From the names of atmospheric hot water boilers and non-pressure hot water boilers, we can distinguish that the former does not carry pressure and the latter carries pressure. This is a simple and intuitive difference. But in fact, there are many differences between the two types of boilers, and the applicable industry fields and operating locations are also different. Everyone should choose the appropriate boiler model according to their own needs for the hot water boiler, so that the boiler can work better for us. Xie Gong from Zhengzhou Fangkuai Boiler Factory introduced these two types of boilers to help everyone understand them more comprehensively.
In my country, atmospheric hot water boiler is also called pressureless hot water boiler, which means that the top of the boiler usually does not bear the static pressure of the water column of the heating system, which is equivalent to an "open hot water tank".
The meaning of atmospheric hot water boiler is that the opening of the boiler body communicates with the atmosphere. Under any working conditions, the boiler whose gauge pressure is zero at the boiler water level line; the boiler product model of atmospheric boiler is composed of three parts, and each part is connected by a short horizontal line.
Pressurized hot water boilers are the closed boilers we usually see. The steam and water system in the boiler is composed of closed containers and pipes, heated by flames, and subjected to fluid pressure during work, and belongs to special equipment.
The standard steam of the boiler refers to controlling the pressure and flow rate of the boiler in strict accordance with the process indicators. Steam includes saturated steam and superheated steam, which are divided into low pressure, medium pressure and high pressure steam.
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.
