  2. Electrode boiler - Wikipedia

    en.wikipedia.org/wiki/Electrode_boiler

    Electrode boilers can work on both single-phase and three-phase supplies. If DC voltage is used, electrolysis of water occurs, decomposing water into its elements H 2 at the cathode (negative electrode) and O 2 at the anode (positive electrode). The electrode boiler is 99.9% efficient with almost all the energy consumed producing steam. [1]

    Electric steam boiler on the training ship Golden Bear. An electric steam boiler is a type of boiler where the steam is generated using electricity, rather than through the combustion of a fuel source. Such boilers are used to generate steam for process purposes in many locations, for example laundries, food processing factories and hospitals ...

    Insert a piece of silver wire into concentrated HCl then allow the wire to dry on a lint-free cleaning cloth. This forms an insoluble layer of AgCl on the surface of the electrode and gives you an Ag/AgCl wire. Repeat dipping every few months or if the QRE starts to drift. Obtain a Vycor glass frit (4 mm diameter) and glass tubing of similar ...

    An electric boiler can be placed in operation quickly, as there is no furnace to reach high temperatures. [4] Environmental impact is displaced to the source of the grid electricity; however, if fossil fuel is being consumed to make electricity, overall efficiency will be lower than direct use of the fuel.

    The larger boilers were 15 feet 9 inches (4.80 m) in diameter and 20 feet (6.1 m) long, the smaller were 11 feet 9 inches (3.58 m) in length. All ends had three corrugated Morrison furnaces of 3 feet 9 inches (1.14 m) diameter, 159 furnaces in total, and a working pressure of 215 pounds per square inch (1,480 kPa).
