背景技术Background technique

氨作为一种富氢化合物，易于液化，便于储存，作为燃料时，还可以在氧气中燃烧或者与含氧化合物反应，生成氮气和水，无二氧化碳排放。化学链燃烧技术，实现了燃料和空气的非混合燃烧，以氧载体代替空气，在燃料反应器中，燃料与氧载体反应，完成燃料的氧化，被还原的氧载体返回到空气反应器，与空气进行氧化反应，实现氧载体的再生。化学链燃烧技术避免了燃料与空气的直接接触，可以显著减少传统燃烧方式下氮氧化物的生成，降低了氮氧化物的处理成本。As a hydrogen-rich compound, ammonia is easy to liquefy and store. When used as a fuel, it can also be burned in oxygen or react with oxygen-containing compounds to generate nitrogen and water without carbon dioxide emissions. The chemical loop combustion technology realizes the non-mixed combustion of fuel and air, and replaces air with oxygen carrier. In the fuel reactor, the fuel reacts with the oxygen carrier to complete the oxidation of the fuel, and the reduced oxygen carrier returns to the air reactor. The air undergoes an oxidation reaction to regenerate the oxygen carrier. Chemical looping combustion technology avoids direct contact between fuel and air, can significantly reduce the generation of nitrogen oxides in traditional combustion methods, and reduces the processing cost of nitrogen oxides.

超临界二氧化碳具有能量密度大、传热效率高等特点，是环保、清洁的天然工质流体。以超临界二氧化碳为工质的发电技术也是目前国际上新型、高效的发电技术之一。Supercritical carbon dioxide has the characteristics of high energy density and high heat transfer efficiency, and is an environmentally friendly and clean natural working fluid. The power generation technology using supercritical carbon dioxide as the working medium is also one of the new and efficient power generation technologies in the world.

液氨作为我国大宗的化工产品，产量大，如果能够开发出一种基于氨燃料化学链燃烧的超临界二氧化碳发电系统，会大大降低二氧化碳排放和氮氧化物的排放。As a bulk chemical product in my country, liquid ammonia has a large output. If a supercritical carbon dioxide power generation system based on ammonia fuel chemical loop combustion can be developed, it will greatly reduce carbon dioxide emissions and nitrogen oxide emissions.
