Most steam boilers have a certain pressure to output high-temperature steam while heating water. They are special pressure equipment specified in China and implement special operating specifications. Whether the operation meets the requirements will directly affect the life of the boiler, which is why some steam boilers have a short service life, but some can achieve an extremely long service life.
When the wrong operation causes the steam boiler to leak, don't panic, we can save it.
First, the cause
1. The boiler feed water does not have oxygen removal. The high oxygen content in the water causes the oxygen to escape and accumulate in the gas space during the boiler operation.
2. Improper daily operation, when the furnace is shut down, the water supply valve or the main pipeline steam valve is not closed in time, causing the air to enter the furnace, so that when the pressure is increased again, the invading oxygen is not removed in time, so that the oxygen is caused in a hot and humid environment. Long-term corrosion perforation of the pipe.
Second, the standard operation
1. Boiler feed water is deoxidized according to GB1576-2008 standard to reduce oxygen content.
2. When the furnace is shut down, stop the boiler when the boiler is at normal high water level and normal pressure, then close the inlet valve and the main air valve to prevent outside air from invading the furnace.
3. When starting the furnace, first open the main air valve for exhausting. When the pressure reaches 0.1-0.15MPa, close the main air valve to remove the air in the furnace, and then open the main air valve to supply air when the rated working pressure is reached.
4. Strengthen valve maintenance and maintain rigor.
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.
