Background burner control is critical for power and industrial plants because it affects emissions, energy costs, and process efficiencies. For natural gas burners, variations in gas composition can have a

An email written by the team leader of an ongoing Nuclear Regulatory Commission (NRC) inspection being conducted at the Pilgrim nuclear power plant suggested that the facility’s staff were “overwhelmed by just trying to run the station.” The wide-ranging NRC inspection began on Nov. 28. It is the third and largest inspection conducted as part […]

Increasing plant efficiency and reducing maintenance costs is important for economic power plant operation. One part of the task involves keeping the boiler heating surfaces as clean as possible, which increases heat transfer, reduces maintenance, and avoids unplanned standstills of the plant. Shock pulse generators (SPGs) are an innovative and efficient way to manage boiler […]

Many coal power stations have recently been operating at historically low capacity factors or have even undergone extended economic shutdowns. This can result in coal stockpiles that are exposed to the elements for much longer times than anticipated, resulting in a loss of usable coal energy by several mechanisms. This article explores the severity of […]

The International Association for the Properties of Water and Steam (IAPWS) is an international nonprofit association of national organizations concerned with the properties of water and steam, particularly

Owner/operator: Exelon Generation and PSEG Nuclear/Exelon Generation When decision-makers choose to increase the maximum output of a nuclear power plant through an uprate, it sets in motion a process that can take many years and countless man-hours to complete. The success of Peach Bottom station’s extended power uprate project shows that all the long hours […]

To power generation professionals, the word “cavitation” typically has negative connotations, but a new process offers a way to control this normally destructive effect and deploy it as a cost-effective life-extension technique. As operators of commercial nuclear energy facilities consider subsequent license renewals and life extensions, finding new ways to safely maintain reactor components remains […]

The world’s first wind farms are reaching the end of their expected lifetimes. As they become outdated, or just inefficient, many developers are considering repowering. Here’s a look at where repowering activity is happening the most and why. Since the world’s first wind turbine used to convert wind energy into electricity was built by Professor […]

A magnetic level gage may be an excellent addition to a power plant boiler’s drum-level instrumentation. However, before any changes are made, owners must first understand the specific minimum requirements for water level instrumentation defined by the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code. The code requires a functional water gage […]

Security is taken very seriously at most power plants. Fences and other barriers are usually installed before construction of a plant even begins to keep curious busy-bodies, thieves, protestors, and—at the far end of the spectrum—saboteurs and terrorists out of sensitive locations. Some plants have dedicated security staff patrolling areas both inside and outside of […]
