So, in order to improve the burnable efficiency and decline the latent danger, the flame burnable state detecting is needed.

所以，为了消除潜在的危险和提高燃料的燃烧效率，必须对火焰的燃烧状况进行监测。

When the CH4-air mixture approaches the lean fuel state, the flame speed accordingly decreases, the flame cone rising and retreating downstream to the area with lower flow speed.

从化学计量向贫燃料状态靠近时，预混火焰强度减弱，火焰传播速度 减小，锥形火焰面逐渐增高，退到流速较低的下游区域；

Independent security experts said the scope of its complexity and method of operation suggests Flame was sponsored by a nation-state.
