Two decades making industrial combustion more efficient

As a National High-Tech Enterprise and a "Specialized & Sophisticated" (SRDI) enterprise, Langfu has spent over two decades in environmental technology, accumulating nearly a hundred national patents and building a full value-chain service system that spans industrial energy saving, clean-combustion optimization, and comprehensive environmental remediation. Every stage — from on-site diagnosis and scheme design through equipment retrofit and long-term operation — is executed by our own engineering teams, with a service footprint reaching China's major industrial clusters.

Langfu's core capability is bridging the gap between laboratory research and production-floor reality. For gas kilns and boilers, we have developed a suite of proprietary technologies — multi-stage resonance activation, catalytic combustion, low-NOx burners, energy-saving cutting nozzles and black-body radiation coatings. The unifying principle: achieve more complete fuel combustion and more efficient infrared heat transfer by optimising gas-molecule activation and combustion-field thermal radiation structure, without touching the boiler vessel itself. Average field-verified savings run 4–15%, with a peak measured result of 19.6%.

Langfu maintains long-term research partnerships with Zhejiang University, China University of Mining and Technology, Chongqing University and Nanjing University of Science and Technology, jointly advancing combustion efficiency and coordinated pollutant control. This academia-industry model ensures every product generation is grounded in peer-reviewed science — not accumulated rule-of-thumb — and continually converts research breakthroughs into quantifiable cost and emissions reductions for clients.

Langfu's retrofit projects span clients across ceramics, glass, steel, chemicals, food processing and other industries nationwide. Our commitment is simple: baseline data is collected before every project, post-retrofit measurements are taken under identical operating conditions, and the resulting savings report is fully traceable. No ambiguous promises — every figure can be checked.
