Plant Design

Electrical cable and conduit offers a reliable and proven way to get power where it needs to go, but that doesn’t mean it is always the best method. Busway can save space, while offering a less-expensive, more-flexible power distribution solution for applications where change and adaptation are important. As is the case in many other […]

Plant wastewater treatment is not what it once was, and changes in the Environmental Protection Agency’s effluent limitations guidelines (ELG) have added a host of new wrinkles. A panel of power plant experts discussed what plant managers are planning and doing to keep things running smoothly within the new rules. For more than three decades, […]

Fortum Värme, a company jointly owned by Finnish energy firm Fortum and the city of Stockholm on May 9 inaugurated a new biomass-fired combined heat and power (CHP) plant on the shores of Värtan, a strait in Sweden’s capital city. The Värtan CHP8 (130 MWe, 280 MWth), which began construction in 2013, will begin commercial […]

Fuel cells are a rapidly expanding option for distributed generation, with fuel cell–based power plants now being deployed in capacities into tens of megawatts (see “59-MW Fuel Cell Park Opening Heralds

China’s CAP1400—a reactor design based on Westinghouse’s AP1000 pressurized water reactor—has successfully passed the International Atomic Energy Agency’s (IAEA’s) Generic Reactor Safety Review. The milestone is significant for China, which plans to deploy the advanced reactor design in large numbers (Figure 4) as well as export the technology. 4. On the nuclear horizon. An artist’s […]

When gas-fired plants are required to cycle more than they were designed for, added stress on plant components isn’t the only consequence. You also need to pay closer attention to turbine catalyst systems. Traditionally, many combined cycle gas turbine (CCGT) power plant units were designed and permitted for a baseload or similar operating profile. Startups […]

When owners of the Big Stone Plant researched air quality control system technology, they considered all available options and eventually settled on a design that was not in widespread use. Now that the

Is waste-to-energy the best greenhouse gas fighter among electric generating technologies? Or do trash burners spew dangerous air emissions? The answer may be a surprise. What electricity-generating technology results in net greenhouse gas (GHG) reductions, not just zero new emissions? According to the U.S. Environmental Protection Agency (EPA), it’s not nuclear, not wind, not solar. […]

Although it’s not widely publicized, a majority of the energy used to generate electricity is wasted in the form of heat discharged to the environment. For better or worse, that’s just the way a typical thermal power plant works. Fuel, such as coal, biomass, natural gas, or uranium (in the case of nuclear plants), is […]

The nuclear industry has been expecting big things from small modular reactors (SMRs) for a long time, but to date, no SMRs have reached commercial construction phase. That may change soon. Utah Associated Municipal Power Systems has a plan to deploy NuScale Power’s Integral Pressurized Water Reactor at a site in Idaho. Will others follow […]
