Power Application Notes Index
The discharge of improperly treated industrial chemicals and fuel gas can have a major impact on the environment, posing a serious threat to public health. Concurrent with the global growth of manufacturing operations to keep pace with market trends, many countries are taking measures to deal with environmental problems.

| Yokogawa ensures a reliable heat and CO2 transfer system by using the standard GPRS
protocol. The exclusive use of webbased technology enables the market gardeners to go online
to order heat and CO2 and view information. |
| To make the most of the advantages of GPRS, Yokogawa's STARDOM FCN/FCJ intelligent RTUs
and FAST/TOOLS SCADA package have several functions that reduce the number of packets that
must be sent. This dramatically lowers communication fees. |
| Seawater leak detection is the post-condensation water quality management processes. Damage to the ion exchange resin, which deionizes the supplied water, is also monitored during this process, and both of these applications are executed by a conductivity analyzer.
|
Conventional dust measurement is
affected by dust buildup, deviation of the light
axis and necessitating frequent maintenance. The DT450G Dust
Monitor is not affected by dust accumulation and makes the instrument ideal for continuous dust monitoring.
|
Steam is still one of the most popular methods of providing an energy source to a process and its associated operations. The more accurate and reliable measurements that are made, the more informed decisions can be taken that affect costs and product quality.
|
| In a pulverized coal-fired boiler of a large power plant, an oxygen analyzer is essential for combustion
control. Oxygen analyzers that employ a sampling method may be subject to wear or clogging,
resulting in increased maintenance workload and cost.
|
| Optimum control of ammonia injection is achieved by NOx measurement,
thereby reducing the cost of running such equipment.
The highly sensitive and reliable SG700 stack gas analyzer is most suitable
for the continuous measurement of NOx concentrations.
|
| A package boiler operates more efficiently if the
oxygen concentration in the flue gas is reduced.
Optimizing air intake for boiler operation requires continuous measurement of the oxygen
concentration in the flue gas.
|
Wet flue gas desulfurization or scrubber systems are an excellent way of reducing the sulfur dioxide emissions caused by coal combustion boilers.
|
Level transmitter configuration can be very time consuming.
DPharp transmitters with advanced software functionality
eliminate this time consuming task. With maintenance shops
getting smaller, finding equipment that allows us to do more with
less becomes a priority.
|
One of the most common applications for differential pressure
transmitters is flow measurement. DPharp differential pressure transmitters have some unique signal conditioning features to eliminate instability at low flow rates.
