Turbine technology The grid needs more power – fogging can produce it rapidly Fogging – which produces billions of water droplets per second with an average diameter below 10 microns – is a proven cooling technique for application in gas turbine inlet air cooling and wet compression. Both of these technologies could be highly effective in increasing the capacity and efficiency of the existing GT fleet
33 Pressure gain combustion: an efficiency step-change for gas turbines
Finno Exergy’s innovative pressure gain combustion (PGC) concept aims to increase gas turbine efficiency by employing pulsed deflagration. It combines a technology well established in piston engines – pressure rise combustion – with the high power densities and continuous shaft outputs of gas turbines
