The high pressure feedwater heater is a high-efficiency, energy-saving product that utilizes steam extracted from the steam turbine to heat boiler feedwater, thereby raising the feedwater temperature. Typically, the high pressure feedwater heaters designed and manufactured by our company feature a U-tube structure and are matched with units of 300MW and below.
Features:
1. The structure adapts to variations in generator parameters, ensuring safe and reliable operation, with resistance to vibration, erosion, and leakage, as well as excellent self-sealing performance;
2. High heat transfer efficiency, enhancing the heat transfer coefficient of the tube system, adapting to unit peak-shaving operation, and maximizing the heat transfer efficiency of the equipment's own heat transfer surface;
3. Easy maintenance: the equipment body features an all-welded structure, and the manhole adopts a self-sealing design for quick disassembly and convenient maintenance;
4. Advanced process technology, employing a weld-then-expand procedure; tube-to-tubesheet welds are performed using all-position argon arc welding, and tube expansion utilizes a liquid bag expansion method, ensuring leak-free tube joints.
