Rolls-Royce Industrial Trent: Combustion and Other Technologies

摘要

In 1993, Rolls-Royce Gas Turbine Engines Canada Inc. (today an integral part of Rolls-Royce Canada) was launched to develop a dry low emissions (DLE) industrial derivative of the aero Trent engine. The aero Trent is now in service powering the Boeing 777 aircraft and the Airbus A330. The Trent 800 is certified at 90,000 lb. thrust and was the first engine in the world to be certified at that level. The industrial version builds on this pedigree and follows a long lineage of aero derivative industrial engines. It has the declared objectives to provide customers with 50MW of power, a life of 25,000 hours for all hot end parts and 50,000 hours on other components, and a thermal efficiency of 42 percent. To build on the experience of the Rolls-Royce RB211- DLE industrial engine, the selected combustor configuration for the 35:1 compression ratio engine was of a cannular design with 3 lean-premix stages in series (primary, secondary, and tertiary stages). The development program for natural gas operation is now at a stage where the main advantages of the 3 stage combustor and other technology features on the Trent can be documented.
