Electrode steam boiler and working method thereof

Abstract

The invention relates to an electrode steam boiler and a working method thereof. The electrode steam boiler comprises a boiler body; the upper part of the boiler body is steam storage space; boiler water is accommodated in the lower part of the boiler body; and a water feeding pipe and a main steam valve are arranged on the boiler body. The electrode steam boiler is characterized by further comprising a center cylinder arranged at the upper part of the boiler body; one part for heating of a high-voltage electrode is dipped in the water in the center cylinder; and a water circulating system is arranged between the center cylinder and the lower part of the boiler body. The water circulating system comprises a circulating water pump, a circulating pipeline, a center cylinder bottom water inlet pipe and a center cylinder water falling pipe; one end of the circulating pipeline communicates with the lower part of the boiler body, and the other end of the circulating pipeline communicates with the center cylinder bottom water inlet pipe; the circulating water pump is arranged on the circulating pipeline; and a valve is arranged on the center cylinder water falling pipe. As the steam space of the boiler is large, the water carrying rate of output steam is low, and the quality is high. The lower part of the high-voltage electrode is dipped in the water in the center cylinder, so that safety, reliability, stability and high efficiency are achieved.

Description

technical field [0001] The invention belongs to the technical field of boilers, and in particular relates to an electrode type steam boiler and a working method thereof. Background technique [0002] With the implementation of national energy conservation and emission reduction policies, new energy sources have developed rapidly, and a large number of clean energy sources such as solar energy and wind energy have been established in China. At the same time, due to the country's transformation of high-energy-consuming industries and the elimination of some backward production capacity, my country's demand for energy has also gradually decreased to a certain extent. Therefore, my country's demand for electricity has grown slowly in recent years, resulting in The abandonment of light and wind in the region is serious. How to accommodate these abandoned solar and wind, the state has introduced relevant preferential policies. At the same time, in order to reduce emissions and re...

Problems solved by technology

[0006] 2) The heating of the boiler is star-connected, the furnace body is the center point, there is a large leakage current, and an isolation transformer must be used, otherwise it will not work

[0007] 3) The three phases of the boiler are unbalanced, and there is a certain leakage current in the furnace body. If the furnace body fails to ground, a safety accident will occur
