Compact Analyzer Combines On-line
Silica and Phosphate Monitoring
The characteristics of power plant water/steam throughout the
entire electrical generating process have a major impact on overall
plant performance. Two critical areas of focus are controlling silica
deposition on expensive assets and, where used, ensuring proper
dosage of phosphate to prevent corrosion. With reliable, actionable
insights from on-line silica and phosphate monitoring, plant
personnel gain confidence to take the necessary actions to extend
asset lifetime, while avoiding expensive maintenance.
The importance of on-line analytics
With power plants facing a multitude of challenges ranging from
tightening budgets to increasing flexible operation, simplifying the
complex world of water chemistry is of utmost importance. Proper
monitoring and control throughout the water/steam cycle enable
plants to maximize reliability, safety and profitability. It begins with
setting the foundation-monitoring the right chemicals at the right
time and under budget. This has led to the importance of chemicalspecific
analyzers, including those for silica and phosphate, to
provide dependable, automated, on-line measurements.
Proven standards meets value-driven innovation
Optimizing established colorimetric technology, the METTLER
TOLEDO Thornton 2850Si Silica Analyzer provides dependable, low
ppb level silica measurements. With each measurement cycle, it rezeroes
itself on the sample to correct for changes in sample clarity
or the analyzer's optics. In addition, configurable auto-calibration
timing with standard solution level status provides increased
operator confidence.
Raising the bar with unprecedented functionality, the 2850Si
Silica Analyzer addresses monitoring needs of both silica and
phosphate, when applicable, in boiler water. Previously requiring
separate analyzers, the 2850Si provides the ability to determine
the silica and phosphate concentrations simultaneously. With the
The 2850Si Analyzer offers 3-in-1 functionality with on-line silica and phosphate
monitoring, plus an integrated multi-stream sequencer.
2850Si, plant personnel are no longer forced to choose between
the high cost of managing a separate analyzer or the more timeintensive,
manual grab sampling process.
The 2850Si Silica Analyzer integrates Intelligent Sensor
Management (ISM) technology for continuous performance
verification through predictive monitoring. ISM is based on decades
of experience with METTLER TOLEDO sensor performance in
various operating environments, and the impact of those conditions
on the health and maintenance frequency of the measurement
point.
A small, yet robust enclosed or flat panel
mounting design enables the 2850Si Silica
Analyzer to combine reliability while meeting
today's rigorous power plant operation challenges.
Personnel can add flexibility with built-in, multistream
sampling and faster measurement speeds,
reduce downtime with low reagent consumption
and ISM-driven predictive diagnostics, and improve
efficiency by saving valuable panel space with
integrated phosphate measurement capability and
simple, infrequent maintenance.
Unprecedented challenges in the power industry
The 2850Si uses the standard colorimetric measurement technique and common reagents
for silica and phosphate monitoring.
