DEFINITION

Classification: 422/198

Including heat exchanger for reaction chamber or reactants located therein:

(under subclass 129) Apparatus having means for heating or cooling the reaction chamber or the reaction mass located within the chamber.

(1) Note. Excluded from this and indented subclasses are heat-exchange means which generate a direct contact heat-exchange medium in situ (e.g., a fuel gas burner wherein the flame is produced within the reaction chamber, a catalyst bed used to generate heat via the maintenance of an autothermic reaction, etc.).
