引射式平焰烧嘴是一种新型煤气燃烧器。它与引射式直燃烧嘴的喷射特性有何不同,本文就此进行分析探讨。有关引射式烧嘴气体力学的文章较多,这里不作赘述。一、问题的提出众所周知,引射式直焰烧嘴具有自动比例调节特性(简称“比调”),即操作时改变喷射介质流量V_1时,喷射比V_2/V_1基本保持不变。但使用中普遍反映存在以下问题:
Buried flame burner is a new type of gas burner. What is the difference between it and the injection characteristics of the direct injection burner? This article analyzes and discusses this. There are many articles about the gas mechanics of the spout burner, so we will not go into details here. First, the problem raised It is well known that the direct injection flame burner with automatic proportional adjustment characteristics (referred to as “tone”), that is operating when changing the injection medium flow V_1, the injection ratio V_2 / V_1 basically remain unchanged. However, the use of the general reflection of the existence of the following problems:
