热声转换和脉动燃烧技术研究现状及其应用

A Review of Study and Application of Thermoacoustic Exchange and Pulse Combustion Technology

概要介绍热声转换机理及其在燃烧中的应用（即自激脉动燃烧），并对脉动燃烧技术的工程化应用进行了综述。实践证明，气流脉动不但能够提高传热系数，而且能提高氧化剂与燃烧剂的混合速率，大大增加燃烧强度，有利于降低燃煤时的烟尘排放，有利于保护环境。应用热声转换技术制造的脉动燃烧装置，结构最为简单。

The mechanism of thermoacoustic exchange and pulse combustion are reviewed. Some engineering applications of pulse combustion technology summarized. Pulsating combustion benefits such as intensification of burning, improves heat transfer and reduces pollution formation. The structure of pulsating combustor which used the technology of thermoacoustic exchange is the simplest.
