Abstract (en)

Cooling and cleaning of gasified crude gas produced by the gasification of fuel, residual material and waste material comprises accelerating the gas to be cooled and cleaned from the gasification chamber in a tapering pipe to speeds of 30-150, preferably 50-100 m/s, in which a coolant is added to the crude gas before or after the narrowest cross-section. An Independent claim is also included for a device for carrying out the process comprising a Venturi pipe (3) after the gasification chamber (2) as the pipe for accelerating the gas, the Venturi pipe having openings (5, 7) for the coolant at its narrowest point. Preferred Features: The speed of the gas stream is regulated over the cross-section of the pipe independent of the amount of gas. The coolant is water, acid or base.

Abstract (de)

Die Erfindung betrifft ein Verfahren zur Kühlung und Reinigung von Vergasungsrohgasen, die bei der Vergasung von Brenn-, Rest- und Abfallstoffen entstehen und bei Normal- und höherem Druck und mit Temperaturen zwischen 1100- 1600 °C aus dem Vergasungsraum eines Flugstromvergasers in ein Kühl- oder Quenchsystem eintreten, wobei das Kühl- und Quenchsystem aus einem Vanturirohr besteht, in dessen engstem Querschnitt das zu kühlende und zu reinigende Rohgas auf Geschwindigkeiten zwischen 30 und 150 m/s beschleunigt wird und in das vor oder im engsten Querschnitt Kühlmittel zugeführt wird sowie Vorrichtungen zur Durchführung des Verfahrens. <IMAGE>
