When purchasing gas boilers, boiler operating efficiency and service life are important reference indicators. However, to achieve the boiler operating efficiency and service life double standards, not only to choose a good quality gas boiler is so simple, it is also very important to carry out regular maintenance work in the later stage of boiler operation.
This is mainly due to differences in gas quality and water quality in different regions and different enterprises.
1. Gas quality difference
Natural gas and liquefied petroleum gas are relatively pure gas sources. Artificial gas is relatively poor. It has many internal impurities, and its composition is not stable. The calorific value is low, which has a great impact on equipment operation and life.
2. Water quality differences
China has a large land area, and there are large differences in water quality. The content of calcium and magnesium ions in water is different. Although the water used in boilers is treated softened water, it is not easy to scale, but softening only reduces the content of calcium and magnesium ions in tap water. And can not be completely eliminated. When water is heated, calcium, magnesium, iron ions, etc. in the water are rapidly combined with carbonate, silicate, hydroxide ions, etc. in the water to cause scales such as calcium carbonate and magnesium silicate, and are firmly attached thereto. The inner wall of the heat exchanger and the pipeline causes the heat exchange effect of the system to be deteriorated, the pipe diameter is reduced, the water flow is not smooth or blocked, and the energy consumption is increased, and the boiler water pump is clogged and the water flow is not smooth, and the fault is easy to occur. The heat exchanger is also easily damaged at high temperatures of the flame, thereby shortening the service life of the boiler water circulation system equipment.
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:
