Claims

[Scope of utility model registration request]

The high-temperature, high-speed gas fluid that flows into the inner shell from the gas inlet nozzle at the bottom of the outer shell passes through the gaps between the heat transfer tubes between the notches provided at regular intervals, changes direction, and rises to cool the inside of the heat transfer tubes. In a heat exchanger for high temperature fluid that exchanges heat with water, a perforated plate having a large number of pores is installed between the gas inlet nozzle and the heat exchanger tube group, or at the inlet and outlet of the heat exchanger tube group so as to sandwich the heat exchanger tube group. A heat exchanger for high-temperature fluid, characterized in that a buffer plate is provided in parallel with the heat transfer tube so that the entire amount of incoming gas passes through it.
