First. Reduce the boiler exhaust temperature
1. Increase the heating surface of the tail, that is, install a boiler economizer (or condenser) to reduce the exhaust gas temperature.
2. Arrange the exhaust gas heat recovery device at the tail of the flue to fully absorb the latent heat of the flue gas and improve the operating efficiency of the boiler.
Second. Reduce boiler condensate
The boiler heat loss from the boiler can be fully recovered by increasing the heating surface of the boiler tail or the flue gas waste heat recovery device. Increase boiler load during boiler operation, reduce the number of operating units, and minimize the situation of multiple boilers running at low load. The exhaust temperature of the boiler body is increased as much as possible to avoid the occurrence of condensed water in the boiler body as much as possible, thereby reducing the corrosion of the boiler by the condensed water and prolonging the service life of the boiler.




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:
