Abstract

The present invention proposes an ignition and combustion-supporting jet ammonia engine based on multiple plasma devices in the gas path, which is used for a turbojet or turbofan jet ammonia engine, including an ammonia fuel source, an air source, an ammonia decomposition box, and plasma ignition device, plasma burner, control system, exhaust waste heat recovery system, the plasma igniter is installed in the combustion chamber of turbojet or turbofan jet ammonia engine; the plasma burner is installed in the combustion chamber and air In the air inlet, the plasma burner installed in the combustion chamber includes a microwave plasma generator, and the plasma burner installed in the air inlet includes a dielectric barrier discharge device DBD; the dielectric barrier discharge device, specifically Installed at the air inlet of the air inlet, or at the rear end of the air compressor, that is, the compressed air end, the dielectric barrier discharge device includes a high-voltage electrode, a ground electrode, and a dielectric plate, and the dielectric plate is fixed on the high-voltage electrode and the dielectric plate respectively. Inside the ground electrode.

Description

technical field [0001] The invention relates to the field of turbojet or turbofan jet engines, in particular to a jet ammonia engine based on a plurality of plasma devices for ignition and combustion. Background technique [0002] Most of the current jet engines use fossil fuels for combustion, but the CO produced during the combustion of fossil fuels 2 It will cause a significant greenhouse effect, and the emission of aviation fuel contributes a considerable part of the greenhouse effect. Batteries cannot easily replace aviation fuel due to their own weight and low fuel density. To reduce the greenhouse effect, the use of new fuels to replace or partially replace existing fossil fuels is one of the only ways. As a clean energy, hydrogen energy has a stable combustion process and high calorific value released from combustion, but the Storage and transportation problems have never been effectively solved. Therefore, it is necessary to find new clean energy sources. Ammonia...
