The invention belongs to the technical field of energy and environmental protection engineering, and relates to a mixed combustion and tail gas treatment integrated system based on solid-state ammonia storage. The system is composed of three core parts: firstly, a metal halide-graphene aerogel composite material is adopted as an adsorbent to realize efficient adsorption and desorption circulation of ammonia; secondly, the desorption process of ammonia is driven through engine cylinder cover water circulation; and finally, an ammonia-doped combustion technology and a tail gas treatment technology are integrated to form a complete system. Compared with the prior art, efficient storage of ammonia is achieved, the stored ammonia is used for blending combustion and tail gas treatment, emission of greenhouse gas is reduced, and a more environment-friendly and low-cost solution is provided for energy conservation and emission reduction of medium and heavy fuel vehicles.

This invention discloses a combined power cycle system and method for cooling incoming air using ammonia-water, relating to the aerospace field. The system can switch between turbine-ramjet operating modes through an adjustable structure. Particularly during turbine-ramjet switching, ammonia-water is used to cool the high-temperature incoming air in the intake duct. The absorbed ammonia-water is then distilled to separate high-temperature ammonia gas and water. This invention combines heat exchanger precooling and jet precooling, effectively increasing the pressure ratio of the fan and compressor through multiple air cooling processes. This improves the compressor outlet gas temperature, thereby reducing compressor power consumption and providing greater thrust. Ammonia, as a supplementary fuel, has a higher specific impulse, addressing the thrust gap during engine mode transitions and effectively widening the operating speed range of the turbine engine.
