Abstract:
1. An apparatus for the purging of hydrogen cooling gas from a turbine, the apparatus comprising: a) a first and second source of liquid carbon dioxide in fluid communication with a flow manifold, b) the flow manifold in fluid communication with a vaporizing heater, c) the flow manifold comprising a device configured to switch the source of liquid carbon dioxide into the vaporizing heater from the first source of liquid carbon dioxide to the second source of liquid carbon dioxide or from the second source of liquid carbon dioxide to the first source of liquid carbon dioxide, d) the vaporizing heater configured to receive the liquid carbon dioxide from the flow manifold and vaporize the liquid carbon dioxide to a gaseous state, e) an outlet in fluid communication with the vaporizing heater, the outlet configured to deliver gaseous carbon dioxide from the vaporizing heater, f) one or both of: g) the controller configured to h) a temperature sensor configured to measure the temperature of the gaseous carbon dioxide produced by the vaporizing heater, wherein the temperature sensor is in electronic communication with the controller and adapted to transmit the temperature of the gaseous carbon dioxide to the controller.
