Metso is again
breaking new ground by introducing advanced power plant applications that
enhance both efficiency and environmental performance.
DNA automation system has now been strengthened to include new control
applications for steam and gas turbines, pulverized coal-fired combustion
optimization, and overall machine condition monitoring. The DNA system is also
pioneering usability applications in process control work.
DNA, you can now have one system for power producers that includes energy
management, plant information management, controls for the boiler, turbine and
Balance of Plant, as well as safety integrated systems and emissions
management," said Edward Coll, regional vice president for Metso Automation
Energy and Process Systems.
Turbine control for steam and gas
The integration of applications for turbine control,
protection and management into the Metso DNA automation system provides
customers with an easy and cost-efficient method to get all turbine
functionality in one common system, Coll said.
Functions included for
turbine control are auto turbine startup, full arc to partial arc transition,
MW control, and several protection features, including over-speed and power
load imbalance. Further, an operator training simulator and turbine performance
monitoring are also available in the integrated DNA package.
level of integration will improve plant responsiveness and lower maintenance
and spare parts costs," Coll said.
Pulverized coal-fired combustion
Metso DNA Pulverized Coal Combustion Manager optimizes
control reactions to dynamic upsets, such as changes in pulverizer
configuration, load demand, or fuel variability, ensuring correct fuel and air
flow into the entire furnace. This optimization of the fuel and air mix
maximizes combustion efficiency while minimizing emissions. Metso further
enhances the reliability of this application by housing it in rugged, and
easily redundant, real-time process controllers, rather than a network-based
Overall, plants using the DNA Coal Combustion Manager consume less
fuel and decrease emissions and emission adsorbents usage, Coll said.
Machine condition monitoring
Another new DNA application
is machine condition monitoring, and Metso is the first to integrate this
function within the process controls. The application provides real-time
condition monitoring of rotating machines, such as fans, pumps and turbines,
and it allows the operator to see condition monitoring alarms in the same
interface with process alarms. Condition monitoring has traditionally been a
separate system, mostly utilized by maintenance specialists. Now, with the
Metso DNA Machine Monitoring application, both monitoring and process alarms
can be shared with operators in the control room. This "advance warning system"
reduces the likelihood of unscheduled outages and improves maintenance
efficiency by alerting operators to potential problem areas before a breakdown
The Metso DNA
Sootblowing Manager calculates, stores and displays boiler heat transfer
characteristics that indicate fouling and deposit accumulation on heat transfer
surfaces. It also defines the economically optimal sootblowing sequence and
location. By optimizing the sootblowing process, a plant can improve efficiency
by lowering soot losses, and also improve reliability by reducing unnecessary
Enhancing usability by increasing operator
knowledge and control
Metso is also pioneering "usability" in
process control work, providing operational information in both real time and
retrospectively, which allows system operators to have much greater insight
into processes over time which, in turn, enhances their control.
"Despite being fact-based by its nature, process control work at power
plants also includes a lot of interpretation and real-time problem-solving,"
said Jaakko Oksanen product manager for the Metso DNA automation business line.
"When all the aspects of business and production processes are visible and
under control, stress is reduced, and people make better decisions because they
are in control of their work. It's the perfect combination of artificial and
human intelligence coming together to solve problems."
An example of
usability: Metso DNA is the only system in the world from which the user
receives process data in real time and retrospectively, from the same user
interface, using the same graphic displays, with one push of a button.
"The user can easily access all the data collected during his or her
absence, for example, over the weekend," Oksanen said. "Traditionally, the
history of this information required separate applications, and data analysis
was difficult. Here, we have taken usability into consideration to enhance
operator control and create a more knowledgeable, positive user experience."
Lower operating costs based on Metso life cycle support
Metso DNA is supported by a global network of local experts who provide
customer service on-site and through remote connectivity. In addition to
product support, the portfolio of Metso services includes training, process
improvement services and assured upgrade capability. The single system
architecture of Metso DNA enables lifelong compatibility and upgrading options.
As a result, Metso customers have confidence that their investment will pay
dividends for the long-term because the system provides step-by-step upgrade
paths that facilitate future system improvements according to changing process
and functionality needs.
One system for all
DNA system enables power plants to integrate all operations into a single
plant-wide, or even corporate-wide entity, enabling easy access to information
for comparing and combining process data. Operators only need to know one
system, and customers also benefit from having a single source for global
system support, updates and spare parts. The result is a power plant that has
lower fuel costs, reduced emissions and higher availability.
