Compared with pressurized hot water boilers, atmospheric hot water boilers have the advantage of safety and low explosion risk. This is because the top of the atmospheric boiler is directly connected to the atmosphere and does not withstand the static pressure of the water column of the heating system. It can also be understood as an "open hot water tank".
But this is not to say that there is no special attention when the atmospheric hot water boiler is running. On the contrary, the boiler should pay attention to many details when it is running.
1. The system water
The heating system should be equipped with a high-level bearing box, which is located at the high point of the system. The rainwater system is connected to the return pipe and is filled into the system through the tap water pressure. At the same time, the system discharge is normal, so that the system can replenish water. After the high water tank overflows, the water pump cycle is started. Replenish water until the system is full.
2. Check the activation valve before running
Firstly, the valve of the boiler inlet and outlet is opened, and the circulating water pump is turned on to make the system circulate and flow to check whether the automatic opening and closing valve is sensitive. Then the circulating water pump stops running for 1-2 hours, paying attention to the water level of the boiler.
If the water level changes little here, the automatic opening and closing valve of the table name is closed tightly. If the boiler water level rises rapidly after stopping the pump, it indicates that the automatic opening and closing valve leaks seriously and needs to be repaired or replaced in time.
When the automatic opening and closing valve fails or the leakage is serious, it cannot be ignited.
3. Stop the furnace
When the atmospheric hot water boiler is shut down, the operation of the combustion equipment is the same as that of the pressurized boiler, but it is not limited by the requirement that the boiler water temperature is below 50 °C. If a serious water hammer is caused by vaporization during the shutdown, the boiler can be used to replenish water, and the overflow pipe can be used to reduce the furnace temperature and weaken the vaporization phenomenon.
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.
