Abstract
A method of substantially preventing contaminants from entering a condenser adapted for use within a steam generating system. A condenser is provided. Steam or a combination of water and steam is passed into the condenser, the condenser operating in a normal mode if a pressure in a control area is equal to or greater than a predefined pressure and operating in a non-normal mode if the pressure in the control area is less than the predefined pressure. An inert gas is injected into the condenser if a pressure in the control area is less than a holding pressure, the holding pressure being equal to or greater than the predefined pressure.

A method of substantially preventing contaminants from entering a condenser adapted for use within a steam generating system, the method comprising:
- providing a condenser;
- passing steam or a combination of water and steam into the condenser, the condenser operating in a normal mode if a pressure in a control area is equal to or greater than a predefined pressure and in a non-normal mode if the pressure in the control area is less than the predefined pressure;
- monitoring the pressure within the control area to determine if the pressure within the control area drops below a holding pressure, the holding pressure being equal to or greater than the predefined pressure;
- and
- injecting an inert gas into the condenser if the monitored pressure in the control area is less than the holding pressure.
A condenser system adapted for use within a steam generating system comprising:
- a condenser adapted to receive steam or a combination of water and steam, the condenser operating in a normal mode if a pressure in a control area is equal to or greater than a predefined pressure and in a non-normal mode if the pressure in the control area is less than the predefined pressure;
- and
- pressure maintenance apparatus for sensing a pressure in the control area and causing an inert gas to flow into the condenser if the pressure in the control area is less than a holding pressure, the holding pressure being equal to or greater than said predefined pressure.
