Description

Technical Field

[0001] The utility model relates to the technical field of dust reduction, in particular to a graphite anti-scaling electrode boiler. Background Art

[0002] An electrode boiler is a highly efficient, zero-pollution energy supply device that can directly insert high voltage electricity into water with a certain conductivity. Water acts as both a resistor and a heat transfer medium. After the water is heated into steam or high-temperature water, it is supplied to users through heat exchange equipment.

Although scale will not adhere to the boiler, its particles will still settle to the bottom of the water. When the scale particle content in the water is too high, the resistivity of the water will be reduced, thereby reducing the heating efficiency of the boiler. Utility Model Content
