The combined cycle power plant is being installed in increasing numbers around the world where there are substantial supplies of natural gas. Yokogawa’s power experts deliver total instrumentation and control solutions.
Improving power plant efficiency
Yokogawa helps power plants operate more efficiently by improving the control of fuel, steam, and feed water.
CENTUM VP Integrated Production Control System
The CENTUM VP integrated control system secures interruption-free “uptime only” plant performance for optimal productivity and profitability in the renewable energy field.
Transmitter
The DPharp series of digital pressure transmitters use a differential pressure high accuracy resonance pressure (DPharp) sensor that represents one of the most revolutionary advances in transmitter technology.
Zirconia Oxygen Analyzers
Yokogawa’s zirconia oxygen analyzers are used for combustion monitoring and control applications and are relied on by a wide range of industries to optimize combustion and reduce NOX emissions.

Improving combustion efficiency and reducing/eliminating harmful stack emissions
Yokogawa oxygen analyzers measure the oxygen (O2) concentration in flue gas. With this information, the air-fuel ratio can be adjusted to optimize combustion. Likewise, our stack gas analyzers can be used to reduce harmful emissions by measuring the concentrations of nitrogen oxide (NOX) and sulfur oxide (SOX) in stack gas.
ZR Series Zirconia Oxygen Analyzers
Yokogawa’s zirconia oxygen analyzers are used for combustion monitoring and control applications and are relied on by a wide range of industries to optimize combustion and reduce NOX emissions.
SG Stack Gas Analyzer
The SG stack gas analyzer consists of an infrared gas analyzer unit, a zirconia oxygen analyzer unit, and a sampling unit, and can simultaneously measure up to five components: NOX, SO2, CO2, CO, and O2.
Reducing the emission of CO, NOX, dioxins, and other substances into the atmosphere by burning off residual gas components in the stack gas
Yokogawa gas analyzers measure the oxygen concentration in the stack gas so that adjustments can be made in the O2 supply that will improve combustion efficiency and burn off more residual gas components.
CENTUM VP Integrated Production Control System
The CENTUM VP integrated control system secures interruption-free “uptime only” plant performance for optimal productivity and profitability in the renewable energy field.
ZR Series Zirconia Oxygen Analyzers
Yokogawa’s zirconia oxygen analyzers are used for combustion monitoring and control applications and are relied on by a wide range of industries to optimize combustion and reduce NOX emissions.
TDLS Laser Gas Analyzer
The TruePeak TDLS gas analyzer relies on a proprietary peak area integration method and is ideal for in-situ analysis in harsh process environments. It significantly improves the efficiency of boiler operations.
SG Stack Gas Analyzer
The SG stack gas analyzer consists of an infrared gas analyzer unit, a zirconia oxygen analyzer unit, and a sampling unit, and can simultaneously measure up to five components: NOX, SO2, CO2, CO, and O2.
Prevent fire accident in coal yard, transmission, and any other facilities.
Distributed Temperature Sensor (DTS) provided by Yokogawa contributes fire detection, Leak/Plugging Detection, Hot (Cold) Spot Monitoring, and Facilities Preventive Maintenance.
Distributed Temperature Sensor (DTS)
Yokogawa DTSX makes possible gapless detection and monitoring up to 50km.
Combined cycle power generation requires the following control and optimization.
Unit control: boiler/ burner management/ turbine/ balance of plant/ flue gas desulfurization/ emergency shutdown
Plant optimization: plant information management/ operation efficiency improvement support/ alarm management
Sandi Electricity Company selected Yokogawa to replace Foxboro IA Series at its power plant.
Yokogawa carefully extracted the configuration of old systems and successfully replaced with CENTUM VP and ProSafe-RS.
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. (AN10D01P01-01E)
Cogeneration systems that improve overall energy utilization by simultaneously generating electricity and heat from a single fuel source have been in the news a lot recently. Distributed generation equipment, a type of cogeneration system, is driven by a gas or diesel engine. Advantages of the gas engine, which is widely used, include high thermal efficiency and secure fuel supply.
