Rolls-Royce launches RB211-Gzero power upgrade for industrial gas turbines
Tuesday, 25 September 2012
Rolls-Royce, the global power systems company, has today launched RB211-Gzero, a retrofit upgrade product that provides many existing users of industrial RB211 aeroderivative gas turbine engines with a nominal power increase of ten per cent depending on ambient temperature and engine type.
Scott DeWolfe, Rolls-Royce, RB211 Product Director – Energy, said: “The RB211 is the most reliable and easily maintained industrial gas turbine available in its class today. The new RB211-Gzero delivers an additional ten per cent more power that will be critical to boosting performance and profitability for our customers in the global power generation and oil & gas sectors.”
Engineered as a modular package for ease of maintenance, the RB211-Gzero product will specifically benefit operators of the 440-plus worldwide installed fleet of RB211-C and RB211–G variant gas generators that feature RT-56 or RT-62 power turbines.
The RB211-Gzero power increase is achieved during routine gas turbine overhaul by retrofitting applicable RB211 units with a modular package that increases the flow of air through the engine, thereby increasing power availability at ISO conditions by 10 per cent for the RB211-G, and up to 31 percent for the RB211-C, depending on existing package configuration. This simple retrofit approach requires minimal modification to the existing gas turbine and also ensures that oil & gas production and power generation facility down-time is kept to a minimum.
With over 700 units sold, recording over 30 million operating hours, the industrial RB211 gas turbine is available in a power range of 29 to 44 megawatts (MW) and provides an ideal solution for onshore and offshore oil & gas and power generation applications.
The RB211-Gzero product was announced at the 2012 Turbomachinery Symposium taking place in Houston, Texas, USA.
