General Electric 7E

The 7E is a 60 hertz industrial gas turbine built by GE Vernova and sold today as the 7E.03. It is aimed at peaking, cyclic and baseload plants as well as liquefied natural gas and cogeneration sites, where its exhaust heat is used to raise steam. The maker rates it at about 90 MW in simple cycle and better than 52 percent efficiency in combined cycle, with NOx below 4 ppm without a catalytic reducer, and says it can reach full load in under ten minutes. A multiple-fuel combustion system lets operators switch fuels while running under load. The 7E carries a long history: the first E-class machine, a 7E, was put into service at the Shoreham Combustion Turbine plant in New York in 1971, and GE Vernova now counts a worldwide 7E fleet of more than 90 GW running in over 27 countries, with more than two million starts.
