Description

本発明は、二重管熱交換器を備えたボイラの温水供給システムに関し、さらに詳細には、温水供給が中断される環境下で、温水経路用外管と加熱水経路用内管が設置されている二重管熱交換器を有するボイラ内で正常に加熱動作を行うことができる、二重管熱交換器を備えたボイラの温水供給システムに関する。   The present invention relates to a hot water supply system for a boiler equipped with a double-pipe heat exchanger, and more particularly, an outer pipe for a hot water path and an inner pipe for a heated water path are installed in an environment where the hot water supply is interrupted. The present invention relates to a hot water supply system for a boiler equipped with a double-tube heat exchanger that can normally perform a heating operation in a boiler having a double-tube heat exchanger.

周知のように、家庭や公共の建物において、室内を暖房し温水を供給するためボイラは使用されてきた。一般に、ボイラは、二重管熱交換器または単一管熱交換器を使用する。   As is well known, boilers have been used in homes and public buildings to heat indoors and supply hot water. Generally, boilers use a double tube heat exchanger or a single tube heat exchanger.

一般に、二重管熱交換器とは、燃焼熱を直接伝達するため、温水経路および加熱水経路を有する二重管が燃焼室内に配置されたものを意味する。単一管熱交換器とは、燃焼熱を間接的に伝達するため、温水熱交換器が燃焼室から分離されているものを意味する。   In general, a double pipe heat exchanger means that a double pipe having a hot water path and a heated water path is arranged in a combustion chamber in order to directly transfer the heat of combustion. A single tube heat exchanger means that the hot water heat exchanger is separated from the combustion chamber to indirectly transfer the heat of combustion.

図１は、温水経路として外管が使用された二重管熱交換器を備えたボイラの通常の温水供給システムの構成を示す図である。   FIG. 1 is a diagram illustrating a configuration of a normal hot water supply system of a boiler including a double-tube heat exchanger in which an outer pipe is used as a hot water path.

通常のボイラにおいて、バーナー２０は、燃焼室１０の下部に配置されている。熱交換器３０は、バーナー２０の上部に設置されている。従って、バーナー２０から生成された熱エネルギーは、水が通常流れる管を含む熱交換器３０に伝達される。   In a normal boiler, the burner 20 is disposed in the lower part of the combustion chamber 10. The heat exchanger 30 is installed on the upper part of the burner 20. Accordingly, the thermal energy generated from the burner 20 is transferred to the heat exchanger 30 that includes a tube through which water normally flows.

本明細書に添付の図１に示すように、通常の二重管熱交換器には、加熱水経路に使用される外管３１、および温水経路に使用される内管３２が含まれる。通常の二重管熱交換器において、燃焼熱は最初にバーナー２０から外管３１に伝達され、その後、内管３２に伝達される。   As shown in FIG. 1 attached to the present specification, a typical double pipe heat exchanger includes an outer pipe 31 used for a heating water path and an inner pipe 32 used for a hot water path. In a normal double tube heat exchanger, combustion heat is first transferred from the burner 20 to the outer tube 31 and then transferred to the inner tube 32.

二重管熱交換器を有する通常のボイラにおいて、加熱水循環装置は、熱交換器３０の内管３２、加熱水供給管５１、加熱水ライン５０、第１の戻り水管５２、膨張タンク５３、第２の戻り水管５４、循環ポンプ４０、および第３の循環管５５が順次互いに接続されている構造を有する。   In a normal boiler having a double pipe heat exchanger, the heating water circulation device includes an inner pipe 32 of the heat exchanger 30, a heating water supply pipe 51, a heating water line 50, a first return water pipe 52, an expansion tank 53, a first tank. The second return water pipe 54, the circulation pump 40, and the third circulation pipe 55 are sequentially connected to each other.

従って室内暖房動作の間、加熱水は、循環ポンプ４０によって熱交換器３０の内管３２の中を流れ、燃焼室２０内で生成された熱エネルギーは、加熱水の流れによって加熱水ライン５０に伝達される。   Accordingly, during the indoor heating operation, the heating water flows through the inner pipe 32 of the heat exchanger 30 by the circulation pump 40, and the heat energy generated in the combustion chamber 20 is supplied to the heating water line 50 by the flow of the heating water. Communicated.

