Device for cooling hot gases

摘要

A device for cooling hot gases deriving from incomplete oxidation in a reactor and loaded with solids. A pressurized vessel (2) accommodates a refrigerator (1) made of cooled pipe-slab walls at the top and a water bath (6) for quench cooling at the bottom. A gas outlet (8) extends out of the refrigerator (1). Another gas outlet (13) extends out of the bath. The outlets can be independently blocked. The vessel also accommodates a gas-collecting section (7) upstream of the first gas outlet (8) and another gas-collecting section (12) upstream of the second gas outlet (13).
