English firm orders turbine-generators with 36-inch blades

Two single-shaft steam turbine-generators have been commissioned by English Electric for the Central Electricity Generating Board´s Blyth “B” power plant in Northumberland, England. The turbines have 36-inch blades in the last rows of the low-pressure rotors. This is the world´s first application of blades of such length at speeds of 3,000 rpm and more, and these machines are the first of a series that English Electric is building with blades of this size.
