion of the lance and extends into the opening of the reactor, with means being provided for circulating a coolant therethrough.

Lance for blow type reactor

A device for the gasification of carbon containing material to obtain the continuous production of gas, essentially a mixture of carbon monoxide and hydrogen, by using the molten metal bath process is provided. The carbon material, oxidizing agents, and slag-forming additives as needed are introduced into a reactor below the surface of a molten metal bath. The reactor is provided with outlets for the slag, gases, and molten metal. The reactor is also provided with the ability to tilt, swivel, or rotate about a horizontal axis. This rotational movement causes the molten metal bath to alter its location within the reactor, allowing for replacement of the input apparatus of the raw materials, which are normally below the surface, without the necessity of draining the molten metal bath from the reactor.

An apparatus for gas-tight sealing of the connection points between a stationary machine part and a machine part which is rotationally mounted with respect thereto has an annular disc disposed adjacent to the connection point on one of the machine parts, the annular disc being surrounded by an annular channeled housing which spans the connection point and is mounted on the other of the machine parts. The housing contains at least one washer or packing ring which bears against the annular ring and further includes a structure for applying pressure to the washer to maintain the washer against the ring.

In a device for the gasification of carbon and/or carbon-containing media, in particular for the continuous production of a gas essentially containing CO and H.sub.2 with a molten bath of iron or an iron alloy, a reactor receives the carbon-containing media and oxidizing gasification media under the surface of the molten bath, and outlets are provided for gas and for removing at least one liquid phase, in particular slag. The reactor is stationary and is tightly sealed to a gas outlet and to a liquid outlet. In a wall region of the reactor and close to the floor thereof a plurality of nozzles are provided for feeding the gasification media. The nozzles are distributed almost symmetrically with respect to a vertical plane which extends axially with respect to the liquid outlet and to the reactor floor about the circumference of the wall region.

Method and apparatus for cooling hot reduced material output from a reduction furnace without exposing the material to oxygen in the air. A fluid-bed-cooler which receives the heated, reduced, material from the reduction furnace contains cooling pipes through which a cooling liquid is passed for indirectly cooling the reduced material. Additionally, the cooler is connected to a positive pressure reduction gas recirculating distribution system which continually passes cooled and cleaned oxygen-free reduction gases over the heated, reduced, material to be cooled. Any losses due to leaks in the recirculating reduction system, are replaced by oxygen-free reduction gas supplied from an exhaust gas port of the reduction furnace.

Method and apparatus for the thermal treatment of slurries such as slurries of magnesite hydrate or the like. The method involves suspending the slurry in an airstream, passing the airstream with the suspended slurry particles into contact with a heated gas stream in a dryer, passing the thus-dried slurry to a multi-tiered heated kiln, introducing heated gases into the kiln for drying contact with the thus dried slurry, and passing the exhaust gases from the kiln to the dryer to serve as the heated gas stream.
