The Logan Generating Plant, located on the Delaware River in Logan
Township, New Jersey, is a 225 megawatt cogeneration facility. Fueled
by pulverized coal, the plant provides 203 megawatts of electricity
— enough for approximately 203,000 homes — to Atlantic
City Electric. It also supplies steam (up to 50,000 pounds per hour)
to a nearby Ferro Corp. facility. Uncommitted capacity and energy
beyond the Atlantic City Electric requirements are sold into the
regional wholesale market.
TECHNOLOGY AND ENVIRONMENTAL PERFORMANCE
With advanced environmental control technologies, Logan is one
of the cleanest coal-fueled electric generating plants in the world.
Emissions levels are well within federal and state requirements.
Logan was among the first commercial scale pulverized coal plants
in the United States to use selective catalytic reduction (SCR)
technology, and the first to use a plate-type catalyst to reduce
emissions of nitrogen oxides (NOx). The SCR system injects an ammonia
vapor into the flue gas in the presence of a special catalyst, which
causes the nitrogen oxides to separate into simple elemental nitrogen
and water vapor, or steam. Working in concert with low-NOx burners
and an advanced overfire air system, the system cuts NOx levels
dramatically, allowing the plant to operate very cleanly. In fact,
the plant's nitrogen oxides emissions are among the lowest of any
solid-fuel plant in the Mid-Atlantic region.
Scrubber and filtering systems remove sulfur dioxide and particulate
matter, respectively. In particular, the spray dryer absorption
(SDA) system is designed to remove 93 percent of the sulfur dioxide
(SO2) emissions. The SDA system feeds a mixture of lime and water
into an atomizer that reduces the liquid to a very fine spray. The
mist-like spray mixes with incoming flue gases, capturing the sulfur
and forming a dry powder. The powder is then removed in the dust
collection system. Some of the dust may then be recirculated to
reduce the plant's lime consumption. Finally, more than 99.9 percent
of the remaining dust is captured in a 12 compartment filter, known
as the baghouse, which is lined with more than 4,000 Teflon®-coated
Logan also features an advanced zero-discharge water treatment
system designed to reduce its water intake from the Delaware River
by nearly 40 percent and to eliminate any discharge of process wastewater.
A sophisticated, enclosed conveyor system with a unique environmental
design transports the coal from the barge and along the plant's
pier to the coal handling building without any releases of coal
dust to the air or water.
In 1995, the publishers of Power Engineering and Power Engineering
International selected the Logan Generating Plant as one of three
“Projects of the Year.” The plant was honored for its
“excellence in design, construction and operation.”
The plant extends this excellence to a number of philanthropic
and educational programs, supporting such organizations as the Rowan
College Fund, the United Way, the Make A Wish Foundation, Logan
Township public schools, the Youth League and the volunteer fire
department. Logan Generating is a regular participant and supporter
of the local elementary school science fair and routinely opens
its doors for students and their parents to tour the facility. The
plant has also been a regular sponsor of the South Jersey Summer
Institute for Educators, whose goal is to give teachers a firsthand
look at the key issues and challenges facing the business community,
allowing teachers to take business education back to the classroom.
