Flue Gas Cooler Technical Specifications | |||
Heat Transfer Core | Material | Carbon Steel (Q235B), Stainless Steel (304/316L), ND Steel (acid-resistant), Corten Steel | For high-sulfur flue gas, recommend ND steel or 316L; carbon steel + coating for mild corrosion. |
Tube/Plate Dimensions | Tubular: Φ25mm–Φ50mm; Plate: 0.6mm–2mm thickness | Plate designs require dust-cleaning considerations. | |
Structure Type | Shell & Tube, Heat Pipe, Plate (with cleaning design) | Tubular or heat pipe preferred for high-dust applications. | |
Flue Gas Side | Inlet Temperature | 150°C–600°C | For >500°C, use heat-resistant alloys or refractory lining. |
Outlet Temperature | 60°C–200°C | Must avoid acid dew point temperature (to prevent corrosion). | |
Pressure Resistance | Atmospheric–0.5MPa | Positive-pressure systems require enhanced sealing. | |
Coolant Side | Coolant Type | Water (closed/open loop), Air, Thermal Oil | Use coated tubes or filters for poor water quality. |
Operating Pressure | Water: 0.4MPa–2.5MPa; Air: Atmospheric | Closed-loop water systems need pressure-rated design. | |
Performance | Heat Transfer Area | 10m²–5000m² | Calculated based on flue gas flow and temperature drop. |
Heat Recovery Efficiency | 40%–85% | Depends on temperature difference and flow ratio. | |
Cleaning System | Cleaning Method | Sonic Horns, Shock Pulse, Mechanical Rapping (optional) | Mandatory for high-dust flue gas (e.g., coal-fired boilers). |
Cleaning Frequency | Auto mode: Every 2–8 hours; Manual mode adjustable | Correlates with dust concentration. | |
Corrosion Protection | Surface Treatment | Aluminization, Enamel Coating, Glass Flake Lining | For high-sulfur/high-humidity flue gas. |
Drainage Design | Sloped layout (≥3°) or Bottom Ash Hopper + Auto Discharge Valve | Prevents condensate accumulation. | |
Structural Materials | Casing Material | Carbon Steel (lined), Stainless Steel, PP/FRP (corrosion-resistant) | Post-WFGD flue gas recommends FRP or 2205 Duplex Stainless Steel. |
Standards & Certs | Manufacturing Standards | GB/T 150 (Pressure Vessel), NB/T 47047 (Heat Pipe), ASME (export projects) | Material Certificates (MTC) and pressure test reports required. |
Applications | Typical Uses | Coal/Gas Boiler Waste Heat Recovery, Waste Incineration, Metallurgy/Chemical Exhaust | Material selection based on flue gas composition (SOx, NOx, dust). |
Custom Options | Optional Features | Bypass Duct, Online Monitoring (Temp/Pressure/Corrosion Probes), Modular Design | For complex conditions or space constraints. |
