気ヒータ５とからその主要部が構成されている。The electric once-through steam boiler 1 is mainly composed of a header 2, 3, a water pipe 4, and an electric heater 5.
ヘツダ2,3は、上下のもので、この例では、円筒状を
呈して両端が閉塞され、水平に配されている。The heads 2 and 3 are upper and lower, and in this example, they have a cylindrical shape, both ends are closed, and are arranged horizontally.
水管４は、上下のヘツダ2,3の間に離脱可能に接続し
た複数のもので、この例では、円筒状を呈して上端が閉
塞されていると共に、下端が開放され、垂直に配されて
上下のヘツダ2,3の前側と後側に横方向に所定間隔を置
いて三つづつずらして設けている。The water pipe 4 is a plurality of pipes detachably connected between the upper and lower heads 2 and 3. In this example, the water pipe 4 has a cylindrical shape with its upper end closed and its lower end opened and arranged vertically. The front and rear sides of the upper and lower heads 2 and 3 are laterally spaced at predetermined intervals and are provided in three shifts.
而して、水管４の上方側部と上ヘツダ２の側部、並び
に水管４の下方側部と下ヘツダ３の側部とは、水平な上
下の連結管6,7に依り接続されていると共に、上下の連
結管6,7は、二分割されて離脱可能に取付けられてい
る。Thus, the upper side portion of the water pipe 4 and the side portion of the upper header 2 and the lower side portion of the water pipe 4 and the side portion of the lower header 3 are connected by horizontal connecting pipes 6 and 7. At the same time, the upper and lower connecting pipes 6 and 7 are bisected and detachably attached.
電気ヒータ５は、水管４内に離脱可能に挿入したＵ状
のもので、この例では、水管４の下部開口から水管４内
に挿入されて基部が水管４の下部に離脱可能に取付けら
れて居り、電源（図示せず）に接続されている。The electric heater 5 is a U-shaped member that is detachably inserted into the water pipe 4. In this example, the electric heater 5 is inserted into the water pipe 4 through the lower opening of the water pipe 4 and the base portion is detachably attached to the lower portion of the water pipe 4. You are there and connected to a power source (not shown).
尚、上ヘツダ２には、蒸気弁８と安全弁９が接続さ
れ、蒸気弁８には、蒸気負荷（図示せず）が接続され
る。A steam valve 8 and a safety valve 9 are connected to the upper header 2, and a steam load (not shown) is connected to the steam valve 8.
下ヘツダ３には、下ヘツダ３、下連結管７、水管４内
に水を供給する給水ポンプ10が接続されている。A water supply pump 10 for supplying water into the lower header 3, the lower connecting pipe 7, and the water pipe 4 is connected to the lower header 3.
上ヘツダ２と下ヘツダ３との間には、供給ポンプ10を

いる。A water level controller 11 that controls the supply pump 10 to maintain the water level at a predetermined value is provided between the upper head 2 and the lower head 3.
次に、この様な構成に基づいて作用を述解する。 Next, the operation will be described based on such a configuration.
電気ヒータ５に通電すると、水管４内の水が加熱され
て水管４の上部から蒸気が発生する。When the electric heater 5 is energized, the water in the water pipe 4 is heated and steam is generated from the upper part of the water pipe 4.
発生した蒸気は、水管４の上部から上連結管６→上ヘ
ツダ２→蒸気弁８を経て蒸気負荷へ送られる。The generated steam is sent to the steam load from the upper part of the water pipe 4 through the upper connecting pipe 6-> the upper header 2-> the steam valve 8.
水管４は、上下のヘツダ2,3に対して離脱可能に接続
されていると共に、電気ヒータ５は、水管４に対して離
脱可能に挿入されているので、上下のヘツダ2,3から水
管４を外した後に、水管４から電気ヒータ５を外す事が
できると共に、逆順に依り組立てる事ができる。Since the water pipe 4 is detachably connected to the upper and lower headers 2 and 3, and the electric heater 5 is removably inserted into the water pipe 4, the water pipe 4 is detached from the upper and lower headers 2 and 3. After removing, the electric heater 5 can be removed from the water pipe 4 and can be assembled in the reverse order.
従つて、ボイラ１の上方（若しくは下方）に大きな空
間がなくても、電気ヒータ５を容易に交換する事ができ

又、上下のヘツダ2,3に対して水管４を離脱可能に接
続したので、水管４にピッチング等が発生して損傷して
も、これを容易に交換する事ができる。Further, since the water pipe 4 is detachably connected to the upper and lower headers 2 and 3, even if the water pipe 4 is damaged due to pitching or the like, it can be easily replaced.
更に、電気ヒータ５を水管４の下部から水管４内に挿
入したので、電気ヒータ５が蒸気部に露出して過熱損傷
するのを防止する事ができる。Furthermore, since the electric heater 5 is inserted into the water pipe 4 from the lower part of the water pipe 4, it is possible to prevent the electric heater 5 from being exposed to the steam portion and being overheated and damaged.
