Description

本発明は、既設の石炭使用の火力発電装置からCOを発生させないで発電することを特徴とする発電装置に関するものである。 The present invention relates to a power generation device that generates power without generating CO 2 from an existing coal-based thermal power generation device.

特許庁のホームページで「石炭使用火力発電装置 二酸化炭素発生ゼロ」ANDで検索したがヒット件数ゼロで、「火力発電装置 二酸化炭素発生ゼロ」ANDで検索してもヒット件数はゼロで比較出来る先行技術は見つけられなかった。
本願は、既設の石炭使用の火力発電装置からCO2を発生させず、転がり軸受が設けてある回転体B(2)に低トルク性を与える動力増幅装置に関するものであるが引用文献は見つけられなかった。
温暖化の元凶とされる石炭使用の火力発電装置による二酸化炭素の発生を抑える解決策として、ヨーロッパでは脱炭素化時代に突入しており、化石燃料を燃焼させて、電気エネルギーを生成することを禁止する方向に進んでいるのに対し、我が国は二酸化炭素を人為的に集め、地中、水中などに封じ込める二酸化炭素の貯留技術を開発して発生する二酸化炭素を少なくする低炭素化を目指している。
地球温暖化の元凶と承知しながらも脱炭素化に踏み切れない 最大の理由は石炭火力発電のコストが一番低いからである。
然し、世界的な潮流は確実に脱炭素化に傾いており、石炭使用の蒸気タービンの需要が激減し、前記蒸気タービンの在庫の山が発生し、蒸気タービンの安売りが起こり、海外の大手重電メーカーは大量の人員整理を発表した。
我が国も世界的な脱炭素化を無視出来ないので、(無視すると国際的に批判される)早晩脱炭素化時代が訪れる。
その時の対応策は敷地、送電網、発電機等、可能な限り既設の装置を活用することが一番合理的であり、前述した様に脱炭素化に踏み切れない 最大の理由が石炭火力発電のコストが一番低いことに起因しているから、そのコストより更に安い装置の開発になる。
従って、考慮される対策は石炭を使っている蒸気タービンだけを取替えてCO2を発生させないとともにコストも安くなる装置に置き換える代替案の開発が課題となる。
既設の石炭使用の火力発電装置の回転数と同じ回転数の回転体A(1)を設置するとともに単位当たりのコストが石炭を燃焼させる場合よりも安い装置として、電圧と周波数を変化させるインバーター(VVVF)制御方式の電動モーターで回転体A(1)を所定の回転数で回転させ,回転体A(1)を回転体B(2)に連結し、回転体B(2)に設けてある転がり軸受で回転体B(2)に低トルク性を与えることで前記石炭を使っている蒸気タービンだけを他の装置に置き換える代替案の開発が可能になる。
前記装置の運転コストは既設の石炭使用の火力発電装置で発生している例えば環境汚染防止対策の廃棄ガス中の窒素酸化物を取り除く脱硝装置、硫黄酸化物を取り除く脱硫装置等が不要になるのでこれら装置の保守、管理費用が不要になり、石炭の燃料代が不要になり、石炭を置いておく貯炭場の新規利用も可能になる等のメリットが期待されるので、蒸気タービン代替案の単位当たりのコストは石炭使用の火力発電より安くなる。
Prior art that can be compared with zero hits even if you search with "thermal power plant carbon dioxide generation zero" AND search with "coal-use thermal power plant carbon dioxide generation zero" AND on the JPO homepage Was not found.
The present application relates to a power amplifying apparatus that does not generate CO2 from an existing coal-fired thermal power generation apparatus and gives low torque to a rotating body B (2) provided with a rolling bearing. It was.
Europe has entered a decarbonization era as a solution to suppress the generation of carbon dioxide by coal-based thermal power generation equipment, which is considered to be the cause of global warming, to generate electric energy by burning fossil fuels. Japan is aiming to reduce carbon emissions by developing carbon dioxide storage technology that artificially collects carbon dioxide and keeps it in the ground and in the water, etc. Yes.
The biggest reason for not being able to decarbonize while knowing that it is the cause of global warming is because the cost of coal-fired power generation is the lowest.
However, the global trend is definitely leaning toward decarbonization, the demand for steam turbines using coal is drastically reduced, the piles of steam turbines are invented, the steam turbines are sold cheaply, An electric manufacturer announced a large number of personnel arrangements.
Since Japan cannot ignore global decarbonization, the decarbonization era will come sooner and later (which will be criticized internationally).
The most effective reason for this is to use existing equipment as much as possible, such as the site, power grid, and generator, and as mentioned above, the biggest reason for not being able to decarbonize is coal-fired power generation. Because it is due to the lowest cost, the development of a device that is even cheaper than that cost.
Therefore, the issue to be considered is the development of an alternative that replaces only steam turbines that use coal and replaces them with equipment that does not generate CO2 and that also reduces costs.
An inverter that changes the voltage and frequency as a device that installs the rotating body A (1) having the same rotational speed as that of an existing coal-based thermal power generation apparatus and has a lower cost per unit than that of burning coal. Rotating body A (1) is rotated at a predetermined rotational speed by an electric motor of VVVF) control system, and the rotating body A (1) is connected to the rotating body B (2) and provided on the rotating body B (2). By giving the rotating body B (2) low torque with a rolling bearing, it is possible to develop an alternative that replaces only the steam turbine using the coal with another device.
The operating cost of the above equipment is not required for denitration equipment that removes nitrogen oxides in waste gas, for example, environmental pollution prevention measures, desulfurization equipment that removes sulfur oxides, etc. that are generated in existing coal-fired thermal power generation equipment The maintenance and management costs for these devices are no longer required, the fuel cost of coal is not required, and the benefits such as the possibility of new use of the coal storage where the coal is placed are expected. The cost per unit is cheaper than thermal power generation using coal.

