Description
F23R covers combustion chambers and apparatus designed to generate high-pressure or high-velocity combustion products, particularly those used in gas turbines, jet engines, and similar applications requiring rapid gas expansion and discharge. This subclass includes the design, construction, and operation of combustion systems that produce intense thermal energy and directional flow suitable for powering turbomachinery. Technologies encompassed include fuel injection systems, flame stabilization mechanisms, combustor liners, and thermal management strategies specific to high-performance combustion environments. Related adjacent classes cover general combustion apparatus (F23B–F23Q) and specific combustion process details, while F23R focuses on the chamber and system architecture necessary for generating elevated pressure or velocity conditions.
Scope Notes
Glossary: Flame tube flame tubes The portion of a combustion chamber downstream of the zone where fuel and primary air are mixed. | Limiting references: Fluidised bed combustion chambers specially adapted for operation at superatmospheric pressures | Application references: Combined gas-turbine and steam-turbine plants Gas-turbine plants e.g. , Combustion-product positive-displacement engine plants Jet-propulsion plants e.g. Combustion chambers for rocket engine plants, i.e. plants carrying both fuel and oxidant therefor Starting of engines by supplying pressure fluid generated directly by combustion
