COVER FOCUS: COAL TOP PLANTS
Efficiency a Priority at Caofeidian Coal Power Plant
Two ultrasupercritical units added at the Caofeidian power station showcase
a number of innovative efficiency enhancements and incorporate state-of-theart
technology, making them a model for power generators worldwide. The
units are also notable for meeting China's ultra-clean emissions requirements.
Digitization Drives Efficiency at Turkish Coal Plant
A Turkish coal plant has combined start-of-the-art equipment with digital
control and services, and today is recognized as the first and most efficient
ultrasupercritical coal-fired power plant in the country, and one of the best
worldwide.
Success Through Engineered Upgrades and a Focus on Behavior
A power plant in Thailand implemented a far-reaching five-year plan to improve
its coal-handling systems, and in the process became a model for the
entire country. GHECO-One has emerged with a new workforce culture that
includes a proactive mindset for continuous improvement.
Khargone: India's High Efficiency Leap
NTPC, India's power giant, has worked hard to develop advanced technology
to efficiently take advantage of the country's coal resources. The company
commissioned India's first ultrasupercritical unit at the Khargone Super Thermal
Power Station in August 2019, and a second unit at the site in March 2020.
The project marks a key milestone for the country as it strives to develop even
more advanced designs.
Xuzhou 3 Shows the Future of Subcritical Coal Power Is Sublime
While many relatively small subcritical coal units are being retired around
the world, a retrofit on the 320-MW Xuzhou Unit 3 has turned it into a
model of efficiency. In fact, the plant outperforms many supercritical and
some ultrasupercritical units. Furthermore, the project was completed for
less than a third of the cost of building a new unit.

ON THE COVER
An innovative retrofit on Xuzhou 3-a
subcritical coal-fired unit-made it more
efficient than many supercritical and
some ultrasupercritical units. The plant's
steam turbine generator is shown on the
cover. Industry heavyweights Siemens
and GE Power collaborated with the
Chinese team to develop a customized
solution for the machine, which included
higher feedwater temperature, a better
flow path, and higher exhaust steam
quality, resulting in an efficiency improvement
of about 7%. Courtesy: Shanghai
