Hit Temp heat exchanger

Hit Temp heat exchanger

(OP)
What do you feel a plate and frame or tube style heat exchanger will react with Hastelloy at 1400F?  or Higher.   

RE: Hit Temp heat exchanger

there are several issues to review.

high temperature corrosion is one. Fouling of the surface is another, depending on the working fluid. Fatigue and creep-fatigue effects may also need be considered.

RE: Hit Temp heat exchanger

Plate and Frames have what I call a 300/300 threshold.

That is 300°F and 300 Psig.  BUT not at the same time.

Therefore, your temperature greatly exceeds the capacity of the standard gasketed type P&F.
