Efficient boiler operation requires boiler auxiliary equipment to operate in harmony. The air preheater, for example, though it has few moving parts, is vital to maintaining efficient boiler performance. In this second installment of our Power 101 series, we examine performance degradation caused by corrosion and fouling of the air preheater that results from the combustion of coal plus the effects of ammonia and sodium bisulfite injection for SO₃ mitigation.

Westinghouse’s AP1000 reactor design hit several milestones in recent months, prompting speculation that it could take the coveted lead in the charge to deploy the world’s third-generation nuclear power plants.

HD Electric Co.’s new PRX-500 Proximity Voltage Detector is an addition to its voltage detector product line. With nine selectable voltage ranges from 120 V to 500 kV, the PRX Proximity Voltage Detector features an easy-to-use electronic touch pad with large buttons. The PRX provides an audible and visual indication of voltage detected from elbow […]

San Miguel Electric Cooperative selected and installed an automatic sootblowing system for its Unit 1 to minimize clinkers in the boiler that caused semi-annual unscheduled outages. New boiler surface-cleaning equipment and intelligent cleaning software eliminated these expensive outages.

U.S. Interior Secretary Ken Salazar in late December approved—for the ninth time since October 2010—a solar power project to be built on federal lands.

John Deere Power Systems (JDPS) introduced extended generator drive emergency stationary power ratings for its PowerTech E 6.8L diesel engine—the first John Deere engine to carry both U.S. Environmental Protection Agency Tier 3 Emergency Stationary and European Union Stage III A certification, with dual frequency ratings of 1,800 and 1,500 rpm. The 212-kW rating at […]

President Obama’s Jan. 25th State of the Union address proposed that the nation commit itself to developing "clean energy" sources of electricity over the next two decades. A critical assessment of his proposal finds that it’s just a rehash of previously rejected legislative proposals. In fact, to me, it sounds like Waxman-Markey all over again. I have a better idea.

Lao People’s Democratic Republic (PDR), the tiny landlocked country in Southeast Asia of just 6.3 million people, in December inaugurated the 1,070-MW Nam Theun 2 Power Station, a hydropower project in Khammouane Province.

Spirax Sarco launched the TD120M Thermo-dynamic Steam Trap, a product engineered for pressure ratings of up to 3,190 psig that is ideal for draining saturated and superheated steam mains. The steam trap has a maintainable disc and seat, which means it can be serviced in-line—a considerable benefit to customers with welded installations. The trap has […]

Duke Energy and Progress Energy announced January 10 that they are combining to create the nation’s biggest electric utility. The $13.7 billion deal is likely to draw tough scrutiny from federal and state regulators—and some protests from big power buyers—given the companies’ overwhelming market dominance in North Carolina and more modest operational overlap in South Carolina.
