Adding a much needed 300 MWe at South Africa’s Arnot coal fired power plant
01 December, 2008
As power stations built in the last thirty years approach the end of their design life, and the cost of new capacity continues to increase – along with demands for improved efficiency and lower emissions - an integrated approach to retrofit looks increasingly compelling. The ambitious upgrade project currently underway at the Arnot coal fired plant in South Africa – which will result in an uprate from 6 x 350 MWe to 6 x 400 MWe and a life extension of 20 years – illustrates the benefits.

Large scale steam-solar hybrids take their place in the sun
01 December, 2008
Three solar thermal plants being developed in Spain are among a number of power projects worldwide that illustrate how technology innovation is being applied to the growing demand for cleaner energy. Typically a steam turbine is designed to withstand 1500-2000 duty cycles without requiring significant part replacements or repair. For an application such as those described here the duty is higher by an order of magnitude.

Converting PC to very-high-efficiency IGCC: the MaGIC™ of mild gasification
01 November, 2008
MaGIC™ offers a new approach to “hybrid” coal-fuelled IGCC, combining gasification with combustion. It uses pyrolysis and “mild” (partial) gasification of the char. Using warm gas clean-up, volatiles are preserved in the syngas, doubling its heating value compared with conventional air-blown syngas. MaGIC is much more compact than conventional gasifiers and it is the first IGCC concept that can claim lower capital costs than PC, with significantly lower generating costs. It is retrofittable to existing PC plants (using them as its HRSG), with the potential to dramatically lower CO2 emissions from the existing coal fleet.
