Free space with itself quench be cooled, einmanteligem central tube.

摘要

The present invention relates to a crude gas quench system in a flight current gasification a direction for the reaction of fuels containing ash - with a gasifying medium containing free oxygen to a crude gas with a high percentage of hydrogen, in which the fuel in a gasification reactor at temperatures of 1200 to 1900°C. and process pressures of up to 10 mpa to form the raw gas and liquid slag is reacted. The quencher according to the invention has a cooling water flows to the central tube. In one embodiment, the central tube is designed as a telescoping pipe. In further embodiments, the cooling water of the central pipe is in the form of steam, as a quench water, but also as a wash water into the quenching chamber.
