提出了一种新型的燃用煤油的微型燃气轮机低NOx燃烧室，并对原型燃烧室的燃烧特性进行了研究。为了加强一次燃烧区的回流，在一次燃烧区和二次燃烧区之间设置了一个旋流器。燃烧空气通过旋流器被引入，并被强迫向上流动到燃烧器底部，从那里燃料喷雾通过喷嘴供应。为了在较宽的燃空比下实现高燃烧稳定性和低排放，研究了一次燃烧区的优化配置。通过对稀薄燃烧极限、火焰光度、废气成分和燃气温度等基本燃烧特性的测定，找出了最佳的燃烧方式。
A new low NOx combustor for kerosene-fueled micro-gasturbine was proposed, and the combustion characteristics of prototype combustor were investigated. In order to enhance the recirculation in a primary combustion zone, a swirler was set between the primary and secondary combustion zones. Combustion air was introduced through the swirler and forced to flow upward to the combustor bottom, from where the fuel spray was supplied through a nozzle. To achieve high combustion stability and low emission in wide fuel-air ratio, the optimum configuration of the primary combustion zone were investigated. The optimum one was found out by measuring the fundamental combustion characteristics such as lean combustion limit, flame luminosity, exhaust gas composition and combustion gas temperature.
