Key Difference - Subcritical vs Supercritical Boiler What

Supercritical boiler (supercritical steam generator) is a type of boiler that works under supercritical pressure conditions. This type of boilers is often used in generating electricity. Unlike in subcritical boilers, there is no bubble formation in supercritical boilers, and liquid water immediately converts into steam.
