【考案の詳細な説明】 〔産業上の利用分野〕 本考案は，ボイラのダストを含む排ガスにより給水を加
熱する熱交換器のように，固形分を含む熱媒体の通路中
に伝熱管が配置された熱交換器に関する。[Detailed Description of the Invention] [Industrial field of application] In the present invention, a heat transfer tube is arranged in a passage of a heat medium containing solids, such as a heat exchanger for heating feed water with exhaust gas containing dust of a boiler. The heat exchanger which was made.
第３図により従来の熱交換器を示す。 FIG. 3 shows a conventional heat exchanger.
伝熱管パネル01と炉壁02との間には，熱伸びを吸収する

る。これを防ぐため，バッフルプレート04を設けてすき
間への空気流れの集中を防止している。A gap 03 is provided between the heat transfer tube panel 01 and the furnace wall 02 to absorb thermal expansion. However, as much air flows through the gap as it is, the heat transfer tube panel 01 ends at the end. The air flow velocity increases, and erosion wear increases at the ends of the heat transfer tube panel 01 due to powder particles such as fly ash. To prevent this, a baffle plate 04 is provided to prevent the air flow from concentrating in the gap.

ョン摩耗07が生じる。Since the air flow is restricted by the baffle plate 04 arranged upstream of the heat transfer tube panel 01, the baffle plate
The flow velocity partially increases near the tip of 04, and local erosion wear 07 occurs in the pipe forming the heat transfer tube panel 01 located downstream thereof.

熱媒体速度分布ができる。The flow path of the heat medium is divided into the inside of the panel and the gap by the partition plate attached to the side surface of the area of the heat exchanger formed by the heat transfer tube panel group. Further, if the baffle plate for clearance adjustment is used to appropriately narrow the flow path to balance the amount of air flowing in and out of the panel, an average heat medium velocity distribution can be created in the panel.
本考案による実施例を第１図と第２図に示す。 An embodiment according to the present invention is shown in FIGS.
伝熱管パネル１の端部に炉壁２と対向し，かつ，炉壁２

管パネル１の局部的なエロージョン摩耗発生が防止でき
る。The end of the heat transfer tube panel 1 faces the furnace wall 2, and the furnace wall 2
A partition plate 5 is attached with the clearance 3 kept therebetween.
A baffle plate 6 attached to the furnace wall 2 is arranged in the gap 3. The heat medium flowing from the upstream is divided by the partition plate 5 into a flow passing through the heat transfer tube panel 1 and a flow passing through the gap 3. However, since the gap 3 is narrowed by the baffle plate 6, both flows The pressure loss of is equal, the deviation to one side of the air flow does not occur, and the average heat medium velocity distribution is obtained. The velocity of the heat medium has an average velocity distribution, and local erosion wear of the heat transfer tube panel 1 can be prevented from occurring.
伝熱管パネル内を流れる熱媒体速度が均一であるため，
伝熱管パネルの局部的なエロージョンによる偏摩耗の発
生が防止できる。Since the heat medium velocity flowing in the heat transfer tube panel is uniform,
It is possible to prevent uneven wear due to local erosion of the heat transfer tube panel.
