No matter what equipment it is, it has a service life, and the same is true for steam boiler equipment. However, through correct maintenance and maintenance, the service life of the boiler can be effectively extended, thereby improving the cost-effectiveness of the boiler. So, how many years is the general service life of a steam boiler? Let Zhengzhou Fangkuai Boiler Factory tell you the answer.
The service life of a general steam boiler is 20-30 years. According to the quality of the boiler and the use and maintenance of the boiler, the service life of some high-tech steam boilers can reach more than 30 years. But it does not mean that the steam boiler must be scrapped for how many years it has been used, but according to the annual inspection, once the annual inspection fails, it can continue to be used after the annual inspection after the overhaul. If the overhaul still fails to meet the monitoring standards, the steam boiler will have to face Mandatory scrapping.
For steam boilers, the so-called “return” in the boiler industry means: the flame of the burner starts from the burner end inside the boiler and travels several times back and forth inside the boiler. The three-return journey means that the flame goes back and forth three times in your burner. The three-pass steam boiler, if it is a three-pass center flame return, is more environmentally friendly than other boilers because of the presence of secondary combustion. This is also the mainstream furnace structure in Germany and China.
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:
