Steam boilers are medium-sized equipment among special equipment and are often used in industrial production. Gas-fired steam boilers have many advantages such as high operating efficiency, low pollutant emissions, and long service life. Therefore, they are also very popular in the user market, and their use frequency is increasing year by year. Many users are more interested in the price of a single gas-fired steam boiler. Zhengzhou Fangkuai Boiler Factory takes 6 tons of gas-fired steam boiler equipment as an example to explain to everyone.
At present, the operating efficiency of a single 6-ton gas-fired steam boiler on the market is generally around 70%, which is a relatively medium figure. The gas-fired steam boiler launched by Zhengzhou Fangkuai Boiler Factory adopts a new type of condensing recovery technology, and its operating efficiency can reach more than 98%; combined with low-nitrogen combustion technologies such as full premixing and FGR, the nitrogen oxide emissions of the boiler can be reduced to Below 30 mg/cubic meter, once it was introduced into the market, it was praised by numerous users. At present, the price of a single unit of this type of boiler ranges from US$40,000 to US$40,000, depending on the boiler model and the configuration of auxiliary equipment.
Zhengzhou Fangkuai Boiler Factory is here to remind everyone that in the boiler equipment, the expansion indicator is a relatively important equipment, mainly used to monitor the expansion of thick-walled pressure vessels such as steam drums and headers during the ignition and pressure rise process. Yes, it can be used to detect the deformation of the evaporation equipment caused by improper ignition boost or poor installation and maintenance, and prevent cracks and leaks from uneven expansion. Generally installed on the header and steam drum.
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:
