Control apparatus for air-cooled steam condensation systems
First Claim
1. A SYSTEM FOR CONDENSING STEAM IN A MIXING CONDENSER BY MEANS OF A LIQUID CONDENSATE OF THE STEAM, AND COOLING THE LIQUID CONDENSATE MIXTURE IN AN AIR COOLED HEAT EXCHANGER, SAID SYSTEM COMPRISING A CLOSED LOOP INCLUDING SAID CONDENSER, A CIRCULATING PUMP RECEIVING CONDENSATE MIXTURE FROM SAID CONDENSER FOR CIRCULATING SAID CONDENSATE MIXTURE, SAID AIR COOLED HEAT EXCHANGER COMMUNICATING, AT ITS INLET, WITH SAID PUMP, FLOW CONTROLLING MEANS COMMUNICATING BETWEEN THE OUTLET OF SAID HEAT EXCHANGER AND SAID MIXING CONDENSER PROXIMATE TO SAID MIXING CONDENSER, TRANSDUCER MEANS COMMUNICATING WITH THE LINE BETWEEN SAID HEAT EXCHANGER OUTLET AND SAID FLOW CONTROLLING MEANS TO PROVIDE A CONTROL SIGNAL PROPORTIONAL TO THE ABSOLUTE PRESSURE IN SAID LOOP AT THE HIGHEST GEODETIC LEVEL THEREOF, AND A SERVOMOTOR SYSTEM CONTROLLING SAID FLOW CONTROLLING MEANS AND RESPONSIVE TO SAID TRANSDUCER MEANS TO MAINTAIN THE PRESSURE AT THE HIGHEST GEODETIC LEVEL OF SAID LOOP AT A SUPERATMOSPHERIC VALUE, WHEREBY THE PRESSURE AT ALL POINTS IN SAID LOOP BETWEEN SAID PUMP AND SAID FLOW CONTROLLING MEANS IN THE DIRECTION OF CONDENSATE FLOW WILL BE MAINTAINED AT A SUPERATMOSPHERIC VALUE.
