本発明は蓄熱熱交換器に係シ、とくに燃焼ガスを用いて
高温ガスを得るに適する蓄熱熱交換器に関する。DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a regenerative heat exchanger, and particularly to a regenerative heat exchanger suitable for obtaining high-temperature gas using combustion gas.

熱損失を減少させる。As shown in Fig. 1(a), the heat storage heat exchanger passes heating gas and heated gas alternately through the pebble heat storage body 3, and transfers the heat absorbed by the pebble heat storage body during the heating period to the heated gas during the cooling period. It dissipates heat. The pebble heat storage body 3 is supported by a support plate 2. Further, the outer periphery of the support plate 2 is fixed with a heat insulating material 1, and the heat insulating material 1 reduces heat loss from the heating gas, the gas to be heated, and the heat storage body.

。Traditionally, pebble heat storage heat exchangers have the following drawbacks: Because there is heat loss from the insulation material 1 around the heat storage body,
A radial temperature distribution occurs in the heat storage body, and in particular a large temperature difference occurs between the insulation material and the heat storage body. Also, Figure 1 (
As you can see from bl, a large space is created between the insulation material 1 and the pebble heat storage material 3, and this creates a space between the pebble heat storage material 3 and the pebble heat storage material 1.
A large amount of gas flows between them because the flow path resistance is smaller than that of the center of the pebble heat storage element. For these purposes, if the heated gas is poured from the bottom of the heat storage heat exchanger, a large amount of low temperature gas between the insulation material and the pebble heat storage body will flow, and the high temperature heated gas in the center of the pebble heat storage body will be mixed with the average heated gas. The temperature drops slightly.
本発明は上記欠点を解決するためになされたもので、蓄
熱熱交換器出口の被加熱ガス平均温度を上昇することを
目的とする蓄熱熱交換器でおる。The present invention has been made to solve the above-mentioned drawbacks, and is a regenerative heat exchanger whose purpose is to increase the average temperature of the heated gas at the outlet of the regenerative heat exchanger.
本発明は蓄熱体と断熱材空間に小さな補助ペブル蓄熱体
を充填することによって流路抵抗を増してペブル蓄熱体
と断熱材間の流量を減少させる蓄熱熱交換器である。The present invention is a thermal storage heat exchanger that increases flow path resistance and reduces the flow rate between the pebble heat storage body and the heat insulation material by filling the space between the heat storage body and the heat insulation material with small auxiliary pebble heat storage bodies.

熱体と断熱材間の低温ガス流量が減少することによって
被加熱ガス平均温度を上昇ぜせる。According to the present invention, when the heated gas is poured, the average temperature of the heated gas is increased by reducing the flow rate of the low temperature gas between the pebble heat storage body and the heat insulating material.

３の間に充填されてペブル蓄熱体を構成してゆく。The auxiliary pebble heat storage body 4, which plays the role of increasing the flow resistance between the pebble heat storage body 3 and the heat insulating material 1, is filled between the heat insulating material 1 and the pebble heat storage body 3 while the pebble heat storage bodies 3 are stacked one by one. This will form a pebble heat storage body.
