Hot topics: just what is supercritical steam? - CSIROscope

We know that regular steam is powerful enough to run train engines, and we've seen its pressure lift the lid on a boiling saucepan. But steam is considered to be supercritical once its pressure and temperature pushes it past the critical point into a phase where water and vapour coexist (if your saucepan was able to create supercritical steam it would never boil but just keeping getting

Raising the pressure: supercritical boilers

Dear Control Engineering: Looking at the article about new ultra-supercritical power plants, I have to ask what supercritical means, and why it matters.. If you think of what water looks like in a boiling pot, steam forms in bubbles in the water and rise to the surface. If the pressure in the boiler is higher than 3,200 psi, bubbles cannot form in the water, so the water converts directly to
