双焰燃烧器是近期出现的一种特殊燃烧装置,或叫火焰可调燃烧装置。它可以通过调节杆,将平火焰调成直火焰,又可将直火焰转回到平火焰,还能形成介于直焰和平焰之间的球形火焰。 一、工作原理和结构特点 双焰燃烧器的不同火焰形状是通过调节气流的旋流强度而得到的。 在一定条件下,气流在燃烧器喷出口处具有转向、径向和切向三个速度分量。在强旋流情况下,喷出口处不仅具有很大的切向分速度,而且气流中心轴向分速度是负值,
Double Flame Burner is a special type of combustion unit that has recently appeared, or called flare adjustable combustion unit. It can adjust the rod, the flat flame into a straight flame, but also the straight flame back to the flat flame, but also can form between the straight flame and flat flame between the flame. First, the working principle and structural characteristics The flame shape of the double flame burner is obtained by adjusting the swirling intensity of the airflow. Under certain conditions, the flow at the burner outlet has a steering, radial and tangential three velocity components. In the case of strong swirl, the outlet not only has a great tangential velocity, and axial velocity of the air stream is negative,
