Refer to auxiliary machine configuration, the water treatment will be placed in the first place. What is the meaning of water treatment?
Simply speaking, boiler water treatment refers to pre-softening the water flowing into the boiler and then flowing into the boiler for related use.
Natural water contains various salts. These salts are dissolved in cations and anions, mainly composed of calcium and magnesium ions, and are collectively referred to as "hard water". The minerals contained in these hard water boiled in the container and gradually form a white block or powdery solid, which is called "scale".
There are three major hazards in scale.
1. Due to the extremely poor thermal conductivity of scale, heat absorption is reduced during heating, boiler thermal efficiency is reduced, fuel utilization is reduced, and boiler operating costs are increased.
2. Fouling will cause the temperature of the furnace wall to increase exponentially. The stress of the steel is destroyed and the strength is reduced. In severe cases, the bursting phenomenon will occur, which will seriously reduce the service life of the boiler.
3. The calcium and magnesium ions in the water will be integrated into the water during the heating process, which will directly affect the steam quality. At the same time, if the boiler parts such as safety valves, pressure gauges and pressure controllers are scaled, it will cause blockage.
Water treatment method.
Boiler water treatment usually uses a combination of a resin tank and a salt tank. When the raw water containing calcium and magnesium ions passes through the resin layer of the exchanger, calcium ions and magnesium ions in the water are adsorbed by the resin while releasing sodium ions. The water that flows out of the exchanger is the demineralized water from which the hardness ions are removed. When the resin adsorbs a certain amount of calcium and magnesium ions, it must be regenerated. In the regeneration process, the resin layer is washed with a high-concentration sodium oxide solution in the salt can, and the hardness ions on the resin are replaced, and the resin is restored to the softening exchange function as the recycled waste liquid is discharged out of the tank.
On-site practice:
1. Check the inlet water pressure (0.2-0.4MPa); check whether the high-concentration brine in the pipe is sufficient; check whether the salt pipe and the sewage pipe are blocked; if there is any abnormality, start it after cleaning.
2. Close the tap water bypass valve.
3. Open the salt water inlet pipe valve and open the outlet pipe valve; open the demineralized water to the soft water tank manual and electric valve.
4. The control valve is energized and the cycle water quantity parameter is set.
5. start running.
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.
