THE FACILITY

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 fiberglass bags.

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.”

 STEWARDSHIP

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.
