1. The most common problem is that boiler water treatment is not implemented. At present, some boilers are often not taken seriously because they are relatively small in capacity, or are used only in winter, and those who manage small boilers often have insufficient experience in boiler water treatment, and no boilers are implemented in the boiler management process. Effective boiler water treatment causes scaling or corrosion of the boiler, which has a serious impact on boiler management over time.
2. The boiler water treatment method is improper. At present, many enterprises have often adopted unscientific methods for the treatment of boiler water in order to save more expenses, and the tools and instruments used in the process of boiler water treatment do not comply with the relevant regulations. This kind of practice can not fundamentally solve the problem of boiler scaling and corrosion, and at the same time not only causes waste of energy but also reduces the service life of the boiler. Moreover, if the anti-scaling agent is used improperly, it will have the opposite effect on the protection of the boiler, accelerate the scaling and corrosion of the boiler, and bring serious threat to the normal operation of the boiler.
3. At the same time, there are still problems with boiler water treatment equipment. If the water quality of the water treatment equipment used in the boiler water treatment is not good, and the water discharge efficiency is not high, the boiler scale and corrosion are often accelerated. The main reason is that the resin is damaged and eventually oxidized; or the inner wall of the iron boiler is not treated promptly and properly, resulting in iron poisoning of the resin.
4. In addition, many companies do not pay attention to the pH of boiler water. For steam-type boilers, the water hardness index is very important. The hardness of the boiler water often affects the later scaling and corrosion problems. If the hardness of the boiler water is high, the boiler water will be fouled by evaporation, and the hot water boiler is relatively more susceptible to corrosion.
All of the above are some problems in water treatment at this stage. You can check your own gas boiler first to see if there are any problems. Early detection and early settlement will enable the boiler to create more benefits for you.
We, Zhengzhou Fangkuai Boiler Co., Ltd. (Fangkuai), are excited to announce our participation in the Indonesia International Heating Technology Exhibition 2025. We will be showcasing our advanced boiler systems engineered for higher efficiency, lower emissions, and sustainable energy performance. Join us at Booth No. B1-08 from November 5–7, 2025 at the Jakarta Convention Center.
The event brings together EXPO BOILER, EXPO BIOMASS, EXPO PUMPS & VALVES, and EXPO CRANE — creating a comprehensive platform for technology exchange and business collaboration across the industrial heating and energy sectors in Southeast Asia.
At the exhibition, we will present our integrated solutions including biomass boilers, industrial steam systems, and full power plant EPC services. Our products emphasize:
