中文摘要: 研究了燃气轮机过渡烟道内烟气的均匀性问题.通过对烟道内烟气流动的数值模拟计算,分析了出口界面的烟气流动速度,明确了烟道结构形式对烟气流动速度均匀性的影响.提出了局部阻力计算的改进方法,以期在改变燃气轮机过渡烟道的烟气均匀性的同时,也改善烟道的局部阻力.
Abstract:The uniformity of the flue gas in the duct between gas turbine and HRSG is studied. Through the numerical simulation of velocity of the flue gas is analyzed. The analysis of the velocity of flue gas helps to know the result of the velocity of flue gas in different structures of duct. The improved calculation methods of local resistance are proposed to well distribute the velocity of flue gas in gas turbine flue gas duct as well as to decrease the local resistance.
keywords: gas turbine flue duct speed uniformity local resistance
