Abstract

The invention belongs to the technical field of ammonia decomposition, and particularly relates to a supercharged engine and an ammonia fuel hybrid power generation system. The supercharged engine comprises an internal combustion engine, a membrane separation assembly and an ammonia decomposition reaction assembly, wherein first gas is compressed and then enters the membrane separation assembly, nitrogen-rich gas and oxygen-rich gas are obtained through separation, the oxygen-rich gas exchanges heat with liquid ammonia from a liquid ammonia storage tank through a vaporizer assembly, then the oxygen-rich gas enters the internal combustion engine, and the liquid ammonia exchanges heat with the oxygen-rich gas through a vaporizer and then enters the ammonia decomposition reaction assembly to be subjected to ammonia decomposition reaction; tail gas generated by the internal combustion engine enters a turbine to do work, and the turbine drives a first compressor to compress the first gas; the first gas enters the membrane separation assembly after being compressed, oxygen-nitrogen separation or hydrogen-oxygen-nitrogen separation is achieved, the oxygen-rich gas enters the internal combustion engine, and the combustion characteristic is improved; and meanwhile, the oxygen-rich gas and the liquid ammonia exchange heat in the vaporizer, the temperature of the oxygen-rich gas is reduced, the temperature of the liquid ammonia is increased, the liquid ammonia is gasified into gas, and the inflation coefficient of the internal combustion engine is increased.

Description

technical field [0001] The invention belongs to the technical field of ammonia decomposition, and in particular relates to a booster engine and an ammonia-fuel hybrid power generation system. Background technique [0002] Ammonia is not only an important inorganic chemical product, but also has unique advantages as a hydrogen carrier. Easy to liquefy, with pungent smell, high ignition point and non-toxic at low concentration, high hydrogen storage density, mature production, storage and transportation technology, and no carbon emissions in the hydrogen production process, it is an efficient, clean and safe hydrogen storage carrier . [0003] Because ammonia has a high ignition point and slow flame propagation speed in the air, it is usually necessary to mix it with other flammable fuels when using ammonia as a fuel for internal combustion engines. If only pure ammonia is used as fuel, it is usually necessary to decompose it into hydrogen and nitrogen gas or use pure oxygen...
