| 摘 要： | 增压流化床燃气/蒸汽联合循环发电技术是先进的清洁用煤发电技术,而燃机叶片的腐蚀和冲蚀是应用该技术所面临的关键性问题之一。PFBC排出的烟气中既含腐蚀性物质,又携带颗粒,故叶片承受的是腐蚀、冲蚀的协同作用,称为腐蚀/冲蚀。研究表明,这两种现象有互相促进作用,因而其机理更复杂,研究难度更大,一般往往将二者分开独立研究,然而在寻找既防腐蚀又防冲蚀的材料或涂层时,

| Abstract: | The blade corrosion/erosion in gas turbine is a,crucial problem in the pressurized fluidized bed combined steam-gas cycle generation technology.This paper investigates main- ly the mechanism of erosion.The results of experiments in room temperature conclude that the erosion losses of materials are in proportion to the mass of impacting particles,the erosion rate is independent of the mass and concentration of particles,and the erosion rate is in pro- portion to the diameter of particles. |
