Electrode Boiler As Alternative to Traditional Electric Boilers

This material is prepared on the basis of technical descriptions and recommendations of electrode boilers manufacturers. Reflects the most characteristic and important information related to the subject matter of the material.
Electrode boilers are used in closed heating systems with forced circulation of the coolant. In general, a number of capacities are designed to provide small and medium volumes of civil and industrial volumes. And average volumes of civil and industrial premises. But the use of an electrode boiler in the form of a boiler plant component makes it possible to provide heat and large volumes.
The electrode boiler is a flowing water heater. Structurally, the electrode boiler is a vessel with electrodes placed in it. El. Current, flowing through the coolant, heats it. As power supply of electrode boilers, AC power is used. In this case, the electrolysis of the coolant does not take place, since the cathode and anode each time change with a frequency of 50 hertz. The resistance of the coolant at a low temperature is higher than that of a heated coolant. As a result, the thermal power of the electrode boiler changes during the heating of the coolant, since its specific resistance varies .
An interesting technical solution for the design of the electrodes is realized in the electrode kettles of the Kitotherm. In KITOTHERM boilers where electrodes are assembled from separate segments. Such a design of the electrodes makes it possible to change the power of the electrode boiler to a greater or lesser extent. By changing the boiler's heat output, it is now possible to better adapt the boiler to the existing operating conditions, and also to increase or decrease it if necessary.
Electrode boilers have a number of positive qualities when compared with traditional boilers. The absence of a coolant when the boiler is connected to the mains does not lead to its failure. The reason is the absence of an electrical circuit, since there is no intermediate conductor-coolant between the electrodes. Scale, formed on the electrodes of the boiler, can not lead to their destruction, but only reduces the thermal power of the boiler due to a change in the conductivity of the medium in the space between the electrodes.
But like any other technique, electrode boilers require a number of conditions. In particular, they are demanding for the conductivity and the electrical resistance of the coolant. Firms manufacturers of electrode boilers are forbidden to use as a coolant - water from wells (rich in iron and can lead to a short circuit), sea water, automobile antifreeze. It is advisable to use - melted snow, drinking tap water, rainwater. Since distilled water dielectric is recommended to add to it, not iodized salt. Separate manufacturers of electrode boilers offer branded coolants, designed specifically for use with electrode boilers for their assembly. In the range there is also a special. Additives to adjust the thermal resistance of the coolant.
