Atmospheric boilers and pressure-bearing boilers, as the name implies, atmospheric boilers refer to boiler equipment with a normal pressure inside, while pressure-bearing boilers are boiler equipment with a certain pressure inside. According to different pressures, they are divided into overpressure. , High-pressure, medium-pressure, and low-pressure boilers, the applicable industry groups are also different.
For users who are new to boilers, how to quickly distinguish whether it is an atmospheric boiler or a pressure boiler through the boiler nameplate? Let Zhengzhou Fangkuai Boiler Factory tell you the answer.
First of all, we need to know all the parameters on the boiler nameplate. If the boiler nameplate has a rated steam pressure, even if it is 0.1MPA, it is a pressure-bearing boiler. Generally speaking, steam boilers are pressure boilers, and most of hot water boilers are atmospheric pressure boilers.
The steam boiler nameplate is generally marked with the model number. Take the WNS2-1.25-Q boiler as an example. WNS refers to the classification of the boiler, that is, the horizontal internal combustion chamber fired boiler. 2 refers to the rated steam volume of two tons, 1.25 It means that the rated steam pressure is 1.25Mpa, which is generally referred to as a pressure of 13 kg. The following Q refers to the type of boiler fuel, and Q refers to the gas furnace.
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:
