Problems solved by technology

Although these methods can achieve high overall efficiencies at the beginning of the operating time, they have the additional disadvantage of reducing the availability of the gasification plant due to ash and soot deposits, increasing the Maintenance costs, so the added advantage of getting steam more than compensates for the resulting disadvantage

Embodiment Construction

[0028] Embodiments relate to the use of the invention in a coal dust pressure gasifier with an integrated quench system. Gasifier efficiency is 80,000m under standard conditions 3 / h, dry basis.

[0029] The cooling and quenching vessel 13 arranged immediately below the gasification reactor is divided into a transient quenching chamber 1 and a main quenching chamber 2 . The gas inlet 14 (here: the slag discharge body of the gasifier) ​​has a diameter of 600 mm and a height of 1000 mm. On the upper side of the inner side of the cylindrical instantaneous quenching chamber 1 with a diameter of 800mm, the water supply facility 3 is loaded through the water ring chamber for 40m 3 / h of water, so that a closed water film 4 flowing downwards is formed on the inside of the instantaneous quench chamber. The actual quenching of the gas stream passes through 3 nozzle rings 5 ​​each of 30 m 3 / h, the nozzle rings 5 ​​are each equipped with 8 individual nozzles. The housing of the tra...

Abstract

The invention relates to a process and a device for the treatment of charged hot gas, in particular hot pressure gasification gases from fly stream gasifiers during the partial oxidation of dust-type and / or liquid ash-containing feed in the fly stream.

Description

technical field [0001] The invention relates to a method and a plant for the treatment of loaded hot gases, preferably in connection with the production of CO-containing and h 2 gas, wherein the laden hot gas, in particular containing slag and solids, is conveyed from the reaction chamber into an attached cooling / quenching vessel, the solids and gases are separated, and discharged from the cooling / quenching vessel gas. The invention also relates to the use of the device according to the invention. Background technique [0002] For discharging hot gas laden with liquid slag from the reaction chamber into an underlying cooling chamber, DD 145860, DD 299893, EP 127878 and DE 3151483 propose introducing this laden gas stream directly into a water bath via a cooled dip tube. This functional principle has not proven to be successful in practice, since only short trouble-free operating times are achieved, and the outlay for repair and maintenance is considerable. [0003] In t...