他方で、水供給システムには、熱交換器の外管３１に水を供給するため、冷水管６１、熱交換器３０の外管３１、および加熱された水を外管３１から出すための温水管６１が含まれ、これらは順次互いに接続されている。   On the other hand, in the water supply system, in order to supply water to the outer tube 31 of the heat exchanger, the cold water tube 61, the outer tube 31 of the heat exchanger 30, and hot water for taking out the heated water from the outer tube 31. Tubes 61 are included and are sequentially connected to each other.

従って、水供給管（図示せず）から導入された水は、熱交換器３０を経由して外管３１に流れ、熱交換器３０内で燃焼熱によって加熱された外管３１の温水は、温水管６２から外部に出される。   Therefore, the water introduced from the water supply pipe (not shown) flows to the outer pipe 31 via the heat exchanger 30, and the hot water in the outer pipe 31 heated by the combustion heat in the heat exchanger 30 is It is taken out from the hot water pipe 62 to the outside.

しかし、水供給管からの水の供給が一時的に中断すると、熱交換器３０の外管３１内の水は、冷水管６１から出される。その結果、熱交換は、外管３１と内管３２との間で熱伝達媒体である水が不足するため、室内暖房の機能が異常となる。さらに、熱交換器３０が過熱して損傷し得るという課題がある。   However, when the supply of water from the water supply pipe is temporarily interrupted, the water in the outer pipe 31 of the heat exchanger 30 is discharged from the cold water pipe 61. As a result, in the heat exchange, water serving as a heat transfer medium is insufficient between the outer tube 31 and the inner tube 32, so that the function of indoor heating becomes abnormal. Furthermore, there is a problem that the heat exchanger 30 may be overheated and damaged.

従って本発明は、先行技術で生じる上述の課題を解決するためになされ、水供給が中断する状況下で、温水経路に使用される外管および加熱水経路に使用される内管が設置された二重管熱交換器を有するボイラ内で暖房動作を通常行う、二重管熱交換器を備えたボイラの温水供給システムを提供することが本発明の目的である。   Accordingly, the present invention has been made to solve the above-mentioned problems occurring in the prior art, and in a situation where water supply is interrupted, an outer pipe used for the hot water path and an inner pipe used for the heated water path are installed. It is an object of the present invention to provide a hot water supply system for a boiler equipped with a double pipe heat exchanger that normally performs a heating operation in a boiler having a double pipe heat exchanger.

本発明の目的を達成するため、燃焼熱が燃焼室のバーナーから直接伝達される外管を含む二重管熱交換器と、熱交換器の外管に水を供給するための冷水管と、熱交換器の外管から水が出される温水供給管と、を含み、逆流遮断弁および圧力吸収器が冷水管に設置されている、ボイラの温水供給システムが提供される。
有利な効果 In order to achieve the object of the present invention, a double pipe heat exchanger including an outer pipe in which combustion heat is directly transmitted from a burner of a combustion chamber, a cold water pipe for supplying water to the outer pipe of the heat exchanger, There is provided a hot water supply system for a boiler, including a hot water supply pipe through which water is discharged from an outer pipe of the heat exchanger, and wherein a backflow shut-off valve and a pressure absorber are installed in the cold water pipe.
Advantageous effect

上述のように、本発明に従った二重管熱交換器を備えたボイラの温水供給システムには、逆流遮断弁および圧力吸収器が含まれ、それにより、水供給が中断している状況下で室内暖房の動作を行い、ボイラの過熱によって生じる熱交換器の損傷を抑止することでボイラの寿命を延ばす。   As mentioned above, a hot water supply system for a boiler equipped with a double-tube heat exchanger according to the present invention includes a backflow shutoff valve and a pressure absorber so that the water supply is interrupted. The operation of the room heating is performed at, and the life of the boiler is extended by suppressing damage to the heat exchanger caused by overheating of the boiler.

