Exhaust gases from a pulverized coal-fired boiler contain a large quantity of dust. To prevent this from being released into the atmosphere, an electrostatic precipitator (ESP) is used to remove the dust. To maintain the collection efficiency of an ESP and prevent dust emissions, abnormalities must be detected immediately.
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.
Power plant boiler houses designed to burn coal or high sulfur oil are required by Federal and State pollution regulations to "scrub" (remove) sulfur dioxide from flue gasses to meet emission limits. SO2 in flue gasses is known to be harmful to the environment, as it is one contributor to the formation of acid rain. pH control is critical for the proper functioning of the scrubber system.
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.
In flue gas desulfurization systems that use magnesium hydroxide (Mg(OH)2) slurry, the consumption of the desulfurization agent (Mg(OH)2) is controlled by using online pH analyzers. A great concern in the pH measurement is heavy staining of the pH electrodes by the Mg(OH)2 slurry. To ensure accurate measurement, frequent cleaning of the electrodes with an acid is required, adding to both maintenance workload and cost.
Recently, air pollution legislations such as the Clean Air Act to reduce the amount of air pollution are increasing worldwide. The Clean Air Act address numerous air quality problems. One of these problems is acid rain caused by sulfur dioxide and nitrogen oxide emissions from fossil-fueled power plants and other industrial and transportation sources.
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.
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.
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.
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.

The MW100 Data Acquisition Unit comes with many networking functions, including a diverse range of functions for remote monitoring.
Best Solution for Automatic Boiler Control
Sensors and controllers for the efficiency and environmental performance
In a pulverized coal-fired boiler of a large power plant, an oxygen analyzer is essential for combustion control. A pulverized coal-fired boiler is an industrial or utility boiler that generates thermal energy by burning pulverized coal (also known as powdered coal or coal dust).
Industrial Combustion sources such as thermal cracking furnaces and, process heaters play a critical role in the process industry. Because the large amount of fuel such as gas or fuel oil which is consumed in these processes, their combustion efficiency directly affects the performance and operational costs of the production facilities.
The ammonia (NH3) gas is injected to remove the NOx and thus reduce the NOx concentration in the stack flue gas. With conventional NH3 analyzers that perform measurements indirectly, NH3 concentrations are obtained through a sampling system. Therefore, there are problems with the maintenance and running costs of the sampling system, and time delays in measurement. The TDLS200 Laser Analyzer is the solution to all these problems.
STARDOM field control node (FCN) autonomous controllers allow both Modbus master and slave functions to run simultaneously.
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.
Industrial Combustion sources such as thermal cracking furnaces and, process heaters play a critical role in the process industry.
In limestone-gypsum flue gas desulfurization systems, the consumption of a desulfurization agent (lime) is controlled using online pH analyzers.
Floating-point format calculations have enabled physical quantities (in engineering units) to be used in calculations.
