<p><P>PROBLEM TO BE SOLVED: To provide an exhaust heat recovery boiler which can stably use an HRSG while suppressing the vibration of panel harps which are excited by a swirl flow of an exhaust gas of a high-temperature/high flow-speed gas turbine whose temperature is approximately 650°C and whose speed is not lower than approximately 50 m/s. <P>SOLUTION: The exhaust heat recovery boiler is constituted in such a manner that, when, for example, the exhaust gas 11 of the high-temperature/high flow-speed gas turbine whose temperature is approximately 650°C and whose speed is about 50 to 100 m/s forms the swirl flow in the exhaust heat recovery boiler, and when the panel harps 13AL to 13CR are about to excite vibration, second connecting members 52A, 52B and 52C, or 53A, 53B for connecting the adjacent two panel harps out of the panel harps 13AL to 13CR which are arranged in a direction orthogonal to a flow of the exhaust gas are made to be changeable in a displacement freedom by one pin 26 or two pins 25, 25 according to the relative displacement of the adjacent two panel harps 13AL to 13CR. By this arrangement, stabilized vibration modes of all the panel harps 13AL to 13CR can be formed, and a sufficient vibration energy absorption effect can be obtained. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
