本文简要介绍燃技术的研究和运行中主要参教的测试方法,包括温度、某些燃气组分的浓度、粒子尺寸分布、流速等以及它们在空间的分布,着重介绍非接触式测量方法,非接触法主要是光学方法,包括光谱法与激光法,与接触法相比。它的优点是:不 干扰被测的流场和温度场,可用于温度、压力、流速较高的燃烧系统,易于实时测量,其中有些方法具有较高的空间和时间分辩率,是测量稳定和不稳定流场的有力工具,因此引起国内外广泛的兴趣和研究,获得较迅速的发展。
This paper presents a brief introduction to the research of combustion technology and the main testing methods in operation, including temperature, concentration of some gas components, particle size distribution, flow rate, etc. and their distribution in space. The non-contact measurement method is mainly introduced Contact method is mainly optical methods, including spectroscopy and laser method, compared with the contact method. It has the advantages of not interfering with the measured flow field and temperature field, and can be used in combustion systems with high temperature, pressure and flow rate for easy real-time measurement. Some of these methods have high space and time resolution and are stable in measurement and Unstable flow field of a powerful tool, which aroused widespread interest at home and abroad and research, access to more rapid development.
