The Power To Deliver Solutions

FPB Full Premixed Combustion Technology

Our FGR+SCR hybrid combustion technology achieves 99.2% fuel efficiency through aerodynamically optimized venturi premixing chambers, ensuring air-gas stoichiometric ratios within ±1.5%. This innovation powers Fangkuai’s Ultra-NC series boilers, delivering NOx emissions as low as 8.7 ppm (≈16mg/m³) – 47% below Beijing’s 30mg/m³ limit (DB11/139-2021). Certified by TÜV Rheinland and ASME PTC 4.1, the system reduces carbon monoxide output to under 5ppm through ceramic-foam flame retention grids.

The multi-stage porous metal fiber combustion surface eliminates thermal stratification, maintaining less than 20°C temperature variance across burner heads to suppress NOx/CO formation. Operators control combustion intensity (20-100% load) via 4-20mA analog signals with ±0.8% modulation accuracy. Field data from Sinopec’s 12MW steam project shows 92% turndown capability while sustaining 108.3% combustion efficiency (LHV basis), cutting annual gas consumption by 1.2MMBtu per unit.

FGR Gas Recirculation Technology

Our staged FGR system (External Type II per NFPA 86 standards) reduces NOx emissions by recirculating 15-30% of exhaust gas (160-260°C) into primary combustion zones via corrosion-resistant 316L stainless ducts. This lowers oxygen concentration to 17.5-18.2 vol% (vs. ambient 20.9%), suppressing adiabatic flame temperatures below 1,450°C to inhibit thermal NOx formation. Simultaneously, the 3D-printed ceramic matrix heat recuperator absorbs 1.8MJ/Nm³ of thermal energy, achieving dual NOx reduction through chemical kinetics and thermodynamic pathways.

Field data from ExxonMobil’s 24MW boiler retrofit shows 82% NOx reduction (from 120mg/m³ to 22mg/m³) at 18% FGR rate with burner turndown to 25% load. The system’s ASME PTC 4.1-2021 certified performance maintains CO below 9ppm despite oxygen-lean conditions, while integrated SCR catalysts further cut NOx to under 5mg/m³ for compliance with EPA 40 CFR Part 60 Subpart Db. Such hybrid configurations now serve 1,300+ industrial units globally, including BASF’s 45MW steam networks achieving 91% annual operational availability.

FPB Full Premixed Combustion Technology

Our flue gas condensing heat recovery system utilizes 20-40°C deionized water in counterflow plate exchangers (EN 12753 certified), cooling exhaust gases from 160°C to 48°C. This process extracts 2.8MJ/Nm³ latent heat through vapor phase transition on corrosion-resistant 2205 duplex stainless steel surfaces, while recovering 1.2MJ/Nm³ sensible heat via gas-liquid temperature differentials. The integrated thermal bridge transfers 94% of captured energy to preheat feedwater, elevating boiler efficiency to 108.3% (HHV basis) in BASF’s 15MW steam system retrofit.

The space-saving modular design (footprint 3.2m² vs conventional 8.5m²) employs 316L stainless steel spiral finned tubes with 12.7mm fin height and 3.2 fins/cm density. This configuration achieves 18.6m²/m linear heat transfer area while maintaining flue gas side pressure drop below 120Pa (ASHRAE 84-2020 tested). Compatible with standard natural gas burners, the system demonstrates 0.85% efficiency degradation per 10,000 operational hours in Shell’s LNG terminal application, outperforming traditional shell-tube designs by 23% in longevity.

PLC Automatic Control System

Our patented Ultraten heat exchanger employs helical finned tubes fabricated from titanium-molybdenum alloy , achieving 94.6% thermal efficiency through counterflow condensation. The system cools 260°C flue gas to 48°C within 0.8-second residence time, recovering 4.2MJ/Nm³ latent heat via phase-change condensation on laser-textured surfaces . Certified under ASME PTC 12.5-2022, this design elevates boiler system efficiency to 108.3% in Sinopec’s 18MW steam network retrofit, cutting flue gas thermal losses to 3.8% while maintaining 22-month maintenance intervals – 35% longer than conventional shell-tube units.
