Steam is supplied to the heating medium evaporator to evaporate the heating medium into steam, and the vapor of this heating medium is
LPG is sent to the LPG evaporator and evaporated, but by controlling the pressure of the heating medium vapor to always be lower than the pressure of the steam that is the heating source,
This prevents the heating medium from mixing with the steam, and at the same time, by using steam as the heating medium, natural circulation is caused by the pressure of the steam and the condensation pressure, thereby reducing the installation area of pumps and the like.
以下この考案の一実施例を図面に基づき詳細に
説明する。

加熱媒体としては、例えば水が用いられ、加熱媒
体蒸発器１４に貯められている。 The heating medium evaporator 1 is used to supply the heating medium to the LPG evaporator 12 and the gas heater 13.
4 is installed, and a portion of the steam from the power generation boiler is supplied under reduced pressure and used as a heating source. For example, water is used as the heating medium heated by the steam, and is stored in the heating medium evaporator 14.

部分に戻されるよう循環管路となつている。 A steam pipe 15 is connected to the upper steam part of this heating medium evaporator 14, and the steam is sent to the LPG evaporator 12 and gas heater 13, and after being heated or superheated by a drain pipe 16 connected to these steam pipes 15. The condensed steam is returned to the lower water portion of the heating medium evaporator 14 through a circulation pipe.

なつており、常に加熱媒体の蒸気圧力P2がスチ
ーム圧力P1より低くなるようにする。 Depending on the pressure of the vapor of the heating medium heated by steam in the heating medium evaporator 14, there is a possibility that LPG may be mixed into the steam, so a control mechanism is provided to prevent this mixing. A pressure controller 17 is attached to the steam pipe 15, and its detection signal controls the opening of a flow rate regulating valve 18 that regulates the amount of steam flowing in, so that the steam pressure P2 of the heating medium is always maintained. Steam pressure P should be lower than 1 .
例えば、加熱源として送給されるスチームの圧
力P1が５Kg／cm2であるとすれば、加熱媒体蒸発

LPG may get mixed into the heating medium, but steam has a higher pressure than this heating medium, so
The heating medium mixed with LPG will not be mixed into the steam.

据付面積も減少できる。 In addition, since the heating medium is supplied as steam through the steam piping 15, condensed, and then returned through the drain piping 16, natural circulation is possible without the need for a particular circulation pump, and no pump power is required.
The installation area can also be reduced.

It may be determined depending on the conditions of the steam to be supplied.

As specifically explained above with one embodiment, according to this invention, steam is supplied to the heating medium evaporator to turn the heating medium into steam, and the vapor of this heating medium is sent to the LPG evaporator to evaporate LPG. However, since the control mechanism is used to ensure that the pressure of the heating medium steam is always lower than the pressure of the steam that is the heating source, LPG is transferred to the steam through the heating medium.
There is no problem even when using a part of the steam from a power generation boiler where water supply management is strict.
