DEFINITION

Classification: 60/722

Combustion products generator:

(under subclass 39.01) Plants having a combustion device for producing products of combustion and associated parts such as valves, outlet nozzles, inlet diffusers, air compressors, air receivers, fuel pumps, fuel vaporizer, fuel injectors, igniting devices, or expansible or other chambers wherein a fuel and an oxidizer are burned in a combustion zone, and wherein the resulting products of combustion are disclosed solely for utilization in a prime mover for furnishing useful external power.
