    • PURPOSE: A combustion coating method in driving of a gas turbine is provided to minimize thermal stress between a silica coating layer and a heat shield coating layer and to improve durability of the existing heat shield coating layer with the additional silica coating. CONSTITUTION: A gas turbine is operated so that driving is started at predetermined speed and predetermined temperature(S110). A predetermined silica coating agent is supplied to a fuel of the gas turbine(S120). The supplied silica coating agent is combusted so that components touching combustion gas in the gas turbine are coated(S130). The gas turbine is operated for fixed periods after coating agent supply to a fuel line is stopped(S140). [Reference numerals] (S110) Drive a gas turbine to start an operation at predetermined speed and temperature; (S120) Supply a predetermined silica coating agent to fuel of the gas turbine; (S130) Coat a part of the gas turbine with the silica coating agent; (S140) Stop the supply of the silica coating agent to the fuel line after a predetermine time and operate the gas turbine for a predetermine period of time
    • 目的:提供燃气轮机的燃烧涂覆方法,以最小化二氧化硅涂层和隔热涂层之间的热应力,并提高现有隔热涂层与附加二氧化硅涂层的耐久性。 构成:运行燃气轮机,使得以预定速度和预定温度开始驾驶(S110)。 向燃气轮机的燃料供给规定的二氧化硅被覆剂(S120)。 所供应的二氧化硅涂层剂被燃烧,使得与燃气轮机中的燃烧气体接触的部件被涂覆(S130)。 在向燃料管线供给的涂料剂停止后,燃气轮机运行固定时间(S140)。 (S110)驱动燃气轮机,以规定的速度和温度开始运转, (S120)向燃气轮机的燃料供给预定的二氧化硅涂布剂; (S130)用二氧化硅涂层剂涂覆一部分燃气轮机; (S140)在预定时间之后停止向燃料管线供应二氧化硅涂层剂,并在预定时间段内操作燃气轮机

    • The rotor blades (11) and hub (10) of the compressor wheel (1) are cleaned by means of a cleaning fluid stream (72) directed along the rotational axis (A) of the compressor wheel onto the compressor wheel. The cleaning fluid stream is run towards or sprayed at the compressor wheel by a supply nozzle (51) arranged on the axis and directed along the axis in the direction of the compressor wheel. The supply stream (72) thus follows the axis and hits the rotational centre of the compressor wheel on the hub of the compressor wheel. The cleaning fluid is thus introduced on the compressor wheel at the rotational centre of the compressor wheel. The cleaning fluid thus runs along the surface of the hub and is carried radially to the radially outer regions by the centrifugal forces.
    • 压缩机叶轮(1)的转子叶片(11)和轮毂(10)通过沿着压缩机叶轮的旋转轴线(A)指向压缩机叶轮的清洁流体流(72)来清洁。 清洁流体流通过布置在轴线上的供应喷嘴(51)朝向压缩机叶轮或喷射在压缩机叶轮上并沿着轴向在压缩机叶轮的方向上引导。 供应流(72)因此遵循轴线并且撞击在压缩机叶轮的轮毂上的压缩机叶轮的旋转中心。 因此,清洁流体在压缩机叶轮的旋转中心处被引入到压缩机叶轮上。 清洁液因此沿着轮毂的表面延伸并且通过离心力径向地径向延伸到径向外部区域。
