Boiler Introduction | CleanBoiler.org

A steam turbine converts energy from internal energy, in the form of heat, into mechanical energy, that is, energy that can be transformed. The laws of thermodynamics state that when a vapor expands, its temperature drops, and its internal energy is consequentially decreased.

Steam—chapter_superheat

Steam pressures and temperatures in current practice have reached 97–164 bar and 480–565°C or 593°C. The rate of increase in efficiency with increase in pressure becomes less as the pressure increases. A limit to the practicable operating pressure is set by the difficulty in separating moisture from steam in the boiler drum.

Boiler Ratings - Spirax Sarco | First for Steam Solutions

To generate steam, you have to reach at least 100C, or 212 degrees Fahrenheit. However, the more pressure that exists in the boiler, the higher the temperature can be. So you could have a boiler with a water temp of 450 degrees F. Someone who knows more about steam than I do can tell you what pressure it would be at in this condition.
