構成されている。 A boiler for thermal power or nuclear power generation or an industrial boiler is provided with a deaerator as an auxiliary equipment thereof. A deaerator aims at degassing (particularly oxygen removal) in boiler feed water and increasing the temperature of the feed water, and generally consists of a deaerator section and a storage tank section.

せ、純水中の酸素除去を図つている。 However, when water is supplied to the boiler at startup, it is first necessary to remove oxygen from the pure water stored in the storage tank of the deaerator. A device is installed to recirculate the pure water in the storage tank section to the degassing section to remove oxygen from the pure water.

is returned to the deaerator inlet water supply pipe 9 through various valves 6, 7, and 8 by the operation of the deaerator recirculation pump 5, which is provided separately from the boiler feed water pump 4, and the water is returned to the deaerator inlet water supply pipe 9. The gas is recirculated to 2b for deaeration.

ペースも考慮しなければならないなどの問題があ
つた。 In this way, in the past, a deaerator recirculation device was provided completely independently, but this recirculation device was only used for about 1 to 2 hours when the boiler was started, and was not used for a long time during normal operation of the boiler. Considering that it is a device that does not need to be installed, there are problems such as having to take into account a wide variety of components such as pumps and piping, the cost of equipment is high, and the installation space must be taken into consideration.
本考案は、このような従来の問題を解消するた

たものである。 That is, in the present invention, there is a boiler feed pump installed in the boiler water supply pipe to increase the pressure and send water to the boiler downstream of the deaerator, and the boiler water supply pump outlet side part of the boiler water supply pipe and the deaerator are connected to each other. A deaerator inlet stop valve of this deaerator piping is opened when the boiler feed water pump is operated at low flow rate. Focusing on increasing the flow rate passing through the boiler feed water pump and returning it to the deaerator storage tank, we branched the deaerator recirculation pipe from the upstream part of the deaerator inlet stop valve of the existing overheating prevention piping. and connect it to the water supply pipe at the inlet of the deaerator.
This deaerator recirculation pipe is provided with a stop valve and a check valve, thereby simplifying the deaerator recirculation device.

４が設けられている。 In the drawing, a deaerator recirculation pipe designated by reference numeral 10 connects the storage tank section 2a of the deaerator 2 and the boiler feed pump 4 outlet side portion of the boiler feed pipe 11 provided downstream of the deaerator. The deaerator inlet stop valve 15 of the deaerator inlet stop valve 15 of the overheat prevention piping 12 is branched from the upstream side and connected to the deaerator inlet water supply pipe 9, and the deaerator recirculation pipe 10 is equipped with a stop valve 13 and a check valve 1.
4 is provided.

とにより脱気を図る。 When the boiler is started, the stop valve 13 of the deaerator recirculation pipe 10 is opened and the deaerator inlet stop valve 15 of the desuperheating prevention pipe 12 is closed, and the storage tank of the deaerator 2 is activated by the operation of the boiler feed water pump 4. Part 2
Deionized water 3 stored in a is connected to overheating prevention piping 1
2. Deaeration is achieved by recirculating to the deaerator section 2b of the deaerator 2 through the deaerator recirculation pipe 10 and the water supply pipe 9 at the inlet of the deaerator section.

なるなど種々の効果が得られる。 As described above, according to the present invention, the deaerator recirculation device is installed using existing overheating prevention piping and boiler feed water pumps, so the conventional deaerator recirculation device is completely independent. This eliminates the need for deaerator recirculation pump equipment, etc., which would be required in a configuration where the plant is installed as a fuel cell, and also simplifies the associated piping, valves, and electrical equipment, significantly reducing plant construction costs. There is more space available for equipment arrangement in the plant, and since the deaerator recirculation pump is omitted, only the boiler feed water pump needs to be operated, making it easier to operate the boiler when starting up, and various other effects can be obtained.
