This turbine-upgrade delivers 10% more power

| By Chemical Engineering

For oil-and-gas and power-generation applications, the RB211 gas-turbine systems have already proven themselves, with more than 700 units now recording over 30 million operating hours. Now, the manufacturer has developed the RB211-Gzero retrofit upgrade, which provides users of industrial RB211-C and RB211-G gas generators, utilizing RT-56 and RT-62 power turbines, with a nominal 10% power increase, depending on ambient temperature. The RB211-Gzero upgrade can be easily achieved with minimal modification to the existing package design during routine unit overhaul. — Rolls-Royce, Warwick, U.K.
