<p>There is provided an efficient, economical apparatus for cooling hot gases which includes three generally cylindrical, tubular members arranged in an upstanding U-shaped configuration. The hot gases are introduced downwardly into the first leg or member of the configuration where a plurality of water nozzles provide a water boundary circumscribing the interior of the first leg to prevent thermal fatigue thereof. A water nozzle in the first member acting as a jet pump entrains the hot gases and directs them into the transverse leg or member of the configuration for rapid,turbulent cooling therein. Packed beds are provided in the second upstanding leg or member of the configuration to permit scrubbing of the cooled gases prior to exit. Coolng the gases in such a manner permits the entire configuration to be constructed of steel plate without any special insulation.</p> |
