Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Detailed description of the invention: gas turbine 1, compressor 11, combustion chamber 12, turbine 13, load 14, starter 2, air blower
21, heater 22, the first valve 23, the second valve 24, motor 25.
Specific embodiment
Technical solution of the present invention is described further below in conjunction with attached drawing.
A kind of starting method of gas turbine of the invention, 21 outlet air of air blower form working medium, the work by heater 22
Matter has the characteristic of high temperature and pressure, is blown on the impeller of compressor 11, is preferably blown at 11 blade tip of compressor using working medium.It calms the anger
11 outlet side of machine is again introduced into air blower 21, to form circulation, until the compressor 11 of gas turbine meets self-operating requirement,
The starting for completing gas turbine, can close air blower 21 and heater 22.
In method of the invention, the first valve 23 can be added between 11 outlet side of compressor and air blower 21；Adding
The second valve 24 is added between hot device 22 and compressor 11.So on startup, valve is opened, after completing starting, closes valve.
Effect can be made to start more preferably by the control of working medium circulating direction and pipeline safety is higher.
A further embodiment of the present invention the most, air blower 21 can also use ventilation blower.
