Steam generating system used for medium-high-voltage and high-power electrode

Abstract

The invention provides a steam generating system used for a medium-high-voltage and high-power electrode. The steam generating system comprises an electrode boiler, a steam heat exchanger, a heat storage container and a heat transporting exchanger. The electrode boiler, the steam heat exchanger, the heat storage container and the heat transporting exchanger are connected in order. The heat transporting exchanger is used for transporting heat to a user. A heat storage circulating pump is arranged between the heat storage container and the heat transporting exchanger. The electrode boiler is connected with a water treatment device which is used for preparation of pour water. A chemical feeding device which is used for feeding electrolyte is arranged between the electrode boiler and the water treatment device. By means of the system, high voltage power above 10KV can be connected to a boiler system without transformation equipment and corresponding power cable, so that the electric power loss and the cost of the electric power transmission and transformation can be reduced.

Description

technical field [0001] The invention relates to an electric power regulating system, in particular to a steam generation system for medium and high voltage electric high power electrodes. Background technique [0002] In the 1920s, Sweden invented the submerged high-voltage electrode boiler for the first time, which greatly improved the control accuracy. The improved design allowed high-voltage direct connection (6-15kV), which was called high-voltage electrode boiler. [0003] From the 1970s to the 1980s, the construction of nuclear power plants in Europe and the United States entered a peak period, and electrode steam boilers began to be used. Because there is no emission problem of oil and gas boilers, it is clean and environmentally friendly, and has a high degree of safety. Electrode steam boilers are generally accepted by the nuclear power industry as the start-up boilers for nuclear power. [0004] Steam boilers are divided into low-voltage resistance type and high-v...

AI Technical Summary

Problems solved by technology

[0006] Defects of existing technology: resistance heating method is adopted, which uses 380V low-voltage power supply, which restricts the total power of the boiler, and the maximum power of a single machine is 2.8MW

And this way of entering the line requires transformers, high and low voltage distribution cabinets, cables and bridges, and the investment in the power system is far greater than the investment in the heating host.

The heat storage temperature is low, which will cause power loss
