Gas turbine WR-21

for marine applicationsaeroderivative

The WR-21 is the first production aero-derivative gas turbine to incorporate compressor inter-cooling and exhaust heat recuperation technologies that deliver low specific fuel consumption across the engines entire operating range. The 25MW WR-21 has a footprint is no larger than current simple cycle marine gas turbines and offers a 25-27 per cent fuel saving. Reliable components from current Rolls-Royce RB211 and Trent engines are at the core of the truly modular WR-21, designed for ease of maintenance and reduced through life costs. The gas generator and power turbine consists of 12 interchangeable pre-balanced modules. Because of their size and low weight, these modules can be removed and new modules can be fitted to reduce maintenance costs and down time.