以下、本発明の好適な実施形態を添付の図面を参照して詳細に記載する。   Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

図２は、本発明の実施形態に従った、二重管熱交換器を備えたボイラの温水供給システムの構成を示す図である。   FIG. 2 is a diagram showing a configuration of a hot water supply system for a boiler having a double-tube heat exchanger according to an embodiment of the present invention.

本発明に従った、冷水管６１、熱交換器の外管３１、温水管６２は、通常の管と同一の構造を有する。従って、管の詳細な説明は重複した記載を避けるため省略する。温水供給システムに新たに加わった構造的部材の動作を詳細に記載する。   The cold water pipe 61, the outer pipe 31 of the heat exchanger, and the hot water pipe 62 according to the present invention have the same structure as a normal pipe. Therefore, a detailed description of the tube is omitted to avoid redundant description. The operation of the structural member newly added to the hot water supply system will be described in detail.

本明細書に添付の図２に記載のように、本発明に従った二重管熱交換器を備えたボイラの温水供給システムには、冷水管６１に設置された逆止弁７０、および逆止弁７０と熱交換器３０との間の冷水管６１に設置された圧力吸収器８０が含まれる。   As shown in FIG. 2 attached to the present specification, a hot water supply system for a boiler having a double pipe heat exchanger according to the present invention includes a check valve 70 installed in a cold water pipe 61, and a check valve. A pressure absorber 80 installed in the cold water pipe 61 between the stop valve 70 and the heat exchanger 30 is included.

逆止弁７０は、図３に示すように、正常動作の場合、水供給管から熱交換器３０へ冷水が流れることを可能とすることで、水供給を中断しないようにしている。さらに、水供給が中断した場合は、逆止弁７０は、熱交換器３０の外管３１の水が出されることを防ぐ。   As shown in FIG. 3, the check valve 70 prevents the water supply from being interrupted by allowing cold water to flow from the water supply pipe to the heat exchanger 30 in the normal operation. Furthermore, when water supply is interrupted, the check valve 70 prevents water from the outer pipe 31 of the heat exchanger 30 from being discharged.

圧力吸収器８０は、図３に示すように、水供給が正常に行われているときは動作しない。しかし、水供給が中断しているとき、逆止弁７０によって水の流れが中断されている状態で、圧力吸収器８０は、加熱される熱交換器の外管内の水の膨張によって生じた増加圧力のバッファとして機能する。   As shown in FIG. 3, the pressure absorber 80 does not operate when the water supply is normally performed. However, when the water supply is interrupted, with the check valve 70 interrupting the flow of water, the pressure absorber 80 increases due to the expansion of the water in the outer tube of the heat exchanger being heated. Acts as a pressure buffer.

図３に示すように、逆止弁７０による熱交換器の圧力の増加を防ぐため、圧力吸収器８０は、膨張した温水の容量に対応する空間を提供する。その結果、熱交換器の内部圧力の増加によって生じる熱交換器の損傷を抑止することが可能である。   As shown in FIG. 3, in order to prevent an increase in the pressure of the heat exchanger by the check valve 70, the pressure absorber 80 provides a space corresponding to the capacity of the expanded hot water. As a result, it is possible to suppress damage to the heat exchanger caused by an increase in the internal pressure of the heat exchanger.

上述のように、本発明は、水供給が中断している状況下で、室内暖房の動作を正常に行う、温水経路に使用される内管を含む二重管熱交換器を備えたボイラを提供する。   As described above, the present invention provides a boiler having a double-tube heat exchanger including an inner pipe used for a hot water path, which normally performs indoor heating operation under a situation where water supply is interrupted. provide.

本発明の好適な実施形態を説明する目的で記載してきたが、当業者は、添付の特許請求の範囲に開示された発明の範囲と精神から逸脱することなく、多様な改変、追加、および置換が可能であることを理解するであろう。   Although preferred embodiments of the present invention have been described for purposes of illustration, various modifications, additions and substitutions will occur to those skilled in the art without departing from the scope and spirit of the invention as disclosed in the appended claims.
