  • Patent number: 4004424
    Abstract: Steam is removed from the steam cycle of a turbine when the back pressure on the turbine exceeds a predetermined level. Heat is then extracted from the removed steam and dissipated in a cooling tower of a cooling system for the turbine's condenser. Increased temperatures in the cooling tower augment thermal fan action, resulting in lower coolant temperatures and limiting the back pressure on the turbine. When the back pressure on the turbine decreases to an acceptable level, the steam is redirected into the steam cycle.In a preferred embodiment, heat is extracted from steam by passing the steam through the high temperature coil of a vapor-absorption generator. The high temperature vapor formed in the generator transfers the heat to the heat dissipating surfaces of a cooling tower or into heat-exchange relationship with an exhaust coolant discharged from a steam condenser.
