A new analysis of 85 hydroelectric reservoirs distributed around the world suggests that these systems emit about 48 million metric tons of carbon annually. That figure is much lower than earlier estimates of 64 million metric tons that were based on studies relying on more limited data and which cautioned that reservoirs of all types […]

Siemens Gets $1 Billion Order to Build Gas Power Plants in Thailand. Siemens on Aug. 17 said it received two orders worth $1 billion from Thailand for the engineering, procurement, and construction (EPC) of combined cycle power plants. The firm will build Chana Block 2 in the province of Songkhla and Wang Noi Block 4 […]

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 plummeting cost of photovoltaic (PV) panels—resulting from lower costs for high-grade silicon and advancements in thin-film technology, solar storage, and electronic control technologies—has a slew of firms rethinking concentrating solar power (CSP) projects. Although there is a CSP project pipeline (including both CSP and concentrating PV) of more than 9 GW in the U.S., […]

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.

America’s energy and environmental policies have been dysfunctional for decades. Obsessively moving toward “green” has made America weaker and has damaged our economy. During POWER’ s first 100 years (1882–1982), the magazine chronicled the U.S. growing into the strongest industrialized economy in the world. America designed and built products for the world using raw materials and energy from within our own borders. Now we are in a recession and the U.S. Environmental Protection Agency’s (EPA) “War on Coal” continues. Does anyone get the connection? Ever-worsening regulations are killing jobs by the thousands.

Global Training Solutions Inc. released an interactive, self-paced, and fully customizable electronic training program to achieve compliance with the North American Electric Reliability Corp.’s (NERC’s) Critical Infrastructure Protection (CIP) security standards. The company designed its NERC CIP Information Security E-Learning Series on open-web standards, sharable content object reference model (SCORM) compliance, and advanced technical concepts. […]

The range of the NLB 605 Series has been expanded to include eight operating pressures from 4,000 psi […]

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 […]

One of the world’s first breakwater wave power stations was commissioned this July by Ente Vasco de Energia (EVE), an energy agency in the northern Basque region of Spain. The €2.3 million ($3.3 million) project in Mutriku uses oscillating water column technology developed by Voith Hydro’s Wavegen, based in Inverness, Scotland. The technology is integrated into a concrete power station built on a breakwater or coastal protection project.
