Rolls-Royce Turbine Powers Past Milestone - Trent 60 turbine-generator package passes 50 000 hours of operation

摘要

The first ever application of the Rolls-Royce Industrial Trent 60 gas turbine has recently reached a performance landmark in the small town of Whitby on the north shore of Lake Ontario in Canada. The unit, a Trent 60 turbine-generator package, entered commercial service in 1988 with Whitby Cogeneration. A major milestone was recently achieved when the package completed 50 000 hours of operation, generating power for the Ontario power grid while providing steam in the cogen mode to the adjacent Atlantic Packaging site - the steam host Although the 50 000-hour milestone is far from being spectacular in terms of power generation, the figure is a memorable and welcome achievement for the developers behind the project who had to overcome several challenges associated with introducing the unit into service. The natural gas-fired, aero-derived Trent 60 is capable of delivering up to 58 MW in simple-cycle operation. Whitby has a guaranteed performance rating of 51.2 MW and 40.3% efficiency at its ambient design reference point of 7.8℃ At ambient temperatures below -6.7℃, the Whitby unit generates 57.7 MW in simple cycle The cogeneration plant utilizes a single pressure once through steam generator (OTSG) supplied by Innovative Steam Technologies (IST) of Cambridge, Ontario, to generate steam solely for the paper recycling process Power generated from the gas turbine electric generator is sold to the Ontario Electricity Financial Corporation under a contract that runs until 2018.
