Description
There are two methods of utilizing electric power to generate steam in an electric boiler or steam generator. One is to pass electric current through a metal resistance-heating element immersed in water. The metal element resists the passage of current and develops heat, which by contact is conducted to the water and finally generates steam. The other method is to utilize the water itself as the resistance element carrying alternating current between solid metal electrodes. The resistance of the water to the passage of current produces internal heat that results in rapid steam generation.
