扩散式平焰燃烧器属火道式无焰燃烧器,其火道(烧嘴砖)是燃烧器的重要组成部分,其型式直接影响火焰形状和燃烧状况。在设计燃烧器时应给予足够的重视。 一、旋转气流的状态 气流旋转能量是形成平面展开气流的动力。为了决定烧咀砖的型式,必须弄清烧咀砖形状与旋转气流的联系,分析旋转气流射流的状态参数及其分布规律。 Diffusion flat flame burner is a flue-type flameless burner, the flue (burner tile) is an important part of the burner, the type of a direct impact on the flame shape and combustion conditions. In the design of the burner should be given sufficient attention. First, the state of rotating air flow Rotating energy is the formation of a plane to start the power flow. In order to determine the type of tile burning Tsui, we must clarify the shape of burning Tsui brick and the relationship between the rotating air flow, analysis of the status of the rotating air jet flow parameters and their distribution.
