<P>PROBLEM TO BE SOLVED: To provide a combustion device capable of accurately positioning the hot junction of a thermocouple with respect to a lean flame hole. <P>SOLUTION: The thermocouple 40 is arranged on a mounting plate 7 of the combustion device in parallel with the longitudinal direction of rich-lean burners 9. The thermocouple 40 is supported by a thermocouple support member 20. The thermocouple support member 20 includes a closing portion 24 closing a part of a flame hole portion 70 of the rich-lean burner 9. A recessed portion 31 for exposing the hot junction 45 of the thermocouple 40 to the lean flame hole is provided at a front end of the closing portion 24. Rich flame holes of the rich-lean burners 9 are closed by both side regions of the recessed portion 31. In a plane view of the closing portion 24, the hot junction 45 of the thermocouple 40 is disposed inside of the recessed portion 31. Accordingly, the hot junction 45 of the thermocouple 40 can be accurately positioned with respect to the lean flame hole. <P>COPYRIGHT: (C)2013,JPO&INPIT |
