What is the critical pressure and subcritical pressure of the boiler?
Mpa (5) times the high pressure boiler 5.3Mpa ≤ P <9.8Mpa (6) medium pressure boiler 3.8Mpa ≤ P <5.3Mpa
1.4.1 Class A Boiler (1) Supercritical Boiler p≥22.1Mpa (2) Subcritical Boiler 16.7Mpa≤P <22.1Mpa (3) 13.7Mpa≤P <16.7Mpa (4) High Pressure Boiler 9.8Mpa≤P <13.7
According to "Boiler Safety Technical Supervision" TSG G0001-2012
Power plant pot search furnace are generally A-class boilers
