When the heat storage temperature of the temperature sensing device 4 is higher or lower than the set range, the main controller will sound an alarm to remind the staff to perform inspection and maintenance. In this embodiment, the exhaust gas enters the combustion chamber body 1 from the air inlet 9, enters the combustion chamber 2 through the heat storage part 3, and is ignited by the burner to decompose into water, carbon dioxide and other gases, while generating a large amount of heat. After the heat is stored in the heat storage part 3, it is discharged from the air outlet.
