In my case , I need to heat stream from 560 to 610 C by using steam at 730 C . Is it possible to use shell and tube heat exchanges ?
Shell and Tube could be use as long has you developed a design that will meet the safety requirement for using super heat steam. I can imagine this design to be like a boiler to produce low pressure super heated steam to 730'C with a shell and tube used has a desuper-heater. If this is a R&D project, steam could be acceptable since your energy and equipment cost would be very high for a close loop system. On the other hand, if your boiler is an open loop, the equipment cost would be lower but you may want to use de-mineralize water. If you would like to be more energy efficient while reducing the cost of the equipment, you may want to consider something else instead of steam for your heat source for the hot side of the shell and tube. Maybe using N.G. flue gases or something more unusual.
Hi Parvin,
Basically, temperature of the shell and tube heat exchanger depends upon different factors. But, most important factor is the materials by which the heat exchanger was made and the type of fluid which flows through the heat exchanger. I think, it will be helpful for you.
Hi
Yes it can goes up, and personally, I had experience in a case that shell inlet T was 1000 C.
Most important factor is how to solve the expansion of tubes in tube bundles
Agree with previous suggestions.
Add that it is possible. In 2013 we worked with a 850 °C flue gas inlet stream in a test facility.
Basically it's a matter of materials
Have a look to this (a little bit dated...) paper, and good luck!

I agree that it is possible to use a shell and tube exchanger but it is probably more appropriate to use a fired heater with radiant and convection section services.
Yes , Dear Rick . In this project , there was a design mistake . Instead of fired heater , shell and tube heat exchanges was used . When I realize it , it was very late and I should deal with high temperature shell and tube heat chargers . This was a bachelor degree final year project and I have finished it already .
Thanks to all of reserachgate members who had made a contribution or tried to make a contribution . Thanks you all for sharing knowledge .
