<p>PROBLEM TO BE SOLVED: To prevent a pipe portion made of Cu, etc. arranged in the vicinity of the inlet of compressed air cooled with a primary heat exchanger from generating erosion. SOLUTION: In this device, the circumference of a pipe 22 portion arranged in the vicinity of the inlet of compressed air cooled with a primary heat exchanger 20 is covered with a tubular member 52 formed of stainless steel, etc. of an anticorrosion member 50. A high temp. of compressed air containing moisture fed at a >=10 m/s high speed to the primary heat exchanger 20 through an introduction port 12 is prevented from being brought into contact with the pipe 22 portion by the tubular member 52 to prevent the pipe 22 portion from generating erosion. At the same time, even though the high temp. of compressed air containing moisture fed at the >=10 m/s high speed to the primary heat exchanger 20 through the introduction port 12 is brought into contact with the tubular member 52 covering the circumference of the pipe 22 portion, the tubular member 52 is made so as not to generate erosion.</p> |
