As a leader in vacuum technology, today Edwards has grown within the power industry from pioneering work in developing equipment for the early power stations, to the supply of sophisticated vacuum systems for thermal, nuclear and even solar-powered power plants. 

By working with power sector engineers and operators, Edwards is able to challenge the limits of vacuum system design, creating solutions to meet the demands of increasingly challenging applications.

The efficiency of steam turbines is an important part of electricity generation. Edwards’ liquid ring vacuum pumps play a vital role in maximising efficiency by removing excess air from the system. On exiting the turbine, steam is condensed either by a water or an air-cooled condenser, creating a vacuum inside the turbine and therefore increasing efficiency. To maintain this vacuum, air and other non-condensable gases (that leak into and build up within the condenser) must be extracted. Liquid ring vacuum pumps are used worldwide in this critical application.

Edwards’ liquid ring pumps are used on condenser waterbox priming, to ensure that they operate at optimum cooling performance; the pumps also perform a deaeration duty, continuing to remove accumulated air and noncondensable gases from the condenser cooling water.

Liquid ring pumps are also utilised on exhaust gas treatment processes for fly ash handling and flue gas desulphurisation.
