Abstract
The present invention comprises a method and device for deterring the freezing within a condenser by preventing critical pressure differentials from building up between the exhaust steam header and the air ejector systemy. The means for regulating pressure in the air ejector system prevents the pressure difference between the turbine exhaust and the air ejector system from being great enough to carry condensate through a condensing tube into an air ejector system.
