The global market for both industrial and aero-derivative gas turbines is aimed towards increasing efficiency and reducing emissions. Raising efficiency has become imperative to offset the spiralling cost of fuel, with gas price-trends showing no sign of any reduction, while environmental pressures have resulted in ever-tighter regulatory controls on atmospheric emissions, forcing gas turbine manufacturers to focus on the need to reduce NOx emissions in particular to ever-lower levels. Supply utilities and IPPs, together with other end-users are now demanding not only the highest levels of availability and reliability from plant based on gas turbine prime movers, but also the highest possible performance and efficiency. To ensure commercial survival it has become imperative for players at all levels to maximise return on investment in gas turbine-based plant, in terms of higher productivity with the lowest possible costs of operation and ownership over an extended operating life.
