Electric Power Industry Systems
For over a half a century,
Nash Engineering's systems have been the products of choice in steam cycle and
geothermal power plants throughout the world. Reducing the effects of air
leakage into the condenser, our vacuum systems save millions of dollars worth of
fuel every day.
Self-contained
condenser exhauster packages in steam cycle plants reduce inward air
leakage, lower turbine backpressure, improve heat rates, and reduce generating
costs. They provide sufficient SCFM capacity to compensate for circulating water
temperature changes caused by seasonal climate variations.
They are designed to:
-
Perform reliably over
the entire condenser operating range
-
Operate simply and
automatically
-
Hold the condenser at
the best vacuum during unexpected transients of air leakage
Gas loading from
underground geothermal wells is huge compared to fuel-fired steam plants, and
anticipating future steam conditions requires experience. Nash's extraction
systems are the logical and efficient method of condenser gas removal, because
they:
-
Compensate for field
changes
-
Insure the efficient
use of steam
-
Prolong Geothermal
Well life
The Hybrid Systems,
consisting of a single stage liquid ring vacuum pump and steam jet air ejector,
are the standard against which other products are measured and we are the only
manufacturer of both steam jets and stainless steel liquid ring vacuum pumps.
Nash also provides systems
for other power plant applications such as:
Paper Industry Systems
Nash Engineering's water
removal experts have over 60 years of worldwide application and process
experience This experience has been gained from hundreds of new machine
installations, rebuilds and upgrades in the paper industry. Six generations of
vacuum pumps, significant contributions to TAPPI standards, numerous patents on
paper machine equipment, applications, and processes. These are just a few of
the reasons that we are the world's leading supplier of paper machine
de-watering equipment.
We combine our knowledge of
the paper-making process, vacuum and felt conditioning systems with how they
affect heat and energy costs. This knowledge coupled with our design, selection,
and start-up capabilities, assure you of optimum production and sheet quality.
Nash can provide all the
major vacuum pump and felt conditioning components plus auxiliary equipment
including: low vacuum fans, filters, low NPSH pumps, pre separators, cooling
towers, valves, control devices, and other accessories. We will also specify
pipe sizes and layout. With this, Nash provides you with an unrivaled source of
products and services for the wet end of your machine.
