Vacuum Pumps and Compressors for the Electric Power Industry

NASH Electric Power Generation Vacuum Systems Condenser exhauster systems assure maximum power availability Nash self-contained condenser exhauster packages in steam cycle plants efficiently remove inward air leakage from the condenser. The effect is to provide lower turbine backpressure, improve heat rates and reduce generating costs. The packages consist of a two-stage liquid ring vacuum pump, air-liquid discharge separator, heat exchanger and associated controls. Cooling Water Two Stage NASH Vacuum Pump Spray Nozzle Heat Exchanger Partial Vapor Volume Total Volume From Condenser Total...
