Water Box Priming

Condenser Water Box & Circulating Water Pump Priming Systems

To ensure maximum efficiency of your condenser LYNN offers a complete line of Pre-engineered and Custom Water Box Priming Systems for the power industry. A LYNN Water Box Priming System gets your circulating water pumps started and keeps the condenser’s water box evacuated of air.

LYNN Water Box Priming Systems are an economical and efficient way to get peak performance from your condenser.

The flow of water through the condenser is typically designed to take advantage of the natural siphon effect between the inlet water surface level and the lower discharge water level. By maintaining this siphon effect, the circulating water pumps don’t need to lift the water to the top of the condenser; they only need to be designed to overcome the friction loses, greatly reducing the power requirements of the circulating water pumps. In addition to the initial priming, a LYNN Water Box Priming System removes dissolved gases that come out of solution in the cooling water, preventing trapped air and other non-condensables from accumulating in the cooling water loop.

Having a system flooded and filled at start-up doesn’t mean it will operate at peak performance. The negative pressure at the
discharge piping causes air to leak into the discharge piping and water box. Due to the operating temperature and pressure, even in a tight system air and other non-condensables will come out of solution creating air pockets. This accumulation of air will have two effects. 1. It will expose the top condenser tubes which will reduce the cooling efficiency of the condenser and 2. Over time, air accumulation will eventually break the siphon causing excessive loading and reduced flow capacity in the circulating water pump.

Water Box Priming Systems are furnished as a fully assembled and tested skid mounted duplex system (100% duty back-up ).

System Features Include:

• Heavy duty liquid ring vacuum pumps for virtually no maintenance.
• Ideally suited for handling saturated gases and liquid carryover
• Liberally sized Horizontal or vertical vacuum receiver for reduced pump cycling.
• Vacuum pumps sized for 100% duty backup.
• Pressure controlled automatic system operation with high water level alarm/shutdown protection
• Controls for automatic system operation with options for alternating or specified lead-lag duty.
• Wide selection of materials for pump and component equipment are available to suit any application conditions.
• Priming valves with available optional system control features
• Piping per ANSI B31.1
