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.
Recently, Zhengzhou Fangkuai Boiler Sales Co., Ltd. traveled to Dhaka, the capital of Bangladesh, to attend the Bangladesh International Textile, Knitwear & Garment Industry Exhibition (BTKG 2026). It showcased industrial thermal equipment and system solutions adapted to the whole process of textile printing and dyeing, actively expanding the South Asian market.
Bangladesh is an important global producer and exporter of textiles and garments. As a pillar local industry, the textile sector has long-term and strong demand for high-efficiency, stable and energy-saving industrial boilers and thermal equipment, with broad market potential. This exhibition participation is an important measure for Zhengzhou Fangkuai Boiler Sales Co., Ltd. to advance its internationalization strategy and further explore overseas markets.

Relying on its technological accumulation and manufacturing advantages in the field of thermal energy equipment, the company provides targeted thermal energy solutions for local textile, printing and dyeing, garment manufacturing and other industries, helping enterprises improve production efficiency and reduce operating costs. In the future, Zhengzhou Fangkuai Boiler Sales Co., Ltd. will continue to focus on overseas market demands, continuously optimize its product and service system, facilitate the high-quality development of the global textile industry with professional and reliable products, and steadily enhance the brand’s competitiveness and influence in overseas markets.

Trust stems from quality
At the beginning of the new year, Fangkuai Boiler and a leading domestic new energy company have reached another important cooperation, successfully signing an order for a total of 500 steam tons.
