Water injection takes Trent to 58 MW: "the most advanced aeroderivative gas turbine for electrical power generation available today" is how Rolls-Royce sees its Industrial Trent. It was originally intended to be a dry low emissions machine, but recent market pressures have led the company to launch a water injected version, boosting the power from 52 to 58 MW

Modern Power Systems, May, 2004

With a rating of 58 MW the recently launched Wet Low Emissions (WLE) version of the Rolls-Royce Industrial Trent (the Trent 60) is the most powerful of the aeroderivative industrial gas turbines. At 40.7% (60Hz) it is also among the most efficient machines in this size class, although not quite up to the level of the 52 MW e Dry Low Emissions (DLE) version, the Trent 50. At 42%, the Trent 50 can claim to have the highest efficiency among industrial gas turbines of this kind of size.

Developing the DLE version of the Trent, as with other dry systems, has been a long and difficult process, involving a good many iterations to get machines into compliance. The two units at the Avedore multfuel power plant in Denmark will be the last to be...
