Vacuum hot water boiler is a kind of boiler equipment that forms a negative pressure vacuum environment in a closed boiler body to quickly boil water and heat high temperature water for heating and heating. It is mostly used in hotels, residential quarters, office buildings, Shopping malls and other heating, sanitary hot water heating fields. The pressure in the boiler body is always under vacuum when working, so the heat exchange rate and utilization rate are high, and it has also been recognized and trusted by many users. However, Zhengzhou Fangkuai Boiler Factory suggests that in order to better protect the boiler body and ensure the safe use of the boiler, the following issues should be paid attention to during the operation of the vacuum hot water boiler:
1. Before each operation of the vacuum hot water boiler, the gas pressure of the boiler must be checked to ensure that its pressure is normal. If the static pressure is only 6 kPa, it should be noted that only a small fire can be maintained, because at a pressure of 6 kPa, the boiler running on a large fire may cause flameout due to insufficient pressure.
2. When using a vacuum hot water boiler, pay attention to the pressure and temperature of the domestic hot water and heating medium water, and make sure that the pipeline valve is opened to prevent the inlet and outlet water valves of any heat transfer branch from closing, because during use, due to thermal expansion And the principle of cold shrinkage, the pressure will far exceed the rated working range. This caused major accidents such as pipeline explosions and boiler scrap.
3. Under various normal working conditions of the vacuum hot water boiler, pay attention to the operation of the water pump, carefully observe the outlet pressure of the water pump and its sound, and turn on the boiler control power supply when it works normally.
4. When the vacuum hot water boiler is in operation, pay attention to setting the relevant parameters on the display screen to ensure that the middle water temperature, the outlet water control temperature, the flame conversion temperature and the temperature difference can meet the operating requirements.
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.
