Product DescriptionProduct DescriptionAir Preheater Technical SpecificationsDesign TypeConfigurationRegenerative (Rotary), Recuperative (Tubular/Plate)Rotary: high efficiency; Tubular: lower maintenance.Flow ArrangementCounter-flow, Cross-flowCounter-flow optimizes heat recovery.PerformanceDuty50–500 MW (Power Plant Scale); 1–50 MW (Industrial)Based on boiler/furnace capacity.Air Temp Rise150°C–400°CInlet: ambient; Outlet: 300°C (typical coal-fired boilers).Flue Gas Temp Drop150°C–350°C → 90°C–150°CMinimizes acid dew point corrosion risk.Efficiency Gain5–15% (Boiler Efficiency Increase)1% efficiency gain ≈ 0.5% fuel savings.MaterialsHot End (400°C)Corten Steel, SS309, Inconel 625Resists oxidation/high-temp corrosion.Cold End (200°C)ND Steel (09CrCuSb), Enamel-Coated Tubes, 316L + PTFE CoatingCritical for HSO dew point corrosion protection.Baskets (Rotary)Carbon Steel (High-Temp Zones), Duplex 2205 (Corrosion Zones)Modular replaceable sections.ConstructionTubular DesignTube OD: 40–80 mm; Thickness: 2–6 mmStaggered layout for gas turbulence.Rotary DesignDiameter: 5–25 m; Height: 1.5–3 mSector plate division: 12–24 sections.Leakage RateTubular: <2%; Rotary: 5–10% (with sealing system)Advanced seals reduce rotary leakage to <5%.ThermalHeat Transfer Area5,000–150,000 m2Rotary units offer higher surface density.Gas-Side ΔP0.5–2.5 kPaImpacts induced-draft fan power.Air-Side ΔP0.8–3.0 kPaAffects forced-draft fan sizing.Cleaning SystemsSoot BlowersRetractable Steam/Air, Sonic Horns, Water Washing PortsSteam: 8–12 bar; Frequency: 2–4 times/shift for coal-fired.Ash HandlingHopper + Rotary Valve (Tubular); Ash Dumping System (Rotary)Fly ash removal capacity: 1–20 T/h.Sealing (Rotary)Radial/Axial SealsSpring-Loaded Alloy Steel, Ceramic FibreAuto-adjusting seals for thermal expansion.Sealing Air System200–1000 m3/h @ 2–5 kPaCreates air barrier to reduce gas leakage.Drives (Rotary)Main Drive0.5–10 kW Motor + Gearbox (0.1–2 rpm)Variable frequency drive (VFD) for speed control.Auxiliary DriveManual/Electric (0.1 rpm)For maintenance during main drive failure.StandardsDesign CodesASME Sec. VIII, EN 12952 (Boilers), GB/T 16507, TRD 800Compliance with pressure part regulations.Emission ControlISO 13705 (Petroleum Refineries), MACT Standards (EPA)Supports NOx/SOx reduction systems.ApplicationsIndustriesCoal/Gas Power Plants, Refineries, Cement Kilns, Chemical Process HeatersCritical for waste heat recovery.Optional FeaturesUpgradesCold-End Corrosion Monitoring Probes, Online Leakage Detection, Hot Air Bypass DampersBypass dampers protect during cold starts.Hybrid SystemsCombines with Economizer or Flue Gas CondenserBoosts overall efficiency by 3–8%.SpecificationApplied fieldsPetroleum, Metallurgy ,Industrial, Chemical, Pharmaceutical etc.Design pressure30 MpaDesign temperature≤400℃Fin MaterialAluminum,carbon steel, stainless steelTube materialCarbon steel,stainless steelDesign service lifemaxDelivery timewithin 60 days unless specified speciallyPackingExporting seaworthy standard packageShipping PortQingdao port, Shandong provinceCompany ProfileHenan Tuofang Energy Saving Technology Co., Ltd. is a professional supplier of finned tubes and energy-saving devices in Henan Province.
