ABSTRACT -- III-9361773 Lyon A new form of combustion is described which if successful, will be capable of burning natural gas and other fuels which do not contain chemically bound nitrogen without any formation of NOx. The PI proposes to mitigate NOx formation and achieve much higher heat transfer rates especially in boiler applications, by carrying out combustion of natural gas using CuO as the oxidizer. CH4 will be passed over and oxidized by a heated CuO/Alumina bed. The bed is reoxidized back to CuO by air in a separate step and therefore, no direct air/CH4 reactions take place and no NOx can be formed. Furthermore since the energy producing reactions take place on a solid surface rather than in the gas phase, the heat transfer rate is much greater and the combustor can be made much smaller than the usual boiler and fire box. The proposal provides a real practical solution to the problem of NOx emission from combustion systems.

摘要-- III-9361773里昂 本发明描述了一种新的燃烧形式，如果该燃烧形式成功的话，将能够燃烧天然气和其它不含化学键合氮的燃料而不形成任何NOx。 PI建议通过使用CuO作为氧化剂进行天然气燃烧来减少NOx的形成并实现更高的传热速率，特别是在锅炉应用中。 CH 4将通过加热的CuO/氧化铝床并被氧化。该床在单独的步骤中被空气再氧化回CuO，因此，不发生直接的空气/CH 4反应，并且不形成NOx。 此外，由于产生能量的反应发生在固体表面上而不是在气相中，因此热传递速率大得多，并且燃烧器可以比通常的锅炉和火箱小得多。 该建议为燃烧系统的NOx排放问题提供了真实的实用解决方案。
