Power Engineering

Features
- 2012 Outlook for Fossil Power
  When it comes to natural gas-fired and coal-fired assets in North America, two subjects have taken over the headlines: The amount of natural gas available for electricity production in North America and regulations from the U.S. Environmental Protection Agency that are pending and have been passed.
- Renewable Energy Executive Roundtable
  Renewable energy in the U.S. is at a crossroads.
- Best of the Year
  At a gala banquet at POWER-GEN International in Las Vegas, Nev., on December 12, Power Engineering magazine's editors recognized the 2011 Projects of the Year Award finalists and announced three winners.
- Large Aero-Derivative Gas Turbines for Power Generation
  The decision to use aero-derivative gas turbines is mainly based on economical and operational advantages.
- Mercury Control Options to meet MATS
  Mercury control for coal-fired power plants is not a "one size fits all" technology.
- Investigating the Effects of Piping Configuration and Water Supply Pressure on Air Intrusion
  A study to understand the effects of geometry and water supply pressure on the void transport has been performed using RELAP5.

- Feedback
  - To the Editor:
    The Bonneville Power Administration (BPA) has connected so much new wind generation to its transmission system so fast that the BPA grid now holds more wind capacity than all but three states.
- Opinion
  - New Year, New Rules, New Challenges
    For U.S. power generators, 2012 should be a momentous and decisive year.
- Clearing the Air
  - Changing Attitudes at the EPA
    Although I'm sure not much sympathy can be found in this audience, 2011 was a difficult year for the Environmental Protection Agency.
- Gas Generation
  - Natural Gas Spark Ignition Engines…what, why, when, and where?
    The reciprocating internal combustion engine is a well proven and familiar technology with decades of use for stationary power generation.
- View on Renewables
  - Adapting to the Changing Times
    Two years ago, the U.S. pledged to reduce its greenhouse gas emissions 17 percent below its 2005 levels by 2020.

  - U.C. Davis Beats Emissions Requirements While Boosting Steam Output
    Starting out as the University Farm in 1905, UC Davis has become a research leader in biology, agriculture and environmental science.
- What Works
  - Combining Ultrafiltration and Reverse Osmosis Technologies Key to Producing Pure Water for Power Plant Boilers
    As power plant designs have evolved over the past 50 years, top boiler pressure i.e. superheated high pressure turbine inlet conditions, has increased dramatically.
- Products
  - Data acquisition and analysis software
    Kistler, a supplier of precision sensors, systems and instrumentation for the dynamic measurement of pressure, force, torque and acceleration, has introduced the USB-based Type 2825A DynoWare universal data acquisition and analysis software, designed for direct compatibility with Kistler stationary and rotary measuring systems, including single- and multi-component dynamometers and other force sensors.
