That is, when the first temperature is lower than the preset temperature, the control module controls the temperature to continue to be input into the waste heat transfer chamber 610, and when the temperature is input, the input amount of the superheated gas in each kiln body 100 can be adjusted according to the currently required temperature. When the second temperature is higher than the preset temperature, the control module controls the superheated gas in the waste heat transfer chamber 610 to be input into the heat exchange chamber 500.
