JEA’s Northside Generating Station in Jacksonville, Fla., Units 1 and 2 were built in 1966 and 1972, respectively, although the Unit 2 boiler had not operated since 1983. Both were heavy oil– and natural gas–fired steam units rated at about 300 MW. The utility “repowered” those two units by removing the old boilers and adding new circulating fluidized bed (CFB) boilers (Figure 1) that entered service in 2002. At that time, they were the world’s two largest CFBs, and the plant won POWER’ s Plant of the Year Award.

The new NLB 605 series of water jet pump units from NLB Corp. gives users a powerful combination of ultra-high pressure and high horsepower in a rugged unit they can convert to a variety of operating pressures. The range of the NLB 605 Series has been expanded to include eight operating pressures from 4,000 psi […]

Acoustic pulse reflectometry (APR) is a tube inspection method that has been gradually gaining acceptance as a tool for heat exchanger inspection. Different types of heat exchangers operating in different operating environments have different failure mechanisms, making some of them more suited than others for inspection by APR. Finned tube heat exchangers are a typical example of heat exchangers particularly conducive to APR inspection.

The BelGAS division of Marsh Bellofram Corp. introduced Type P627, a high-performance, spring-loaded, direct-operating high-flow gas regulator that is designed to control both low- and high-output pressure in oil and gas applications. Designed for maximum durability, Marsh Bellofram BelGAS Type P627 regulators are compact and offered in multi-position body and spring case configurations. Units offer […]

As last winter’s abundant snowfall in the Pacific Northwest melted, rivers swelled and hydroelectric operators enjoyed substantial increases in generation. That bountiful clean and cheap power generation was a blessing, but it also triggered a host of legal issues.

BeamCap’s signature product, the BeamCap, prevents dust accumulation on I-beams, structural steel members, pipes, cable trays, and other difficult-to-clean areas. BeamCap pieces completely enclose the structures, eliminating horizontal surfaces where dust consistently builds up. This eliminates the need for cleaning in hard-to-reach places and greatly reduces the potential for fires and secondary explosions. The aluminum […]

Situated in predominantly rural central Illinois, the 1,000-MW Coffeen Energy Center has installed a number of controls in recent years and achieved significant environmental performance. For example, in 2010 a new scrubber facility was added that reduces SO₂ from combustion gases coming from the plant’s two coal-fired boilers. The plant personnel’s continuing commitment to protecting the environment helps to promote a strong relationship between the plant and the local community.

Aqua-Vu, a provider of portable underwater viewing systems, introduced the Claw 360, a device designed for the detection and removal of objects in an underwater environment. The Claw 360 incorporates a Sharp 520 color camera that can rotate 360 degrees to scan the environment. Lighting is provided by high-intensity LEDs that rotate with the camera. […]

CPS Energy, the largest municipally owned utility in the U.S. providing both natural gas and electric service, implemented an energy plan in 2003 that required energy conservation measures, use of available renewable energy sources such as wind and solar, and additional coal-fired generation. The $1 billion 750-MW Spruce 2 fits into that plan by being one of the cleanest coal-fired plants in the country.

Advance Products & Systems’ new Kleerband Flange Protectors and Radolid Protection caps protect bolts, nuts, and flange faces on raised-face or full-face flanges in conditions where extreme corrosion occurs, such as at gas plants, pump stations, and above- and below- ground installations. Kleerband is a patented transparent polymer band with grease injection fittings and a […]
