with power sector engineers and operators, we are able to push the limits of

In order to
increase the availability, operational performance and reliability of turbine
condenser vacuum plants, the dynamic relationship between the vacuum pumping
system, condenser performance and turbine back pressure is an important factor
in the design requirements and needs careful appraisal when considering overall
The air load
from the turbine condenser system is saturated with vapour: liquid ring pumps
are ideal for handling high vapour loads as much of the vapour will be
condensed at the pump suction (by the direct condensing action of the inlet
water spray or contact with the pump seal water). This condensing reduces the
total volume to be handled by the pump, which is a significant advantage when
compared to other pumping technologies.
conveying of fly ash recovered by the Electrostatic Precipitator, ash is
collected in hoppers at the base of the ESP and is then conveyed to a storage
facility or loading silo. Liquid ring vacuum pumps are tolerant to ash carry
over and the single stage pump construction ensures optimum power at pressures
required for effective conveying.
to handle wet gases without any detrimental effect makes liquid ring vacuum
pumps ideal for condenser waterbox priming applications. Waterbox priming
serves two functions: to create a siphon effect reducing the amount of power
required to start the main cooling water pumps; and to ensure maximum condenser
cooling efficiency by preventing accumulation of air in the upper parts of the
cooling tube bundle.
