ABSTRACT:
Heat exchanger apparatus for a gas turbine which is provided with a heat exchanger of the formed plate counterflow type including a core having a gas turbine exhaust gas inlet surface with integral air outlet manifolds, and an inlet gas temperature controller which controls the temperature of the gas impinging on the manifolds and core surface. The temperature controller consists of a housing defining a gas flow path to the heat exchanger core surface, fluid passages within the housing which direct the gas at substantially full gas temperature onto the manifolds, and heat absorber structure within the housing which absorbs heat from the gas to reduce the temperature to less than full gas temperature during transient conditions, such as turbine start-up, and directs the gas onto the core surface.
