Abstract
Radiant gas cooler apparatus for treating a particulate-laden synthetic gas, which cooler includes an elongated shell. A water wall in the shell defines an annulus communicated with a pressurized purge gas source. Hot effluent introduced to the unit passes through a heat exchange chamber defined by the water wall and enters a bath in the shell lower end wherein solid material is removed. Cooled synthetic gas which leaves the bath enters the annulus to be discharged into the bath. A regulated flow of purge gas directed into the annulus prevents entry of hot effluent gas therein, precludes the accumulation of residual solid particulate matter and corrosive gaseous components, and scours the annulus surfaces. A double dip tube arrangement also protects the vessel by equalizing the pressure across an internal water wall.
