Achieving sub-5 ppm NOx with E-class turbines
01 December, 2009
Seventeen GE Frame 6 and 7 GTs in the field have been fitted with the company’s advanced DLN1+ combustion system and now have over 160 000 h of operational experience demonstrating that it reliably meets a 5 ppm NOx standard. That experience is described here.

Capture readiness: CCGT owners needn’t feel left out
01 December, 2009
It looks likely that gas fired combined cycle plants will need to be retrofitted with carbon capture systems in the future, and need to be demonstrating capture readiness now, certainly in the UK. What are the options for raising the steam that is likely to be needed to regenerate the solvent in a post combustion system?

Timely PCM averts second turbine failure at Corus steelworks
01 December, 2009
Swift action to install a condition monitoring system prevented the failure of a second steam turbine at the Corus steelworks in Scunthorpe, UK

A good climate for wind
01 December, 2009
The USA is experiencing unprecedented growth in renewables investment, led by wind power projects, and the leading state is Texas which has nearly 8 GW of wind capacity. In October the world’s largest wind farm was completed when 197 MW was brought on line, bringing the site total to 781 MW.

ZLD operation & maintenance – problems and solutions
01 December, 2009
In Part 1 of this two-part series (see MPS, March 2009, pp 15-19), Dan Sampson, now with WorleyParsons, Sacramento office, discussed the general design options available for zero liquid discharge (ZLD) systems. This second article focuses on the many challenges associated with the operation and maintenance of such systems.

Supercritical-pressure power plants: a progress report
01 December, 2009
Recent trends in steam parameters for supercritical power plants are reviewed, along with the evolution of steam turbine and boiler technology. The current phase of rising main reheat steam temperatures is expected to end early in the next decade, at around 620-630 °C, with new materials making it possible to achieve 28 MPa, 630/650 °C about the middle of the decade and thereafter USC conditions (35 MPa, 700/720 °C) with the promise of efficiencies over 50%.

History in the making at Sihwa Lake
01 December, 2009
Early next year the final touches will be put to its construction and the world’s largest tidal power project, Korea’s Sihwa lake tidal barrage and reclamation scheme, will be ready to come on line. When it starts generating power at its full capacity of 260 MW it will nudge ahead of long term title holder La Rance by a few MW.

Systèmes sans frontières
01 November, 2009
A new organisation has replaced all the former TSO associations in Europe. The European Network of Transmission System Operators for Electricity (ENTSO-E) was brought into existence by the EU in 2008 and started up in July this year. It has a new status, giving it a greater range of duties, which are outlined here.

Going Mainstream – an interview with Eddie O’Connor
01 November, 2009
The first in a series of interviews with the most influential people in the power business as reckoned by the force of their ideas, the size of their office or the spending power they can command. Here Leonard Sanford talks to Dr Eddie O’Connor, founder of Airtricity and Mainstream and creator of the Supergrid concept, a continent-embracing transmission system designed to connect all renewable power sources located at sea.

Cummins engines – planning for the long haul
01 November, 2009
Engine and genset maker Cummins is undertaking a major overhaul of its offerings in readiness for the onset of Tier 4 and Stage 3 legislation due to start taking effect in January 2011. Several of the resulting upgrades have been released this year, and a further tranche of modifications will be applied in 2010.

Utran – India’s most efficient CCGT
01 November, 2009
India’s first GT26-based combined cycle plant is nearing completion in Utran, in the western state of Gujarat. The gas turbine was successfully synchronised to the grid in July and once the plant is fully operational, it will be one of the most efficient power plants in the country. Unusually for a GT26-based plant the facility has a bypass stack to allow simple cycle operation.

A new, integrated, approach to mineralisation-based CCS
01 November, 2009
Mineralisation, ie conversion of CO2 to carbonates, similar to those that occur in nature, is an attractive concept for carbon capture and storage as it can avoid some of the potential public acceptance problems of geosequestering pressurised CO2. But there are major cost and energy penalty concerns. A new integrated approach to mineralisation, avoiding the intermediate step of CO2 extraction and promising considerable benefits, is outlined here.

Clean but flexible: Rotterdam’s Enecogen power plant
01 November, 2009
After five years of planning, and the clearing of several major hurdles, the 870 MWe Enecogen combined cycle facility is now finally under construction. With an expected efficiency over 59% and less than 10 ppm NOx, it will be one of Europe’s cleanest fossil fired plants, but also able to cope with fast cycling operation.
