<p><P>PROBLEM TO BE SOLVED: To provide an exhaust heat recovery boiler capable of being stably used 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 becomes approximately 50 m/s and 100 m/s depending on circumstances. <P>SOLUTION: When generating steam in heat exchanger tubes by making the exhaust gas from the gas turbine flow into the exhaust heat recovery boiler in which the panel harps 13 formed by binding a plurality of the heat exchanger tubes are hung down, a plurality of honeycomb supports 29 having prescribed widths for binding the panel harps 13 in a horizontal direction perpendicular to a flow direction of the exhaust gas and a plurality of horizontal supports 19 are arranged at a plurality of stages in up-and-down directions, and a plurality of heat transfer tube portions at both sides of the respective panel harps 13 as the honeycomb supports 29 and the horizontal supports 19 can prevent the vibration of the panel harps 13 by making widths of the honeycomb supports 29 and the horizontal supports 19 wider than prescribed widths even if the swirl flow of the exhaust gas of the high-temperature/high flow-speed gas turbine is generated. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
