COVER FOCUS: COAL TOP PLANTS
A Captive Power Plant's Quest for Reliability
The story of Aditya Power, which serves an aluminum smelter in India, is
one of perseverance and determination. The coal-fired captive power plant's
achievement of operational milestones is remarkable, the result of hard work
and innovative approaches to power generation from first-of-their-kind turbogenerator
sets.
Extensive Planning, Innovative Work Strategies,
Teamwork Combine for Successful SCR Project
The Craig Generating Station in northwest Colorado is an important asset to
its local, rural communities, creating jobs at both the plant and the nearby
mines from which it sources coal. The installation of selective catalytic reduction
(SCR) technology to further reduce the plant's emissions, and keep it operating
efficiently for many more years, has been a successful project, a model of
teamwork and innovation among the plant's owners and contractors.
Dry Fork: A Modern U.S. Coal Power Model
Dry Fork Station in Wyoming offers a template for the modern American coal
plant, with technology enabling efficient power generation that emits few pollutants,
does not discharge water, and reuses its coal ash. It's even become a
proving ground for carbon capture, utilization, and sequestration technologies.
South Korean Plant Finds Flexibility with Advanced CFB Technology 32
The South Korean government wanted to build a coal-fired power plant that
would adhere to environmental standards and be less expensive to operate
and maintain than more conventional coal options. It chose innovative circulating
fluidized bed technology, resulting in the highly efficient Samcheok
Green Power Plant.
Clean Air Program Makes Shawnee Power Plant a Winner
Adding selective catalytic reduction and flue gas desulfurization to two units
at the Shawnee Fossil Plant in Kentucky was necessary to meet regulatory requirements.
Limited workspace made the retrofit a challenge. The Tennessee
Valley Authority came up with innovative solutions to complete the job safely,
while extending the plant's life well into the future.

ON THE COVER
The 2,200-MW coal-fired Samcheok
Green Power Plant in South Korea employs
ultrasupercritical boiler technology
and an innovative circulating fluidized
bed combustion process, making it highly
efficient and fuel-flexible. The plant's
stacks are integrated with-and provide
heat for-the facility's office building and
control room. Courtesy: Sumitomo SHI
