Heating steam, not water, with microwave energy

Click For Summary
SUMMARY

The discussion centers on the feasibility of superheating steam using microwave energy, specifically at pressures of 300 psi (417 degrees F) and returning steam at 100 psi (328 degrees F). Participants highlight the inefficiencies of using electrical energy for heating steam, suggesting that direct use of electricity in an electric motor is more efficient than employing a turbine. The consensus indicates that while immersion and resistance heating are superior for water, the practicality and efficiency of superheating steam with microwaves remain questionable.

I see a lot of information posted on the inefficiencies of heating water to steam with microwave energy. I was wondering if anybody has thoughts on super heating steam with microwave energy? For example, could you run steam through a turbine at 300 psi (417 degrees F), return steam at 100 psi (328 degrees F), still in vapor form, and then super heat it back up to 300 psi (417 degrees F). If so, what kind of efficiency are we looking at? I agree that immersion/resistance heating is the most efficient means to heat water, but what about heating steam vapor?

Hi and welcome to PF.
I have to ask you why you would want to do this. Using electrical energy as a source for a heat engine is very bad value as the original electricity is already available to do all the work that your turbine might do - and without thermodynamic efficiency limits. An electric motor would replace your turbine and cut out the middle man. ;)
