<P>PROBLEM TO BE SOLVED: To provide a combustion device with a plurality of easy-to-use burners capable of preventing explosive ignition. <P>SOLUTION: In the combustion device plurally having burners running on gas, when a gas discharge time in a non-combustion state in only one of the burners reaches a first specified value T1, or a total of gas discharge times of the plurality of burners when the plural burners discharge gas at the same time in non-combustion states reaches a second specified value T2, a gas valve is closed. At this point, a relationship between the first specified value T1, the second specified value T2, and the number N of burners having discharged gas at the same time in non-combustion states satisfies the formula T1≤T2, and the formula T1>T2/N at the same time. <P>COPYRIGHT: (C)2012,JPO&INPIT |
