BACKGROUND ART

As four major energy sources of our country, there are petroleum, coal, nuclear power, and liquefied nature gas (LNG) in sequence. In the future, it is expected that the proportion of the petroleum and coal will be decreased, whereas the proportion of the nuclear power and LNG will be increased. Meanwhile, alternative energy is still insufficient as a realistic alternative due to the insufficiency of a technological level and market foundation furtherance, but a strong political will of the government and the conduct of supporting policy are urgently needed.

Energy experts argue “coal will be considerably depleted in fifty years,” and “the development of alternative energy such as photovoltaic power generation, wind power generation, or landfill gas-to-electricity projects needs to be accelerated.” However, in order to actively develop domestic alternative energy, it has been pointed out that problems such as a low technical level, the lack of professional manpower and an insufficient investment scale need should be solved.

In current thermal power generation, there are problems such as pollution and environment destruction, and in the nuclear power generation, there is a serious danger such as the Chernobyl nuclear accident and the Fukushima nuclear accident. However, the nuclear power generation has been used all over the world.

DESCRIPTION OF MAIN REFERENCE NUMERALS OF DRAWINGS

An embodiment of a power generating device using an electric furnace according to the present invention will be described with reference toFIGS. 1 to 5.

The power generating device using an electric furnace according to the present invention includes an electric furnace10, a steam separator15, a steam pipe20, a turbine25, a power generator30, a condenser35, and a super-heater40.

The electric furnace10heats water to produce high-temperature and high-pressure steam. To achieve this, the electric furnace10includes a housing11, a plurality of heat-radiation-rod cases14, a plurality of heat radiation rods12, and a fixing member13.

The housing11accommodates water. The heat radiation rods12are attached to the housing11, and produce steam by heating the water accommodated in the housing11by using electricity. To achieve this, the heat-radiation-rod cases14are provided at the housing11such that the heat radiation rods12are attached to the housing11.

The heat-radiation-rod case14serves to attach the heat radiation rod12, and is attached by being inserted in a radial direction from the outside of the housing11such that one end14ais fixed to the external side of the housing11to allow the heat radiation rod12to be attached from the outside. The plurality of heat-radiation-rod cases14is attached in a circumferential direction along the circumferential direction of the housing11, and the plurality of heat-radiation-rod cases that is attached along the circumferential direction are formed as multiple layers. In this case, when water is heated to produce steam, the heat-radiation-rod cases14may be shaken due to the steam. In order to prevent this, the fixing member13serves to fix the heat-radiation-rod cases12within the housing11. The fixing member13is provided in a vertical direction at the center of the housing11, and fixes the other ends12bof the heat-radiation-rod cases14. That is, the fixing member13is fixed while being vertically erected state at the center of the housing11, and the other ends12bof the heat-radiation-rod cases14are fixed to the fixing member13. The upper portion of the fixing member13is fixed to the housing11so as not to be shaken. The heat radiation rods12can be attached by being respectively inserted into the heat-radiation-rod cases14from the outside. When the heat radiation rod12is used for a long time, since the lifespan thereof expires, the heat radiation rod needs to be replaced with new one. In this case, it is possible to replace the heat radiation rod12by separating the heat radiation rod from the heat-radiation-rod case14. When electricity is supplied to the heat radiation rods12, the heat radiation rods12are heated, and the water within the housing11is heated to produce steam.

When the steam is produced within the housing11, the steam separator15serves to filter only the steam and to send the filtered steam to the steam pipe20. To achieve this, the steam separator15includes steam filter plates16at multiple stages.

A plurality of penetrating holes17is formed in the steam filter plate16, and the steam can be ejected through the penetrating holes17. Filter protrusions18that vertically protrude so as to surround the penetrating holes17are formed on the steam filter plate16. The steam filter plates16are provided at the upper portion of the housing11at multiple stages, and in this case, the steam filter plates16are provided such that the penetrating holes17are deviated from one another on the steam filter plates16. Thus, when the water boils in the housing11and is discharged through the penetrating holes17, a part of moisture forms on the filter protrusions18by primarily colliding with the filter protrusions18, and the rest is discharged through the penetrating holes17. Meanwhile, since the steam filter plates16are formed at multiple stages and the penetrating holes17are deviated from one another in this case, moisture is removed while being discharged through the penetrating holes17at the respective stages, and only steam can be ejected to the steam pipe20. Although not shown in the drawings, in this case, the steam filter plate16is preferably formed in a convex shape such as a substantially dome shape. In this case, the steam can be more easily gathered, and thus, it is possible to discharge the steam.

The steam pipe20serves to guide the steam generated in the housing11to the turbine25. In this case, in order to increase the temperature and pressure of the steam in the steam pipe20, it is necessary to heat the steam discharged to the steam pipe20. To achieve this, the plurality of heat-radiation-rod cases14and the plurality of heat radiation rods12are provided at the steam pipe20. In this case, in order to prevent shaking due to the flow of the steam, the heat-radiation-rod cases14are provided such that both ends thereof are fixed to the steam pipe20. When the heat-radiation-rod cases14are fixed to the steam pipe20, it is possible to attach the heat radiation rods12by being respectively inserted into the heat-radiation-rod cases14from the outside. The heat radiation rods12provided at the steam pipe20increase the pressure and temperature of the steam by heating the steam flowing through the steam pipe20. Meanwhile, when the heat-radiation-rod cases14are provided at the steam pipe20, the heat-radiation-rod cases are preferably provided such that inlets of the heat-radiation-rod cases14are deviated from one another.

The turbine25is provided at an outlet of the steam pipe20, and is operated by the steam discharged from the steam pipe20.

The power generator30is connected to the turbine25such that the power generating unit is operated by the turbine25to produce electricity.

The condenser35cools the steam discharged from the turbine25into water after the turbine25is operated.

The super-heater40heats the water cooled in the condenser35, and supplies the heated water to the electric furnace10. The turbine25, the power generator20, the condenser35and the super-heater40have the same configurations as those in the power generating device of the related art, and thus, the detailed description thereof will be omitted.

When the heat radiation rods12within the housing11of the electric furnace10are heated, the water accommodated in the housing11is heated to produce the steam. When the steam is produced, an ascending air current is generated, and thus, the heat radiation rods12may be shaken. However, the heat radiation rods12are provided in the heat-radiation-rod cases14, one ends14aof the heat-radiation-rod cases14are fixed to the housing11, and the other ends14bthereof are fixed to the fixing member13. Thus, it is possible to prevent the heat-radiation-rod cases14from being shaken.

The steam generated in the housing11is discharged to the penetrating holes17of the steam filter plates16, and passes through the penetrating holes17of the steam filter plates16provided at multiple stages. Thus, only the steam is discharged, and is introduced to the steam pipe20. The steam introduced to the steam pipe20is heated one more time in the steam pipe20by the heat radiation rods12provided at the steam pipe20, and thus, the temperature and pressure of the steam are increased. The steam whose pressure is increased by passing through the steam pipe20is discharged to the turbine25to operate the turbine25. The turbine25operates the power generator30, and thus, electricity is generated.
