POWER December 2020 - 36

EQUIPMENT SHOWCASE
POWER features a different power-related
equipment category in selected issues
throughout the year. This month's showcase
includes a variety of items used
in the power generation industry, from
pumps and valves to a silica analyzer and
laser measurement system.
Sulzer Takes Pressure Out of
Pump Operations
Major power station projects are among
today's most costly and complex engineering
challenges. As owners and
contractors strive to control capital
and operating costs while meeting demanding
build schedules, it's important
to have quality equipment. A modern
thermal power plant relies on dozens
of pumps for safe, efficient operation.
Those pumps cover a broad spectrum
of size and duty-cycle requirements,
from megawatt-scale boiler feed pumps
driven by steam turbines and giant cooling
water pumps, to an array of smaller
units handling condensate extraction and
a range of auxiliary functions. Selecting
and specifying each of these pumps can
have a big impact on overall project and
plant performance. Pumps are a significant
capital expense, so there is inevitable
pressure to keep up-front costs
down. At the same time, efficiency differences
of just a few percentage points
against corrosion. METTLER TOLEDO
Thornton's 2850Si silica analyzer provides
3-in-1 silica, phosphate, and multi-stream
measurements in pure and ultrapure waters.
With its innovative measurement
technique, a single 2850Si silica analyzer
does twice the monitoring with combined
silica and phosphate analysis for power
plant chemistry,
significantly
reducing
overall reagent consumption and operating
costs. The 2850Si's compact size,
driven by the need for 75% less reagent
volume compared to typical silica analyzers,
allows additional measurements to
be installed-optimizing valuable water
panel space. Monitoring of reagent usage
and tube/filter status with METTLER
TOLEDO's Intelligent Sensor Management
(ISM) technology enables proactive
inventory and service planning. To ensure

in large pumps can quickly translate into
meaningful changes in operating costs.
Sulzer's pumps are used in almost every
type of power plant, including nuclear,
solar, gas-fired, and biomass facilities.
Sulzer's comprehensive product offering
for the power generation sector includes
auxiliary pumps (Figure 1), all of which
perform important roles onsite. Sulzer,

Silica Analyzer with Combined
Measurement Technology
Silica monitoring is vital for the measurement
and control of contamination
in pure and ultrapure waters used in industries
such as power generation. Phosphate
treatment, often deployed within
power plant drum-type boilers, plays two
important roles-maintaining proper alkalinity,
and controlling scale build-up
for effective blowdown and protection

Clampseal Globe Valves for
Power Plants
Conval offers more than 12,000 configurations
of severe service Clampseal Y, angle,
and T-pattern globe stop, check, and stop
check valves (Figure 3) for power generation
applications. Many parts may be interchanged,
which means an entire power
plant can be supported with a small inventory
of parts. This reduces stocking costs,
procurement expenses, and maintenance
training time. The high-performance, U.S.made
forged valves are available in 1/2inch
through 4-inch sizes through ASME
#4500 Class with socket weld, butt weld,
threaded, clamp connector, flanged, or a
variety of special ends. Materials include
carbon steel SA105, low-alloy SA 182-F22,
and F91, stainless steel SA 182-F316, SA
182-F347, Inconel, and Monel. Features
include conformance to ASME B16.34;
pressure seal bonnet for maintainability;
quick-replacement packing chamber; single-piece
gland with integral gland wrench;
solid Stellite seating surfaces; and twoyear
warranty. Conval, Enfield, Connecticut

ing column machines, portal machines,
lathes, or a variety of other smaller
machines, the machine geometry is essential
for the quality of the product,
and also for the durability and reliability
of the machines. CENTRIC International
and Status Pro, CENTRIC's exclusive
partner in the Americas, offer the new
ProLine Laser Measurement System to
meet digitalization requirements. The
ProLine is a modern, wireless alternative
to dial gauges and granite rulers.
The ProLine 300 (Figure 4) consists of
a laser and various laser receivers. The
laser and receiver can be combined as
desired; this makes it possible to carry
out straightness, flatness, perpendicularity,
and parallelism measurements, as
well as leveling of entire machines. Conventional
measuring equipment such as
the granite angle is usually too small, too
heavy, and still has to be transported by

truck.
The ProLine 300 comes in a handy
case, is easily scalable in length, and offers
an accuracy of up to 1 micrometer/
meter. The software and a display unit,
which is extremely robust because it is
designed for industrial environments, enables
the operator to perform extensive
measurement point recording and documentation.
All important information of
the measurement is automatically saved
and a report in PDF and CSV format is
generated. All components are connected
via Bluetooth. CENTRIC International,
