Different steam pressures correspond to different steam temperatures.
The steam temperature of low-pressure boiler is mostly saturation temperature or not higher than 400℃.
The outlet pressure of medium-pressure boiler is 3.8 ~ 5.4 MPa, and the common steam temperature is 450℃.
The outlet pressure of sub-high pressure boiler is 5.4 ~ 9.8 MPa, and the common steam temperature is 540℃.
The outlet pressure of high-pressure boiler is 9.8～13.7MPa, and the common steam temperature is 540℃.
The outlet pressure of ultra-high pressure boiler is 13.7 ~ 16.7 MPa, and the outlet steam temperature is mostly 540℃, in some cases is 555℃.
The outlet pressure of subcritical pressure boiler is 16.7 ~ 22.1 MPa, and the common steam temperature is 538℃.
The outlet pressure of supercritical pressure boiler is 22.1 ~ 27.0 MPa, and the common steam temperature is 538 ~ 543℃ or 538 ~ 566℃.
The ultra-supercritical pressure boiler pressure is ≧27.0 MPa, and the rated outlet steam temperature is ≧590℃.

In industries such as chemicals, plastic packaging, new materials, and building materials, thermal energy supply is closely related not only to production continuity, but also to product quality and operating costs. As companies place higher requirements on process temperature control, fuel adaptability, and system stability, thermal oil boilers are becoming an important heat source in many industrial applications. Based on different fuel conditions and production needs, ZOZEN Boiler continues t...02 Jun 2026 -
Packaging connects production with consumption. A carton, a piece of corrugated board, or a roll of plastic film may look light and simple, but behind each of them is a stable, continuous, and process-matched thermal energy system. As demand continues to grow in food packaging, industrial packaging, e-commerce packaging, and plastic packaging, the packaging industry is placing more specific requirements on boiler equipment: stable steam supply, fuel adaptability, process temperature control, ope...26 May 2026 -
When an industrial boiler arrives on site, what first catches a customer’s attention is often not the specification sheet, but the overall appearance of the equipment in the plant environment. For boiler equipment, exterior design is not only about visual presentation; it also reflects the manufacturer’s approach to product details, on-site management, and brand image. ZOZEN Boiler has upgraded the exterior of its SZL series biomass boiler, presenting a more unified visual design and...19 May 2026
