Synthetic gas radiant cooler with internal quenching and purging facilities
A radiant syngas cooler is described for treating a stream of hot, particulate-containing synthesis gas effluent, which cooler comprises an elongated upright shell, a water bath at the shell lower end, a first dip tube depending from said shell and defining a disengagement zone at the shell lower end above said water bath, a water wall extending internally of said shell forming an internal chamber and being spaced from the inner wall of said shell to define an elongated annulus there between, inlet means in said shell communicated with said internal chamber to conduct said stream of hot particulate containing syngas thereto, a second dip tube depending from said water wall, spaced inwardly of said first dip tube to define a constricted annulus there between which terminates in said water bath, flow control means for communicating said annulus with a pressurized source of a purge gas, whereby said purge gas and said particulate-carrying synthesis gas will enter said bath concurrently, and at least one gas discharge port communicated with said disengagement zone to conduct cooled gas therefrom.
