For the normal operation of industrial boilers, a large amount of continuous water is indispensable. This water may be groundwater, river water, etc. If it flows directly into the boiler without pre-treatment, it will definitely cause considerable damage to the boiler in the long run. Zhengzhou Fangkuai Boiler Factory invites you to soften the boiler inlet water.
When softening the water, a water softening device should be used together. A portion of salt can be added. The concentration of the brine is generally 8% to 10%, or it can be saturated at all, depending on the usage of the boiler.
Although the boiler inlet water has been softened, it is inevitable that some dirt will be generated. At this time, the blowdown operation is required. Zhengzhou Fangkuai Boiler Plant has compiled the following procedures for the blowdown of industrial boilers for your study and reference.
1. Eliminate the excess salt and alkali in the boiler water, so that the boiler water quality indicators are always controlled within the scope of national standards.
Only by ensuring good boiler water quality and slowing down or preventing scale formation can the safe operation of industrial boilers be ensured.
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:
