State-of-the-art gas turbines--a brief update

Power market forecasts are confirming a strong upsurge of interest in gas turbines and combined cycle power plants. The trend is being driven by a range of benefits that include lower investment and power generation costs, shorter plant construction times, high availability and low emissions. Gas turbine development work in recent decades has created a platform that will enable manufacturers to meet the more rigorous demands being made on these machines. With the GT24 and GT26, ABB has both an innovative concept and the core technologies that will make it possible, in the near future, for combined cycle plants to achieve 60% thermal efficiency while complying with tough emission standards.
