Abstract :
A fully supercharged steam turbine-generator which utilizes a unique conductor cooling system in the generator stator has been developed at Allis-Chalmers Manufacturing Co., Milwaukee, Wis. Copper coil strands in the stator are transposed around a total of 6,000 feet of rectangular stainless tubing. Hydrogen gas passes through the tubing at velocities up to 10,000 feet per minute, transferring heat from the stator coils, keeping them at desirable temperatures.
