HEAT EXCHANGER AND GAS TURBINE PLANT PROVIDED THEREWITH

摘要

The heat exchanger is provided with a body, multiple heat transfer tubes (20) which are arranged inside of the body, and multiple support plates (30) which are arranged at intervals along the longitudinal direction of the heat transfer tubes (20) and in which multiple tube insertion through-holes (40) for inserting the multiple heat transfer tubes (20) are formed. In two of the support plates (30) adjacent in the aforementioned longitudinal direction, the shapes of the tube insertion through-holes (40) for the same heat transfer tube (20) are different.
