[0031] Therefore, in the embodiment, the water body pipeline of the steam pocket assembly 3 can output low-temperature water body to the water body pipeline of the heat exchanger. After the low-temperature water body and the high-temperature coal gas realize heat exchange operation, the low-temperature water body is heated to form high-temperature water body and is superheated to form high-temperature steam. The high-temperature water body and the high-temperature steam are transmitted from the water body-steam pipeline of the heat exchanger to the water body-steam pipeline of the steam pocket assembly 3. In the steam pocket assembly 3, the high-temperature water body reflows into the water chamber and is further output to the heat exchanger, realizing the circulating heat exchange function of the water body. The high-temperature steam is transmitted from the steam pipeline of the steam pocket assembly 3 to the steam pipeline network, realizing the collection and storage function of the high-temperature steam.
