摘要： PROBLEM TO BE SOLVED: To provide a gas turbine securing the dust-removing treatment performance of a filter and properly protecting the turbine by preventing a situation in which cooling air containing excessive dust is supplied to the filter. SOLUTION: The gas turbine 1 includes a turbine cooling structure cooling the turbine 4 with cooling air, and the filter 62 performing dust-removing treatment of the cooling air on an upstream side of the turbine 4. The gas turbine 1 includes supply piping 632 supplying the cooling air to the filter 62, branch piping 635 branched from the supply piping 632 upstream of the filter 62, and a means 71, 721, 722 calculating or estimating a flow rate of dust in the cooling air. In the gas turbine 1, when turbine starting, the supply piping 632 is closed and the branch piping 635 is opened. When the flow rate of dust in the cooling air becomes lower than a predetermined threshold value, the supply piping 632 is opened and the branch piping 635 is closed. COPYRIGHT: (C)2011,JPO&INPIT
