| 1. A synthesis gas cooler for extracting heat from synthesis gas produced by a gasification process, comprising:
a shell having a synthesis gas inlet and a synthesis gas outlet;
a fluid-cooled flue contained within the shell for receiving synthesis gas;
fluid-cooled radiant heat transfer surface partially extending within the flue for cooling the synthesis gas;
means for conveying the synthesis gas from the flue to the synthesis gas outlet;
quench means for injecting fluid into the synthesis gas;
seal plate means within the synthesis gas cooler for preventing synthesis gas from entering a region between the shell and
the flue; and
pressure relief means provided in the seal plate means for reducing the possibility of damage to the seal plate means which
could occur due to a pressure on one side of the seal plate means being greater than a pressure on an opposite side of the
seal plate means.
