Hi, 

 

I just wanted to check that an inlet stream of high pressure steam of 270C and an outlet of 1100C of a reboiler with a duty of 1.5MW is reasonable, ive simulated it and theres no problems, it's just that i dont if the outlet temperature is a bit ridculous

Your reboiler process is not clear to me as described.  More details = better replies.

 

A block sketch of the reboiler with inlet and outlet tube side and inlet and outlet shellside streams specified (T's, P's, flowrates) might help me understand better.

This is not a reboiler! Maybe a boiler?

Whatever it is boiler or reboiler what does it boil if steam was specified at inlet and outlet both?
It is definitely a superheater!

Not enough data; let the guessing continue?  OP help us help you please.

Let guessing goes on

 

Critical temperature of water is 374°C while OP has outlet temperature 1100°C. What means it is a heater - it heats up from 270°C to 374°C, then water becomes supercritical and unable to boil! And tadam - and OP generates steam by heating water, not boiling.
