Description
【考案の詳細な説明】
本考案はボイラー等の排気熱が流通するダクト内に配置
して上記排気熱を回収する熱回収用熱交換器に関し、特
に熱交換器内を循環するブラインは排気熱によって沸騰
する水等を使用するものに好適な熱交換器に係る。[Detailed description of the invention] The present invention relates to a heat recovery heat exchanger that is placed in a duct through which exhaust heat from a boiler or the like flows and recovers the exhaust heat. The present invention relates to a heat exchanger suitable for use with water that is boiled by water.
この種の熱交換器において、排気熱が高温の場合運転開
始時ならびに運転時、ブライン流通管内でブラインが沸
騰し、蒸気が発生する。In this type of heat exchanger, when the exhaust heat is high temperature, the brine boils in the brine flow pipe and steam is generated at the start of operation and during operation.
その結果ブラインが流れにくくなって流通管内に高圧力
を与えたり、ブラインの流れを阻止して熱交換率を悪く
するといった欠点を有していた。As a result, the brine becomes difficult to flow, creating a high pressure inside the flow pipe, and the flow of the brine is blocked, resulting in poor heat exchange efficiency.
本考案は上記した状態にあっても円滑に発生蒸気を出口
側に導くとともに、熱交換率の高い熱交換器を提供する
ことを目的として成されたものである。The present invention has been made with the object of providing a heat exchanger that smoothly guides generated steam to the outlet side even under the above-mentioned conditions and has a high heat exchange efficiency.

Since ・ is located at a high position, it can escape smoothly to the piping 10 and tank 9.
寸た排熱の流れる方向と水との流れが対向流となるため
、熱回収効率が極めて良くなるものである。Since the flow direction of the small amount of waste heat and the flow of water are opposite to each other, the heat recovery efficiency is extremely improved.

のズ」向流によって熱回収効率がすこぶる向上するもの
である。As is clear from the explanation on the ground, the heat exchanger for heat recovery devised by Wood consists of a large number of plate fins arranged side by side, through which brine flow pipes such as water, which are closed on one side and open on the other, are installed orthogonally. An inlet header and an outlet header are provided at the open ends of the flow pipes, and the flow pipes connected to the outlet headers are aligned with the exhaust heat air path and positioned on the windward side,
Since this distribution pipe is arranged at a higher level than the distribution pipe connected to the inlet header, even if the brine boils in the distribution pipe due to the exhaust heat from the exhaust heat air path, the steam will flow smoothly. The heat recovery efficiency is greatly improved by the countercurrent flow between the waste heat and the brine, without causing any adverse effects within the pipeline due to the exhaust gas reaching the exit side.
