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.
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.
