3 ms·gas turbines last much longer when run at constant optimal RPM than when constantly varying.by UltraSane 2y agogas turbines last much longer when run at constant optimal RPM than when constantly varying.Panzer04 2y agoMy naive presumption is that the gas turbines do run at constant RPM, but vary the fuel use to deliver more torque and hence energy? Maybe just wrong though :PUltraSane 2y agoI'm not sure. I do not that gas peaker plants that have to be started and stopped a lot wear out very fast.
