Abstract

A quenching chamber of an entrained-flow gasifier that gasifies fuels at temperatures of up to 1,800° C. and pressures of up to 10 MPa, wherein an annular chamber through which cooling water flows is formed between the pressure-bearing tank and the inner jacket. The overflow water is discharged from the annular chamber (skirt water) into the quenching chamber via the sleeve of a quenching lance, wherein blocking by the spray cone of the spray nozzle is prevented. The cooling water from the annular chamber is used in addition to the quenching water from the spray nozzle to cool and clean the raw gas in the quenching chamber.
