Cryogenic - Optimized Wound Tubular Heat Exchanger for Power Generation & Low - Temp Storage
For power generation applications, the energy - efficient spiral wound tubular heat exchanger offers significant advantages. It is designed to recover waste heat from exhaust gases or steam, improving the overall thermal efficiency of power plants. The tightly wound tube structure increases the turbulence of the fluids, enhancing heat transfer by reducing the thermal boundary layer.
Constructed from high - temperature - resistant materials like stainless steel and nickel alloys, it can operate under extreme conditions with temperatures up to 1000°C and pressures of 8 MPa. In combined - cycle power plants, it effectively transfers heat between different working fluids, increasing the power output by up to 15%. During the manufacturing process, computer - controlled winding machines ensure consistent tube spacing and tightness, optimizing its performance and contributing to sustainable power generation.
Product Details
Basic Information
◆ Place of Origin: China
◆ Brand Name: [Customizable, e.g., CryoTech]
◆ Certification: ASME BPVC, ISO 9001, NBIC
◆ Model Number: CWHX - P2025
Product Overview
◆ Engineered for cryogenic storage and power generation, this wound tubular heat exchanger uses nickel - alloy tubes to resist thermal shock. It outperforms standard shell - and - tube designs in low - temperature applications and recovers waste heat in power plants, boosting thermal efficiency. Ideal for cryogenic tanks, LNG facilities, and combined - cycle power plants.
Key Specifications
◆ Construction Materials
Tubes: Nickel - alloy (e.g., Inconel 625) for cryogenic resilience; stainless steel 310S for high - temp power plant use. Resists thermal shock (- 196°C to 1000°C) and corrosion from exhaust gases/steam.
Shell: High - strength carbon steel (optional: duplex stainless steel for extreme corrosion). Ensures structural integrity under 8 MPa pressure.
◆ Performance Parameters
Temperature Range: - 196°C (cryogenic storage) to 1000°C (power plant exhaust).
Pressure Rating: Up to 8 MPa (handles high - pressure steam in power cycles).
Heat Recovery Efficiency: Reduces waste heat loss by 40%, improving power plant thermal efficiency by 15% (via enhanced turbulence in wound tubes).
Design & Functionality
◆ Cryogenic Resilience
Nickel - alloy tubes eliminate thermal shock risks in cryogenic applications (e.g., LNG storage, liquid nitrogen systems). The tightly wound structure maintains flow stability at - 196°C, preventing tube fractures common in standard designs.
◆ Power Plant Waste Heat Recovery
In power generation, the spiral - wound tubes increase fluid turbulence, reducing thermal boundary layers. This enhances heat transfer from exhaust gases/steam to working fluids (e.g., water, thermal oil), recovering waste heat to boost power output by 15%.
Application Areas
◆ Cryogenic Storage & LNG Facilities
LNG Regasification: Preheats cryogenic LNG to gaseous form using ambient heat, reducing energy use in regas plants.
Liquid Gas Storage: Maintains stable temperatures for liquid nitrogen, oxygen, and argon tanks, preventing phase changes.
◆ Power Generation
Combined - Cycle Plants: Transfers heat between high - temp exhaust (1000°C) and steam/water loops, improving cycle efficiency.
Waste - to - Energy Facilities: Recovers heat from incinerator exhausts, converting waste heat to electricity.
