DEFINITION

Classification: 60/39.01

(under the class definition) Plants or processes having means to generate combustion products, either continuously or intermittently, whereby said products are usable, at least in part, to perform useful work.

(1) Note. Combustion products generator a device including essentially a chamber in which a suitable fuel and an oxidizer are burned or exploded to produce hot products of combustion, together with accessory means to mix water, fuel and oxidizer, to spray or feed water, fuel, or oxidizer, to ignite the fuel charge, to periodically operate the inlet and exhaust valves, or other means accessory to such chamber.

Continuous combustion type this refers to the operation of a combustion products generator, without cyclically actuated inlet or outlet valves, in which the fuel and oxidizer are supplied to permit combustion to proceed in an unbroken or uninterrupted manner to produce a steady stream of combustion products. This type is also known as a "constant pressure" type.

Intermittent combustion type - this refers to the operation of a combustion products generator, usually having inlet or outlet valves, or both, or their equivalents, in which a fuel charge is periodically exploded or burned to discharge a pulsating stream of combustion products. This type is also known as an "explosion" or "constant volume" type.

(2) Note. This subclass and the indented subclasses include subcombinations peculiarly adapted for power production or solely disclosed for such purpose, unless classification is provided therefor in some other existing class and subclass.

(3) Note. See Lines With Other Classes in the class definition for line between Class 60 and Classes 110 and 431.

597+, for plants in which the combustion products are generated by burning a fuel in the expansible working chamber of an internal combustion engine.
