摘要： Contrarotating outward-flow gas turbine without stators and with two rotors (1 and 2) which set in motion the power shaft (3) and the compressor shaft (17), respectively. The inlet air (19) is sent through the impellers (20) of the outward-flow compressor to the manifold (22) and from there to the regenerator (24) where it is preheated; then, it reaches the combustion chamber (14) and from there it expands to the rotors, and finally passes through the exhaust manifold (27). The rotors (1 and 2) contrarotate coaxially on their bearings (11), both rotors having one or a plurality of rings of vanes (5, 6, 7, 8), and additionally flow guiding fins (9).

摘要： Providing a turbine wheel that includes, but not limited to: a plurality of blade parts and a scallop cut-out profile, the scallop cut-out profile being formed by cutting-out the back side wall part of the turbine wheel between the suction surface side of a blade part and the pressure surface side of the adjacent blade part, wherein the leakage flow on the rear side of the blade part is constrained so as to enhance the turbocharger efficiency. Providing the blade part 5 (i.e. the area between the scallop parts on the tip end side of the blade part) with the suction surface side extended part 25 in the neighborhood of the suction surface 21 of the blade part so that the thickness of the blade part on the tip end side of the scallop cut-out profile is increased; or, the pressure surface side extended part 32 in the neighborhood of the pressure surface 19 of the blade part so that the thickness of the blade part on the tip end side of the scallop cut-out profile is increased. Or, the positive/suction surface side extended parts are provided. Thereby, the extended width of the extended part is formed so that the width is an almost constant width along the camber line of the blade part from the tip end side to the root side of the blade, the projecting-out width part forming a strip area.

摘要： An object of the present invention is to provide a turbine protection device which can interrupt steam flowing backward from a deaerator (5) to a turbine (2) completely even if a check valve (3a) provided between the deaerator (5) and the turbine (2) can not interrupt the steam flowing between the deaerator (5) and the turbine (2) completely. In order to achieve the above object, a control unit (11) sends commands to a shutdown valve device (12) so as to close the shutdown valve device (12) when a differential pressure resulted from subtracting a pressure of a extraction steam from a pressure within the deaerator (5) becomes equal to or greater than a first predetermined value. As a result, the steam flowing backward from the deaerator (5) to the turbine (2) is interrupted by a stop valve of the shutdown valve device (12).
摘要翻译：本发明的目的在于提供一种涡轮保护装置，即使在脱气器（5）与涡轮（2）之间设置止回阀（3a），也能够完全阻止从脱气器（5）向涡轮（2）（2）不能完全中断在除氧器（5）和涡轮机（2）之间流动的蒸汽。为了实现上述目的，控制单元（11）向关闭阀装置（12）发送指令，以便当通过从第一控制单元（11）减去抽取蒸汽的压力而产生差压时关闭关闭阀装置（12）脱气器（5）内的压力成为第一规定值以上。其结果是，从除气器（5）向涡轮（2）后退的蒸汽被截断阀装置（12）的截止阀截断。
