Rethink wind strategy, Carbon Trust tells UK government
The UK will build only a quarter of the 29 GW of offshore wind farms needed to reach its target to have 15% of energy from renewable sources by 2020 unless the government acts urgently to reduce costs and risks to developers, a government-funded but independent think tank said in a report launched last week.

Expect big-time spending in a new administration
By Kennedy Maize What will the new president really do once on infrastructure spending, despite the anodyne economic platitudes of the campaign? My guess is we will see the greatest economic stimulus effort since WW2. Deficits be damned. That’s probably good. The economic enemy is deflation, not inflation, if the Great Depression is any […]

Bringing down the cost of SO2 and NOx removal
A twist on an old technique, flue gas recirculation, helps prevent slagging in the upper furnace and convective pass, according to pilot testing recently completed by APTECH CST and the Southern Research Institute. The technology—along with a companion technology for furnace sorbent and urea injection for SO2 and NOx control—could help owner/operators of smaller, older coal-fired plants meet emissions limits at a reasonable cost.

Managing software life-cycle issues
Software ranges from shrink-wrapped products available “off the shelf” to custom corporate implementations of enterprise systems that require sessions with shrinks to keep everyone sane. Regardless of its complexity, every piece of software a plant uses, or interfaces to, poses critical issues that require life-cycle management. Although functionality has always been the chief specification for software, plants must pay far more attention to long-term quality issues. These two concerns are often at odds with each other.

Finessing fuel fineness
Most of today’s operating coal plants began service at least a generation ago and were designed to burn eastern bituminous coal. A switch to Powder River Basin coal can stress those plants’ boiler systems, especially the pulverizers, beyond their design limits and cause no end of operational and maintenance problems. Many of those problems are caused by failing to maintain good fuel fineness when increasing fuel throughput.

An increasing number of low-pressure steam turbines—especially at supercritical fossil units—have experienced stress corrosion cracking in the blade attachment region of their low-pressure rotors. Approaches to solving this problem range from redesign of the attachment and blade replacement to in-situ weld repair. Regardless of the procedure selected, the solution must completely restore the turbine performance while minimizing outage duration.

TS Power Plant, Eureka County, Nevada
Top Plant: Not all coal-fired power plants are constructed by investor-owned utilities or independent power producers selling to wholesale markets. When Newmont Mining Corp. recognized that local power supplies were inadequate and too expensive to meet long-term electricity needs for its major gold- and copper-mining operations in northern Nevada, it built its own generation. What’s more, Newmont’s privately owned 200-MW net coal-fired plant features power plant technologies that will surely become industry standards. Newmont’s investment in power and technology is also golden: The capital cost will be paid back in about eight years.
