Problems with condensing steam turbines
Thread Content
For vacuum pumping equipment, is a steam ejector better or a water ejector? They are used respectively for power generation and for driving water pumps, in complete condensers!
When the amount of dry air drawn is the same, a steam ejector consumes more energy than a water ejector; the energy-saving effect is even more significant when a water ejector with a long throat is used. Small units generally employ water ejectors, while large units use water ring vacuum pumps without exception.
Previously, the vacuum pumps used in condenser turbines were generally Siemens water ring vacuum pumps; nowadays, they are mostly being replaced by Roots vacuum units. By improving the vacuum level, it is possible to increase power generation while reducing the overall energy consumption of the equipment
