Company Information

A:Fangkuai was established on January 8, 1998 with a registered capital of over 100 million RMB. We are a High-tech enterprise engaged in researching,manufacturing and selling clean fuel boiler and clean combustion boiler. We are Class A boiler manufacturer, one of the best boiler manufacturers with superior digital processing ability. We believe you can find our products in different countries and our success owes to the state-level R&D Center, Test Center and 140,000 square meters Production Base.





B:The unique all-condition laboratory in China; Qualification of Grade A boiler manufacturing; Qualification of first class boiler installation. Fangkuai has the greatest strength in boiler industry.  




C:Fangkuai has invested in a National center to research and test clean-fuel boiler and built a cooperation base of industry and school with Tsinghua University and Xi 'an Jiaotong university. Numerous practical tests settled into the most comprehensive data of boileroperation and innovative patented technology.

Core Technology

A:Ultra speed smoke cooling tube

Ultra speed smoke cooling tube, high efficiency, energy saving and advanced condensing technology guarantee high efficiency of energy utilization. Through latent heat absorption of vaporization in the exhaust air, energy is utilizing efficiently. It saves energy and improves thermal efficiency.  


B:Integrated Condensation Technology

The boiler structure has significant influence on thermal efficiency. Fangkuai explores a kind of one-piece structure which has greatly improved the boiler thermal efficiency.Fangkuai condensing technology is to use the efficient heat released by the exhaust smoke including sensible heat released by the smoke and latent heat released by the condensed steam, so as to improve the boiler's thermal efficiency.After numerous tests and experiments, Fangkuai has accumulated the industry's leading integration and condensation technology.


C:FGR technology

FGR technology is recycling a part of exhaust smoke(temperature of 150℃-350℃) back into the burner to complete secondary combustion along with a lower furnace temperature. Thus, NOx emission can be reduced to a great extent. In the process of boiler operating, the combustion process of natural gas changes all the time. Many elements can affect this process, such as gas quantity, FGR flue gas temperature, oxygen levels in the exhaust smoke, etc. Tiny changes of these factors will affect the NOx emission.Low emission has always been our research direction. The development and application of Fangkuai FGR technology can guarantee less than 30mg/Nm3 NOx emission for your boiler.
