Unmixed Combustion

描述了一种新的燃烧形式，如果成功，将能够燃烧天然气和其他不含化学结合氮的燃料，而不会形成任何氮氧化物。PI建议通过使用CuO作为氧化剂进行天然气燃烧，以减少NOx的形成并实现更高的传热率，特别是在锅炉应用中。CH4将通过加热的CuO/氧化铝床被氧化。床层在一个单独的步骤中被空气再氧化回CuO，因此不会发生直接的空气/CH4反应，也不会形成NOx。此外，由于产生能量的反应发生在固体表面而不是气相，因此传热速率要大得多，而且燃烧器可以做得比通常的锅炉和火箱小得多。该方案为解决燃烧系统NOx排放问题提供了一个切实可行的解决方案。

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.
