Atmospheric hot water boilers and pressurized hot water boilers are two common types of hot water boilers. The main difference lies in the difference between normal pressure and pressure. So, for users who are new to hot water boilers, how to correctly distinguish normal pressure and pressurized hot water boilers and complete the selection? Let Zhengzhou Fangkuai Boiler Factory answer everyone.
1. Look at the pressure change inside the boiler
The biggest difference between these two types of boilers lies in the pressures of atmospheric hot water boilers and pressure boilers. For atmospheric hot water boilers, the pressure of the hot water in the furnace is always the same as the atmospheric pressure, and does not change with the change of water temperature; on the contrary, for pressurized hot water boilers, because the steam-water system in the furnace is composed of a sealed structure; As the water temperature rises, pipes and tubes will naturally change.
2. Look at the water level control of the boiler
In order to realize normal pressure operation, the inlet of the circulating water pump is connected with the outlet of the boiler, and the hot water sucked into the boiler is heated to the user. The user's return pipe and the boiler's water inlet necklace are equal to the water inlet. Atmospheric hot water boiler water level control problem, therefore, the drum and water on the top are still with the open box, water level control problem. However, pressurized hot water boilers do not have water level control problems, which is one of two significant differences.
3. Look at the structural limitations of the boiler
The structural parameters of atmospheric hot water boilers are much simpler than those of pressurized hot water boilers. Different from the strict restrictions on boiler capacity, parameters and installation location in the structure of pressurized boilers, normal pressure hot water boilers only need to arrange the heating surface reasonably to ensure the reliability of water circulation, and there are fewer restrictions on the structure. It can be designed, constructed and installed to a large extent according to the actual needs of users, which is more flexible and convenient.
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.
