Abstract :
A STEAM generator no larger than an ordinary incandescent lamp has been developed by the lamp division of Westinghouse Electric and Manufacturing Company. Heating coils of the device are directly immersed in water, providing a thermal efficiency of 90 per cent. It can generate superheated steam from cold water in less than 15 seconds. The heater is made in 1,000-, 1,500-, and 2,000-watt sizes, with evaporating capacities up to 5.7 pounds of water per hour. Steam can be superheated by it to 350 degrees Fahrenheit.
