Electrode boiler
An electrode boiler (jet type) is a type of boiler that uses electricity flowing through streams of water to create steam. The conductive and resistive properties of water are employed to carry electric current. During the operation of the boiler, it is fed with water which contains conductive substances like salts. Because the departing steam is free of these substances, conductivity of water decreases as the cleaner the water, the lower the conductivity. When conductivity goes beyond certain limit, some of the water must be blown down and replaced with fresh water. The most common type of electrode boiler pumps water from the lower part of the vessel to an internal header that has nozzles that allow the water to flow to electrodes. The electrodes are connected to a high voltage A.C. source, typically 6,600 volts to 13,800 volts. If D.C. voltage is used, Electrolysis of water occurs, decomposing water into its elements H2 at the cathode(negative electrode) and O2 at the anode(positive electrode)}. Electrode boilers can work on both Single phase and Three phase supplies. The electrode boiler is 99.9% efficient with almost all the energy consumed producing steam.
