The subsequent hot water or steam outlet 4 and steam pipe 5 are connected to other pipes for utilization. When the waste gas temperature is too high, multiple boxes 1 can be connected for cooling, and the boxes 1 at different connections can focus on their purpose of obtaining hot water or steam.

[0022] A connecting box 7 is horizontally arranged on the right side of the box body 1 and is arranged parallel to the box body 1.

The two boxes 1 are connected by the connecting box 7. The temperature of the exhaust gas can be measured by the connecting box 7. The flip cover 8 at the bottom can facilitate the subsequent cleaning of the inside of the connecting box 7.
