F23R3/22 - CPC Classification

Classification description:

Continuous combustion chambers using liquid or gaseous fuel characterised by the air-flow or gas-flow configuration with devices inside the flame tube or the combustion chamber to influence the air or gas flow; Flame stabilising means, e.g. flame holders for after-burners of jet-propulsion plants movable, e.g. to an inoperative position; adjustable, e.g. self-adjusting
