Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
151 words
A quench chamber for hot gases comprising an internal jacket formed of porous graphite and defining an internal volume and an inlet and outlet communicating with the internal volume, an external jacket encasing the internal jacket and defining two compartments between the internal and external jackets, first passage means in the internal jacket adjacent to said inlet communicating with one compartment and with the internal volume, first means to supply a cooling fluid to said one compartment for passage through said first passage means to the internal volume, with the means to supply a cooling fluid to said one compartment being longitudinally spaced from the first passage means, second passage means in the internal jacket adjacent said outlet communicating with the other compartment and with the internal volume, and second means to supply a cooling fluid to said other compartment for passage through said second passage means to the internal volume.
