のためボイラーに供給する水は化学薬剤を用いて脱泡(
脱酸素)処理したり、アルカリ性を保つなどしてあらか
じめスケール防止処理をすることが必要である。[Problem to be solved by the invention] However, when oil, coal, natural gas, etc. are burned and used in boilers, etc., a combustion furnace is required, making it difficult to downsize and also impossible to move. . In addition, it is necessary to take safety measures such as fire and disaster prevention measures, and because the temperature difference between the heated part and the water or steam of the heated object is too large, so-called scale may adhere, reducing the heat transfer coefficient. The problem is that the tube will eventually break. For this reason, the water supplied to the boiler is degassed using chemical agents (
It is necessary to carry out scale prevention treatment in advance by deoxidizing) or maintaining alkalinity.
また、水中に電気抵抗ヒーターを入れると、熱源の近く
では水の沸騰点の1000Cよりはるかに高い温度で加
熱されるので、十分な境界面伝熱表面積を持たないヒー
ターを使用すると様々な障害か発生する。Also, when an electric resistance heater is placed in water, it will be heated to a temperature much higher than the boiling point of water (1000C) near the heat source, so using a heater that does not have sufficient interfacial heat transfer surface area may cause various problems. Occur.
そのうえ電気抵抗ヒーターはガスの燃焼などと同じく、

ながる。Moreover, electric resistance heaters, like gas combustion,
Because the temperature difference between the heating source and the water is so large, inorganic and organic components contained in the water are adsorbed and deposited on the surface of the heater, which acts as an insulator and reduces heat transfer. Water boils poorly. At the same time, the heat dissipation of the heater also deteriorates, leading to an accident in which the heater eventually breaks.

Since it is equipped with a metal material that can act as a magnetic flux path, when a commercial wavenumber AC power source is connected to the induction coil, low voltage and large current flow through the metal material that can act as a magnetic flux path on the bottom of the steam generation tank, based on the so-called transformer principle. Due to this large current, Joule heat is generated on the metal side of the bottom of the tank, and heating is performed efficiently.
