In the late 1980s, the U.S. Department of Energy (DOE), in conjunction with industry and state agencies, started the Clean Coal Technology (CCT) program. The aim of the CCT program was to develop technologies, increase efficiency, and reduce the environmental effects of burning coal in power plants. Today, pollution controls for new and existing plants […]
History has shown that the proper deployment of automation on new construction projects can make the difference between a moderate performer and an industry-leading unit, between average financial results and accelerated profitability. Given the magnitude of a new coal-fired plant construction project, automation is often viewed as just one of the many components essential to […]
The Mission of the National Coal Transportation Association (NCTA) is to provide education and facilitation for the resolution of coal transportation issues in order to serve the needs of the general public, industry, and all modes of transportation. This is accomplished through the sponsoring of educational forums and by providing opportunities for the lawful exchange […]
The first power plants were built about 130 years ago. Coal was then, and is still today, the major fuel used for power generation. Currently, about 1,400 pulverized coal – fired units, with an average age of more than 30 years, generate over 50% of U.S. electric power. The use of low-sulfur coal and improved […]
Understanding why stack emissions become opaque leads to better choices of systems for controlling SO3 and other pollutants, based on current and future plant operating configurations.
With the 2006 hurricane season about to begin, climatologists are predicting that the Atlantic Ocean will spawn 17 “named” storms this summer and fall, with 9 categorized as hurricanes and 5 expected to be “intense.” Whether or not your plant lies in a vulnerable coastal area, you’d do well to learn a few lessons from Entergy’s unique experience last year.
If engineered well and drained properly, a simple finned-tube heat exchanger can help maximize a fossil-fueled power plant’s combustion efficiency, capacity, and air pollution reduction. Use the guidelines in this article either to return a disabled steam coil air preheater to service or to improve the performance of a unit that may have been wasting […]
Primary airflow has a major impact on the efficiency, capacity, and cleanliness of pulverized coal–fired generation. Inaccurate measurements that underestimate primary airflow levels can lead to negative operational outcomes that include increased boiler gas temperatures, flyash loss-on-ignition, excessive NOx emissions, and higher-than-necessary fan power consumption. We remind you how to avoid those headaches.
T/P92 is being heralded as a superior and lower-cost alternative to T/P91 for new power plants with pressures above 3,600 psi and temperatures above 1,100F—such as the supercritical and ultra-supercritical units proposed to be built in the U.S. over the next few years. The switch from T/P91 to T/P92 would represent the next step in […]
The California Energy Commission (CEC) recently awarded about $14 million for carbon sequestration projects to be overseen by the West Coast Regional Carbon Sequestration Partnership. Westcarb, as the partnership is known, is part of the U.S. DOE’s effort to deploy technologies through its Regional Carbon Sequestration Partnership (RCSP) program. New members Alberta and British Columbia […]
