API 661 Forced Draft Air Cooled Exchanger Optimal Flow Cooling for Power Plant
Product Description
Standard Compliance: Fully certified under API 661 and ASME Section VIII Division 1.
Core Materials: SA213-TP316L stainless steel or seamless carbon steel with bimetallic aluminum high-fins.
Key Benefits: Eliminates 100% of process water consumption and mitigates cyclic thermal stress.
Structure: Heavy-duty modular A-frame or horizontal configuration for continuous 24/7 operation.
API 661 Forced Draft Air Cooler for 300MW Desert Power Plant
Process Challenges & Requirements
Extreme Location: Project based in an arid Middle Eastern desert with ambient temperatures reaching 52°C.
Zero Water Policy: Severe water scarcity prohibited the use of traditional water-cooled towers or evaporative systems.
Thermal Shock: Primary loop fluid entered at 180°C, creating severe risk of thermal fatigue cracking at the joints.
Advantage
Engineering Solution: Forced Draft
Ground-Level Access: Fans and mechanical drives are mounted at the bottom, enabling safe, platform-free maintenance during continuous operation.
Extended Motor Life: Moving components operate strictly in the cool, ambient incoming airstream, protecting electrical insulation from high-temperature exhaust.
Parametric Technical Specifications
Certifications: Formally stamped with ASME "U" Certification and engineered to API 661 parameters.
Robotic Tube Jointing: Tubesheet joints feature robotic seal welding combined with strength expansion, zero-leakage verified under 15 MPa hydrostatic pressure.
Stress Relief (PWHT): Thick-wall header plate cutouts processed via 18-meter precision laser cutters, followed by mandatory Post-Weld Heat Treatment to eliminate residual stresses.
Operational Outcomes
Water Conservation: Saves over 100 metric tons of process water per hour with zero chemical discharge penalties.
Optimal Flow Distribution: Computerized aerodynamic modeling restricted airflow velocity variance across the bundle face to under 5%, stabilizing turbine backpressure even during peak solar radiation.
