New Gas-Fired Plants Come Online in Michigan

Upper Michigan Energy Resources Corp. (UMERC) placed two new natural gas-fired generating stations into commercial operation on March 31, part of the company’s plan to reshape its generation fleet as it seeks to “balance reliability and customer cost with environmental stewardship.” UMERC, a subsidiary of WEC Energy Group, also retired the coal-fired 430-MW Presque Isle […]

The Importance of RTO Maintenance

The importance of RTO maintenance
RTOs or Regenerative Thermal Oxidizers control emissions without producing harmful byproducts or hazardous waste. They help destroy volatile organic compounds (VOCs), hazardous air pollutants (HAPs) and other odorous emissions created during normal manufacturing and industrial processes by combusting them into carbon dioxide and water. RTOs pass hot exhaust gas and cooler

Inside NET Power: Gas Power Goes Supercritical 

A project to demonstrate a novel power cycle that promises to produce low-cost, reliable, and flexible power from natural gas—while generating no atmospheric emissions, and fully capturing carbon dioxide—is inching closer to commissioning. Its developers are now actively assessing siting for the first commercial-scale 300-MW NET Power facility. NET Power’s 50 MWth Demonstration Plant in La […]

What Are Supercritical CO2 Power Cycles?

While conventional power plant cycles produce power from turbines using water or steam as the working fluid, supercritical carbon dioxide (sCO2) cycles use CO2 that is in a supercritical state—at a temperature and pressure above its critical point where liquid and gas phases are not distinguishable.  CO2 has a relatively low critical pressure of 7.4 megapascal […]

The Economic Thicket of Generating Cost Comparisons

Comparing the costs of differing electric generating technologies has become popular among advocates for particular technologies and those seeking to find the optimal approach to new generation. While getting

Plenty of Natural Gas to Go Around—It Just Needs a Market

Demand growth for natural gas for power generation may have slowed in the U.S., as renewable resources continue to take market share. With U.S. production continuing to hit record highs, and new gas-fired

Controlling Boiler Level When Operating Conditions Change

The right level instrumentation is key to keeping boilers on an even keel. Guided-wave radar offers a critical combination of capabilities. If asked to make a short list of factors able to improve heat rate

Managing Thermal Quench Damage at Power Plants

Attemperation equipment is necessary to control steam temperatures at many power plants. However, when the equipment functions improperly or the design is flawed, thermal quenching/shock can damage piping
