HRSG advances keep GTCC competititve
23 August, 2004
Gas fired combined cycle power plants mothballed after the initial dash for gas are tending to be recommissioned again now that the increase in open market electricity prices appears to be a dependable trend. New combined cycle plants entering the market will need improved flexibility and durability during load cycling operations as well as further increases in thermal efficiency to be financially bankable. Recent important advances in HRSG design may be the key to viability on this front.

Dynamic classifiers: a fine way to help achieve lower emissions
08 April, 2004
There have been very few conversions of UK coal mills from static to dynamic classifiers. But test experience with a dynamic classifier at Powergen's Ratcliffe-on-Soar power station has demonstrated significant fineness gain, especially at the coarse end of the particle size distribution curve, and minimal effect on mill coal throughput and operability, with greatly reduced in vibration levels. All mills at unit 1 are to be converted. The increased fineness will help offset the lower combustion efficiency (as measured by unburnt carbon levels) to be expected when a boosted overfire air system is fitted to the plant to reduce NOx.

H System steams on
21 February, 2004
Commercial operation of the first 50 Hz plant to employ GE's H System technology – with its innovative closed-loop steam cooling – was followed by the announcement of a site for the all-important 60 Hz lead project, now the subject of a study to determine whether it is the best way of meeting Québec’s energy needs.
