Abstract

PROBLEM TO BE SOLVED: To solve problems that at present, electric power circumstances in Japan are affected by the stoppage of nuclear power plants after the earthquake disaster, and by cost increase of fuels such as coal, petroleum or natural gas of fuels for thermal power generation that are made to soar due to an increased demand and a low yen rate of money order, so that the management of electric companies is greatly compressed in a current state, particularly, concerning a nuclear power plant, the re-operation is in a troubled situation due to a dissenting opinion against a nucleus or a safety problem to the nucleus, and also there are many opinions about reactor decommissioning, however, even if performing the reactor decommissioning, the requirements for enormous costs are concerned about.SOLUTION: To solve these problems, fuels 9 such as coal, petroleum or natural gas are replaced with electric heaters 12, in a thermal power plant in selection Fig. 1. Also, all of nuclear fuel rods 10 and control rods 11 are taken out from the inside of a pressure vessel 14 and are replaced with the electric heater rods 13, in a nuclear power plant in selection Fig. 2.

Description

この発明は、ボイラーや圧力容器内で水を熱して水蒸気に変え、その水蒸気でタービンを回転させ、そのタービンに連結された発電機を回し発電する火力発電に関する。  The present invention relates to thermal power generation in which water is heated to change into steam in a boiler or a pressure vessel, a turbine is rotated by the steam, and a generator connected to the turbine is rotated to generate power.

火力発電所では、ボイラーの中で石炭、石油、天然ガスなどを燃料として燃やし、水を沸騰させて水蒸気を発生させ、その水蒸気の力でタービンを回しタービンと連結された発電機で電力を得ている。しかし、石炭、石油、天然ガスなどの燃料の価格も高騰して電力会社の経営を圧迫している。東北大震災後、電力の問題は国を挙げての大きな関心事である。原子力発電所の停止に伴い、古い火力発電所までもフル稼働の状況が続いており、電気料金の値上げも検討され国民への負担増も避けて通れない状況にある。  In a thermal power plant, coal, oil, natural gas, etc. are burned as fuel in a boiler, water is boiled to generate steam, and the turbine is rotated by the power of the steam to generate power from a generator connected to the turbine. ing. However, the prices of fuels such as coal, oil, and natural gas have soared, putting pressure on the management of electric power companies. After the Tohoku Earthquake, the power problem is a major national concern. With the shutdown of the nuclear power plant, even the old thermal power plant continues to be in full operation, and the increase in electricity charges has been studied and the burden on the public cannot be avoided.

原子力発電所においては、核燃料棒と制御棒を水の入った圧力容器の中に置き燃料として熱を発生させ、水を沸騰させて水蒸気を得ている。その発生させた水蒸気でタービンを回し、タービンと連結した発電機で電力を得ている。しかし、核への安全性の問題や、設置場所の安全性などさまざまな要因で再稼動もままならない状況にある。廃炉に向けての意見もあるが、それにしても膨大な費用がかかる試算もある。  In a nuclear power plant, nuclear fuel rods and control rods are placed in a pressure vessel containing water, heat is generated as fuel, and water is boiled to obtain water vapor. The turbine is rotated by the generated steam, and electric power is obtained by a generator connected to the turbine. However, due to various safety factors such as nuclear safety issues and the safety of the installation site, there is a situation where restarting does not remain. There are opinions towards decommissioning, but there are some calculations that cost a lot.

しかしながら、以上の技術によれば、石炭、石油、天然ガスなどの燃料は価格変動に左右されることとなり、経営の改善、電気料金の安定が得にくい状況は変わらない。
原子力発電所においても、核燃料棒を使用している以上、すぐに国民の理解を得て全面稼動が実現できる可能性は低い。
そこで、この発明は、石炭、石油、天然ガスなどの燃料や、核燃料棒などの核を一切使用しない火力発電所を実現することを課題とする。However, according to the above technology, the price of fuels such as coal, oil, and natural gas is affected by price fluctuations, and the situation in which it is difficult to improve management and stabilize electricity prices remains the same.
At nuclear power plants, as long as nuclear fuel rods are used, it is unlikely that full operation will be realized with immediate public understanding.
Accordingly, an object of the present invention is to realize a thermal power plant that does not use any fuel such as coal, oil, or natural gas, or a nucleus such as a nuclear fuel rod.

以上の課題を解決するために、第一発明は、現在ある施設、設備を出来る限りそのまま使用し、石炭、石油、天然ガスなどの燃料を電気ヒーターに置き換えることを特徴とする火力発電所。  In order to solve the above problems, a first invention is a thermal power plant characterized in that existing facilities and equipment are used as much as possible, and fuel such as coal, oil, natural gas is replaced with an electric heater.

また、第二発明は、現在ある施設、設備をできる限りそのまま使用し、原子力発電所の核燃料棒や、制御棒を電気ヒーター棒に置き換えることを特徴とする火力発電所。  The second invention is a thermal power plant characterized in that the existing facilities and equipment are used as much as possible and the nuclear fuel rods and control rods of the nuclear power plant are replaced with electric heater rods.

第一発明によれば、石炭、石油、天然ガスなどの燃料から電気ヒーターに置き換ることにより価格変動や、為替変動による経営への影響を大幅に減らすことが出来るほか、環境への影響も軽減が可能になる。  According to the first invention, by replacing fuel such as coal, oil and natural gas with electric heaters, it is possible to greatly reduce the impact on management due to price fluctuations and exchange rate fluctuations, as well as impact on the environment. Mitigation is possible.

または第二発明によれば、核燃料棒や制御棒を電気ヒーター棒に置き換えることにより、核に対しての反対意見、再稼動に対しての理解が得やすくなるほか、廃炉に掛かる費用も大幅に節減できる。  Or, according to the second invention, by replacing nuclear fuel rods and control rods with electric heater rods, it becomes easier to obtain an objection to nuclear weapons and an understanding of restart, and the cost of decommissioning is also significant. Can save you.
