As a leader in the field of clean and environmentally friendly boiler equipment, Fangkuai Boiler has invested a lot of time and energy for many years to actively carry out research and development and testing, only to provide users and friends with better quality, higher operating efficiency and longer service life. Longer, more cost-effective boiler equipment. In 2021, what advantages does Fangkuai Boiler's new gas-fired steam boiler have that ordinary gas-fired boilers do not have?
1. Start-up operation of gas-fired steam boiler: minimalist operation, extremely fast startup
The boiler adopts wing tube + threaded tube, the heat flow density on the flue gas side is increased; the heat exchange element is small and the heat absorption capacity is strong; the radiant heating element is connected with a linear expansion ring, and the elongation of the furnace bladder caused by heating is absorbed by the expansion ring. The additional stress on surrounding components is small; the eccentric arrangement is beneficial to the natural circulation of water in the boiler, the boiler water quickly reaches temperature balance, the boiler shell temperature is uniform, and the temperature difference stress is small. In the end, the boiler water volume is reduced to below 45% of conventional products to meet the industry demand for fast heat engines.
2. The operating state of gas-fired steam boiler is more balanced.
The steam condensed return water produced by the boiler is consistent with the boiler water cycle to maintain the dynamic balance of the medium load; the boiler also has a larger steam space design to alleviate the risk of low water level caused by a large amount of backwater inrush instantaneously or a long time delay. The method of circulating the water tank and the air heater transfers energy to the combustion air. Make the water tank have heat capacity.
3. The utilization effect of gas-fired steam boiler is more full.
Shutdown: After the furnace is shut down, the maximum capacity of the system to reflux condensate is saved for use in the next production cycle.
Steam condensate is slowly reduced in pressure and returned, adjusted by a pneumatic valve, so that the condensed return water is supplied to the appropriate height of the furnace body, ready for the next operating cycle; when it is running again, the furnace is started under heavy load, and the expansion of the boiler water just reaches the target water level Range, without manual intervention on the water level repeatedly.
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:
