PROBLEM TO BE SOLVED: To prevent carbon monoxide or soot in a kiln from being discharged indoors in a large quantity. SOLUTION: This kiln is provided with an exhaust part 36 which discharges combustion gas 50 to the open, an armor 43 which houses a furnace 27, a burner 8, and a blast means 20, and a suction part 46 which discharges the air within this armor 43 to the open. Such a structure can secure the safety by preventing a large quantity of carbon monoxide for reductive burning from being discharged outdoors since the combustion gas is discharged outdoors as suction air 51 even if the combustion gas 50 leaks out from the furnace 27 or the burner 8.
