Feb 19, 2018 · What is a Subcritical Boiler? Subcritical boilers are boilers that work at temperatures up to 374°C and at a pressure of 3,208 psi (the critical point of water). These boilers compose a system with constant evaporation endpoint. A typical example for a subcritical boiler is the drum-type steam generator.
