Abstract
The invention discloses a wide-working-range hydrogen fuel combustion chamber. The combustion chamber comprises a gaseous fuel rotational flow injector, wherein the gaseous fuel rotational flow injector comprises a first frustum, a second frustum, a connecting pipe and a fuel pipe; the second frustum is arranged in the first frustum and is coaxially arranged with the first frustum; the top of the second frustum is of a closed structure; a feeding cavity is formed between the connecting pipe and the first frustum; an air rotational flow hole penetrating to the bottom wall of the first frustum is formed in the side wall of the first frustum; a central flow channel is formed in the second frustum; a gaseous fuel rotational flow hole penetrating to the central flow channel is formed in the side wall of the second frustum; the connecting pipe is of a conical structure; one end of the connecting pipe is connected with the top of the first frustum; and the other end of the connecting pipe is communicated with the fuel pipe. The combustion chamber is simple in structure, reasonable in design and convenient to operate, the technical effect that gaseous fuel and air are efficiently mixed to guarantee stable combustion of the combustion chamber is fully achieved, the combustion organization requirement of the gaseous fuel is effectively met, and the good market application prospect is achieved.
Description
technical field [0001] The invention relates to the technical field of combustion equipment, and more specifically relates to a hydrogen fuel combustion chamber with a wide working range and a working method thereof. Background technique [0002] At present, aviation turbine engines at home and abroad are all based on liquid hydrocarbon fuel (aviation kerosene). On this basis, according to the need to reduce emissions, some hydrogen-doped combustion schemes have been carried out, that is, hydrocarbon fuel is still used as the main fuel, and only in the combustion A part of hydrogen is added to the chamber to assist combustion, thereby improving combustion efficiency and reducing emissions, but there is currently no aero-engine technical solution that fully uses gaseous fuel. [0003] In response to the propulsion requirements of a wider speed range in the future, several power schemes based on high-efficiency pre-cooling technology have been proposed at home and abroad, such...
