主ボイラ１へ供給される。The high temperature exhaust gas from the main boiler 1 passes through the flue 2 to the reboiler 6.
After being heated, it is discharged from the chimney 20, but the hot water in the reboiler filter and the generated steam' enter the deaerator 4Vc as a two-phase flow, and the steam flows from the main boiler 1 to the pipe 19. The hot water is mixed with the steam introduced through the steam introduction pipe 7 and used to deaerate the feed water, and the deaerated hot water is circulated to the reboiler 6, and a portion is supplied to the main boiler 1 as described above.
脱気器と煙道との位置関係を適切に配置すると、このリ
ボイラへの循環は比重差を利用して行なうことができ、
全く動力を用いずに実ｆｌｌｊすることができる。By arranging the positional relationship between the deaerator and the flue appropriately, circulation to the reboiler can be performed by utilizing the difference in specific gravity.
It is possible to perform actual fullj without using any power.
この点で不発明はリボイラを設置するだけで廃熱回収及

でき、省エネルギに相応しい脱気装置となる。The present invention includes a reboiler installed in a flue of a main boiler, a deaerator connected to the reboiler through a hot water circulation pipe and a generated steam pipe, and supplying deaerated water from the deaerator to the main boiler. This energy-saving deaerator is equipped with a connecting pipe, a steam introduction pipe to the deaerator, a water supply pipe, and an exhaust pipe, so the waste heat from the main boiler is recovered by the reboiler, and the generated steam is used to supplement the deaerator. By introducing the traditional main boiler, it consumes 10 to 15
% steam amount can be reduced to about 5 to 8%, depending on the operating conditions, resulting in a degassing device suitable for energy saving.
また給水は脱気器とリボイラとの間を循環して、廃熱を
