At present, the research and development technology of gas boilers is very mature. The boiler has obvious advantages of stable operation and less pollutant discharge and energy saving. However, if the boiler is not used for a long time, it is necessary to maintain the boiler to maintain the normal operation at the subsequent startup.
1. Dry maintenance
The gas-fired boiler needs to be drained after the furnace is shut down, then the internal dirt is completely removed and rinsed, and the drying in the furnace is kept so as not to be eroded.
You can use a small fire when drying the remaining water in the furnace, but you should not use a large fire. Also be careful to close all the hand hole pipe valves and place the quicklime pan in the drum.
If you have not used a gas steam boiler for a long time, check the boiler at least three months. If the quicklime in the crucible is broken into powder, it is necessary to replace the new lime in time to ensure that the dryness protection in the gas steam boiler is not corroded by moisture.
2. Wet maintenance
The specific operation procedure of the wet maintenance is: after the water in the furnace is discharged, the internal dirt is removed, and the treated water is filled into the crucible and then heated to the required temperature; then the gas in the water is completely discharged to the furnace. In addition, close all valves.
However, it should be noted that when the weather is very cold, wet maintenance should not be used to prevent the furnace water from freezing and damaging the furnace and cannot be used.


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.
