An electrode boiler

Abstract

The invention relates to an electrode boiler that is adapted for use in a marine environment. The boiler includes a container (5) holding water, a number of electrodes (7a - f) submerged in said water, a source of AC electric power connected with said electrodes, means for supplying water to said container, means for removing hot water or steam from said container and means for holding the water in said container at a pre-defined level. In order to secure an even production from the electrodes even when the boiler is tilted, the electrodes are even in number and are arranged in a circle, wherein electrodes (7a - 7d; 7b - 7e; 7c - 7f) that are located at 180 DEG distance along said circle are connected to each other and to one phase of electric power from said source.

Description

technical field

[0001] The invention relates to an electrode type boiler which can provide hot water or generate steam. Background technique

[0002] Electrode boilers consist of several electrodes submerged in a tank, one for each phase. The boiler generates heat by means of an alternating current with water flowing as a conductor from the electrode to the counter electrode. The boiler is suitable for low-voltage (230-400V) and high-voltage (5-20KV) power sources, and the thermal power is about 2-100MW. Electrode boilers have many advantages, such as up to 100% efficiency, easy control of the output range, and quick start-up. In addition, the electrode boiler is also very environmentally friendly. Self-protected when the water level is low, this is because the boiler prevents the flow of electricity when the water level is low, so there is no catastrophic failure. However, electrode boilers have so far been limited to installations in stationary environments, ie inside ...
