Routine Operation and Maintenance of Air Cooled Condenser Power Plant

The core operational points for daily operation and maintenance of air cooled condenser power plant cover the entire process of daily inspection, cleaning and maintenance, troubleshooting, and energy efficiency optimization to ensure long-term stable equipment operation:

1. Core Items of Daily Inspection

Appearance and Leakage Inspection: Inspect the overall appearance of the equipment to confirm there is no corrosion or deformation. Focus on checking pipe bundles, pipelines, valves, flanges, etc., to confirm there are no media leaks or loose connections.

Fan System Inspection: Confirm that all axial fans operate without abnormal noise or severe vibration, that the fan blades are intact and not deformed, and that the fan supports are secure and the foundations are not loose or weathered.

Operating Parameter Monitoring: Monitor the motor's operating temperature and current in real time, confirming that the values are within the equipment's rated range. Simultaneously verify the accuracy of the control system and various pressure and temperature instruments.

Auxiliary Component Inspection: Confirm that the fan belt is not damaged, that the air-cooling system's water pumps are operating normally, and that the electrical junction boxes are free of water ingress and poor contact.

2. Cleaning and Maintenance Practical Methods

Surface Descaling: For dust and debris on the fin surface, use a soft brush to sweep along the fin direction, combined with compressed air to blow clean from the inside out. For oil stains, use a neutral descaling agent with low-pressure water rinsing, avoiding direct high-pressure water jets which can deform the fins.

Internal Descaling: For scale inside the heat exchange tubes, choose the appropriate solution based on the material: Mechanical descaling uses a flexible shaft tube cleaner to rotate and scrape away scale, combined with circulating water to remove contaminants; Chemical acid washing uses a weak acid descaling agent to circulate and clean for 24 hours, followed by repeated rinsing with clean water until no residue remains; an electronic magnetic water heater can be installed routinely to prevent scale buildup without affecting operation.

3. Quick Troubleshooting for Common Faults

Equipment Leakage: Cracks/sand holes in the coil, U-shaped weld failure; locate the leak point and repair welding; replace the corresponding component if the damage is severe.

Pipe Blockage: Weld slag or foreign objects entering the pipes cause blockage; use high-pressure nitrogen to blow away the blockage; replace the corresponding pipe section if the blockage is severe.

Sudden drop in heat exchange efficiency: Fin buildup and poor ventilation; immediately stop the machine, clean the fins, check for obstructions in the air intake channel, and restore ventilation.

Motor malfunction: Insufficient bearing lubrication or overload operation; replenish/replace bearing grease, investigate the cause of the overload, and adjust the operating load.

4. Energy Efficiency Optimization Operation Strategy

Dynamic Adjustment: Adjust the number of operating fans and their speed in real time according to ambient temperature and unit load to reduce fan power consumption while meeting vacuum requirements.

Freezing Prevention: During low-temperature periods in winter, prevent freezing and cracking of the tube bundle by zoning radiators, adjusting fan direction, and using auxiliary heating.

Regular Calibration: Calibrate instruments and speed control mechanisms quarterly to ensure accurate parameter control and avoid unnecessary energy waste due to control deviations.
