PURPOSE:To enable to effectively prevent a high vacuum condition from being generated in a condenser, by providing a load-adjusting mechanism which adjust the load on an ejecting mechanism by recirculating gases ejected from the condenser from the discharging side of the ejecting mechanism to the ejecting side of the ejecting mechanism. CONSTITUTION:An ejecting mechanism 4 is provided which ejects noncondensing gases from the interior of the condenser 2 for a steam turbin 1 to maintain the interior of the condenser 2 at a required degree of vacuum and discharges the ejected noncondensing gases to the atmosphere by compressing the gases to a pressure of not lower than the atmospheric pressure. In the air ejector, the load-adjusting mechanism 14 is provided which adjusts the load on the mechanism 4 by recirculating the gases ejected from the condenser 2 from the discharging side of the mechanism 4 to the ejection side of the mechanism 4. Accordingly, a high vacuum condition is prevented from being generated in the condenser, without requiring any special device for taking the outside air into the vacuum region. |
