Supercritical steam generator - Wikipedia

2019-10-20 · A supercritical steam generator is a type of boiler that operates at supercritical pressure, frequently used in the production of electric power.. In contrast to a subcritical boiler in which bubbles can form, a supercritical steam generator operates at pressures above the critical pressure – 3,200 psi or 22 MPa.Therefore, liquid water immediately becomes steam.

Boiler Pressure - an overview | ScienceDirect Topics

Boiler pressure is the key factor for determining the requirement of a CPU system (see Figure II/3.6.6-1). For the steam generator plant with low steam pressure (below 40 kg/cm 2), the requirement of a condensate polishing unit is usually avoided. Hard scale formation and boiler metal corrosion can easily be prevented through feedwater
