据1991年6月号报导,苏联全苏热工研究所正积极研究在动力工程领域内应用燃气轮机。其主要的科研方向是科学地保障燃气轮机装置可靠地运行并研制新的燃气轮机机组,其中包括研究高性能的燃烧室和燃气涡轮叶片的冷却。燃气轮机燃烧室的研究方向着重于保证长期运行的可靠性和经济性并减少向周围环境的污染排放。文章介绍了—150型燃气轮机装置的组合式燃烧室,它由外侧环形微焰燃烧器和中心的扩散火焰燃烧器组成。在以气态燃料和液态燃料作为燃料时,上述燃烧室可使氮化物浓度减少50%到60%。由于是微焰燃烧,可使火焰长度缩短33%到50%、壁面金属的最大
According to a June 1991 report, the Soviet Union Thermal Research Institute is actively studying the use of gas turbines in the field of power engineering. Its main research direction is to scientifically ensure the reliable operation of gas turbine installations and the development of new gas turbine units, including cooling of high performance combustion chambers and gas turbine blades. Gas turbine combustor research focuses on ensuring long-term reliability and economy and reducing emissions to the surrounding environment. This paper introduces the combined combustion chamber of a -150 gas turbine unit, which consists of an outer ring-shaped micro-flame burner and a central diffusion flame burner. The above combustion chamber can reduce the nitride concentration by 50% to 60% when using gaseous fuel and liquid fuel as fuel. Because it is a micro-flame combustion, the flame length can be shortened 33% to 50%, the maximum wall metal
