Abstract

The invention provides a test device for whole-temperature equal-expansion ratio rotary turbine flowing and cooling and a parameter design method of the test device. The test device is characterized in that the test device comprises a whole-temperature equal-expansion ratio rotary turbine test mainstream system, a cooling air system and a cooling water system, wherein the cooling air system is used for cooling blades of a tested turbine of the whole-temperature equal-expansion ratio rotary turbine test mainstream system, and the cooling water system is used for cooling an air inlet pipeline and an air exhausting pipeline of a tested turbine of the whole-temperature equal-expansion ratio rotary turbine test mainstream system. According to the invention, a pneumatic performance test of a turbine stage mixed with cooling air can be performed and a rotation state cooling effect test of movable blades of the turbine can be also performed.

Description

technical field [0001] The invention relates to a flow and cooling test device and a parameter design method of a full-temperature and equal-expansion-ratio rotary turbine of a heavy-duty gas turbine, belonging to the technical field of gas turbines. Background technique [0002] The turbine inlet temperature of F-class gas turbine reaches 1400°C, the turbine inlet temperature of H-class gas turbine reaches 1500°C, and the turbine inlet temperature of J-class gas turbine reaches 1600°C. The working temperature of the directional crystallization or single crystal nickel-based alloy base metal of the turbine blade is about 900°C to 1000°C, and the temperature drop between the turbine inlet temperature and the working temperature of the turbine blade base metal is 500°C to 600°C. This is achieved by adopting blade cooling structure design and surface thermal barrier coating. The heat insulation temperature of the thermal barrier coating of the turbine blade is about 50°C to 10...
