Condenser ExhaustingCompatible Products

Condenser exhausting involves the removal of air and other non-condensable gases from the steam space of power plant condensers. The purpose of removing these gases is to maintain the lowest possible turbine backpressure. The equipment used for this application is crucial to the efficient operation of fossil fuel and nuclear power plants.


Condenser Exhauster Systems

TC/TCM Two Stage Vacuum Pumps

TC/TCM Two Stage Vacuum Pumps

The NASH TC/TCM liquid ring vacuum pumps are highly reliable and efficient. These pumps, with their integral two stage impeller, are able to condense process vapors and to recover or dispose of the vapors. Another benefit of these pumps is that they can attain vacuum levels down to 0.8" HgA (20mmHgA). This is approximately 40 percent lower absolute pressure than a single stage pump.

Flue Gas DesulfurizationCompatible Products

When flue gas is scrubbed to remove sulfur compounds, an aqueous slurry results. It is advantageous to remove the water from the slurry and handle only the solid material. This is done using vacuum filters. The NASH liquid ring pump's ability to handle carryover from these filters makes it the ideal choice for this application.

Fly Ash ConveyingCompatible Products

This application consists of pneumatically conveying fly ash from the precipitator hoppers to a central dry collection point under vacuum. The main advantage of this type of conveying system is that since the ash is being conveyed under vacuum, any leakage is of air inward, and not ash outward. The NASH pump is chosen for this application because of its ability to tolerate fly ash carryover into the pump.

Geothermal Gas RemovalCompatible Products

Similar in application to condenser exhausting, geothermal gas removal involves the removal of air and other non-condensable gases from the steam space of the condensers. However, in geothermal power plants, the steam used to drive the turbine is extracted from the earth and contains large amounts of corrosive gases. The gases must be removed from the condenser in the most efficient manner possible.
