Reference Reference information: A hogger is a term someone somewhere thought would be a good description for a large air ejector that can be used to "bring up" (establish) vacuum on a condenser when little or no steam is being condensed, such as during start-up of a steam turbine. Once steam actually starts condensing the rapid decrease in volume that results from the steam condensing back into water actually is the "source" of the majority of the vacuum in the condenser. So, a large method of establishing and maintaining vacuum is no longer required. A holding air ejector is not a term I'm familiar with, but it might refer to an air ejector that is put into service after steam has started flowing through the turbine and is actually condensing in the condenser. It's probably put into service and then the hogger is taken out of service. The smaller holding air ejector is then doing exactly what it says: removing air and other non-condensable gases from the condenser, and assisting only marginally with maintaining the vacuum, since the condensing steam is the main source of the vacuum Reference: http://control.com/thread/1277275259 |
