20110100274CONTINUOUS FUEL SUPPLY FOR A COAL GASIFICATION REACTOR - A facility for the continuous supply of a coal gasification plant with finely ground fuel material is disclosed. The fuel is first stored in a storage tank and then fed to a lock hopper system, where it is supplied with gas for the coal gasification reaction. The lock hopper system consists of at least two lock hoppers to achieve that the gas is injected quasi-continuously, and the fuel is then passed to a feed tank in which a constant filling level prevails over a given period of time, so that the fuel is conveyed in a constant, smooth and pressurised flow from this feed tank to the burners.

20110183276DEVICE AND METHOD FOR THE DEGASSING OF DUSTS - An apparatus for the degassing of a dust from a synthesis gas produced by a gasification process, is disclosed. The apparatus comprises a main dust separator, a multi-purpose vessel, fluid for degassing and cooling and a storage facility for dust. The synthesis gas produced is conducted via a connecting pipe to a main dust separator, from which a de-dusted raw synthesis gas stream and a dust-like solid which also contains raw synthesis gas in the voids between the dust particles can be removed. The dust-like solid is directed into a multi-purpose vessel equipped with devices for reducing the pressure level so that a tail gas is obtained and a solid containing lower gas quantities in the void fraction remains. There is a device for transporting a solid into a gas exchange apparatus, the latter comprising a gas exchange tank, a dust separator and a feed device for exchange gas. It is possible to reduce the gas exchange tank to atmospheric pressure. The gas exchange apparatus has an outlet for a solid that has been at least partially liberated from raw synthesis gas, said apparatus having an upwards-oriented conveyor in which an upwards-directed gas and solids stream can be established. The conveyor has an open cross-section, a bottom clear opening and a top clear opening. A feed device for exchange gas which is directed into the bottom clear opening is positioned underneath the bottom end of the conveyor. The dust separator has a discharge device for a tail gas stream and a downwards-directed connection into the gas exchange tank for a solid liberated from raw synthesis gas.07-28-2011
