Different types of boiler pressures are also different. According to the pressure, there are mainly low-pressure boilers, medium-pressure boilers, high-pressure boilers, ultra-high pressure boilers, subcritical boilers, critical boilers, supercritical boilers and ultra-supercritical boilers. The following are specific The pressure divides.
1. Low pressure boiler
The outlet steam pressure is ≤2.45MPa, and the steam temperature is mostly saturated temperature or ≤400°C.
2. Medium pressure boiler
The outlet steam pressure is in the range of 2.94-4.90 MPa. According to the current series of power plant boilers, the steam pressure at the outlet of the medium pressure boiler is 3.83 MPa and the steam temperature is 450 °C.
3. High pressure boiler
The outlet steam pressure is 7.84-10.8 MPa. According to the current series of power plant boilers in China, the outlet steam pressure of the high-pressure boiler is 9.81 MPa, and the outlet steam temperature is 540 °C.
4. Ultra high pressure boiler
The outlet steam pressure is 11.8-14.7 MPa. According to the current series of power plant boilers in China, the steam pressure at the outlet of the ultra-high pressure boiler is specified as 13.7 MPa, the steam outlet temperature is 540 ° C, and the minority is at 555 ° C.
5. Subcritical pressure boiler
The boiler with an outlet steam pressure of 15.7-19.6 MPa. According to the current series of power plant boilers in China, the subcritical pressure boiler outlet steam pressure is specified as 16.7 MPa, the outlet steam temperature is 540 ° C or 555 ° C, and a few are 570 ° C.
6. Supercritical pressure boiler
For boilers whose outlet steam pressure exceeds the critical pressure, the critical pressure of water vapor is 22.1 MPa. At present, the supercritical pressure of power station boilers is mostly between 25-27 MPa.
We, Zhengzhou Fangkuai Boiler Co., Ltd. (Fangkuai), are excited to announce our participation in the Indonesia International Heating Technology Exhibition 2025. We will be showcasing our advanced boiler systems engineered for higher efficiency, lower emissions, and sustainable energy performance. Join us at Booth No. B1-08 from November 5–7, 2025 at the Jakarta Convention Center.
The event brings together EXPO BOILER, EXPO BIOMASS, EXPO PUMPS & VALVES, and EXPO CRANE — creating a comprehensive platform for technology exchange and business collaboration across the industrial heating and energy sectors in Southeast Asia.
At the exhibition, we will present our integrated solutions including biomass boilers, industrial steam systems, and full power plant EPC services. Our products emphasize:
