摘要
Entrained flow gasifier for obtaining energy for generating steam from the sensible heat of the hot gasification gas and the molten ash molten to fuel slag in which - a reaction space (1) for gasification feinaufgemahlener, ash-containing fuels in the air flow at gasification temperatures above the ash melting point is given, - Reaction space at the lower end via a slag exhaust body (2) in a quench (3) for partial quenching of hot Gasgasgasgasgas and liquid slag by means of coolant (4) to temperatures of approximately 900 ° C, - a Quenchraum enclosing annular channel (7) for guiding the partially quenched Vergasungsrohgases is arranged upwards, - a water bath for receiving slag, which extends over the diameter of the annular channel, is arranged below the Quenchraumes, - a ring channel enclosing waste heat boiler (10) for guiding the teilgequenchten Vergasungsrohgases after is arranged below.
