Conventional combustion can only exist within well-defined fuel to air ratios, known as the flammability limits.

常规燃烧只存在于理想的燃料空气比中，叫作可燃性界限。

As a new way of combustion, catalytic combustion breaks the flammable limits of conventional flame combustion, and realizes the combustion of ultra-natural gas/air mixture under the flammable limits.

催化燃烧作为一种新的燃烧方式，打破了传统火焰燃烧的可燃界限，实现了贫甲烷/空气混合物在可燃界限以下的燃烧，燃烧效率高，提高了能源利用率。

The experiment results show that the RSCP system has, in comparison with conventional combustion systems, outstanding behaviors, such as enhancing flame stability, and extending flammability limits.

实验结果表明，较之常规的自由火焰燃烧器，RSCP具有增强火焰稳定性、拓宽燃料可燃极限等优点。