The rotating speed is set to a predetermined rotating speed by a stepping motor type excitation circuit. It is controlled and transmitted to the generator (53), and the various tasks associated with the operation of the existing coal-fired thermal power generation apparatus are no longer necessary, thereby reducing the cost per unit and solving the problem.

石炭使用の火力発電装置は二酸化炭素発生の元凶なので、CO2削減の国際公約の実現の一助になり、環境汚染防止対策の廃棄ガス中の窒素酸化物を取り除く脱硝装置、硫黄酸化物を取り除く脱硫装置等が不要になるのでこれら装置の保守、管理費用が不要になり、石炭の燃料代が不要になり、石炭を置いておく貯炭場の新規利用も可能になり、単位当たりのコストが石炭使用の火力発電より安くなる。尚コスト比較は段落0017で別途詳述する。 Coal-based thermal power generation equipment is the main cause of carbon dioxide generation, helping to realize the international commitment to reduce CO2, denitrification equipment to remove nitrogen oxides in waste gas for environmental pollution prevention measures, desulfurization equipment to remove sulfur oxides This eliminates the need for maintenance and management costs for these devices, eliminates the need for coal fuel, and makes it possible to newly use coal storage facilities where coal is placed. It becomes cheaper than thermal power generation. The cost comparison will be described in detail in paragraph 0017.

The rotating body of the self-aligning ball bearings A1 and B2 A torque required to generate a predetermined power generation amount is secured by adding the rotational force of a ball rotating in the rotational direction of the rotating body B (2) and the rotational force of the stepping motor type excitation circuit of the five-phase excitation. The rotation of the stepping motor type excitation circuit at 1830 times / rpm is maintained, and this rotational speed is transmitted to the generator (53) to enable induction power generation.

本発明と石炭使用の火力発電装置との運転コストの比較について
・ 本発明の運転コストはステッピングモーター型励磁回路を作動させる電力料と電動モーターを作動させる電力料だけである。
・ 石炭を使用する火力発電の運転コスト
本発明で設置されている回転体A(1)に置き換えられ削減可能な石炭を使用する火力発電の装置及び費用は、
燃料の石炭代金
石炭を粉状にする破砕機の補修及び管理費、
ボイラーの補修及び管理費、
蒸気タービンの補修及び管理費、
復水器の補修及び管理費、
冷却水あげの補修及び管理費、
廃棄ガス中の窒素酸化物を取り除く脱硝装置の補修及び管理費、
硫黄酸化物を取り除く脱硫装置補修及び管理費、
燃焼灰(フライアッシュ)の対策費等である。
本発明と石炭使用の火力発電装置との運転コストの差は上記1から2を引いた金額で求められ、その金額がマイナスなら本発明の方が安く、プラスなら火力発電の装置が安くなる。
1と2を比較すると1から2を引いた金額はマイナスであることは明白であるから本発明の方が安いことになる。
上記では両者に携わる人件費は計算に入れていないが1に従事する人数より2に従事する人数が多いのでコスト差は更に大きくなるのに加えて石炭を置いておく貯炭場の新規利用も見込まれる。
Comparison of operation costs between the present invention and a coal-fired thermal power generation system-The operation costs of the present invention are only the power charge for operating the stepping motor type excitation circuit and the power charge for operating the electric motor.
・ Operating cost of thermal power generation using coal
The apparatus and cost of thermal power generation using coal, which can be reduced by replacing the rotating body A (1) installed in the present invention,
The cost of repairing and managing the crusher that makes coal into a powdered coal
Boiler repair and management costs,
Steam turbine repair and management costs,
Condenser repair and management costs,
Cooling water repair and management costs,
Repair and management costs for denitration equipment that removes nitrogen oxides in waste gas,
Desulfurization equipment repair and management costs to remove sulfur oxides,
This is the cost for measures against combustion ash (fly ash).
The difference in operating cost between the present invention and the thermal power generation apparatus using coal is determined by the amount obtained by subtracting 2 from 1 above. If the amount is negative, the present invention is cheaper, and if it is positive, the thermal power generation apparatus is cheaper.
When comparing 1 and 2, it is clear that the amount obtained by subtracting 1 from 2 is negative, so the present invention is cheaper.
In the above, the labor costs for both parties are not included in the calculation, but the number of people engaged in 2 is larger than the number of people engaged in 1, so the cost difference will be even larger, and in addition, the use of a coal yard where coal will be placed is expected It is.
