<p><P>PROBLEM TO BE SOLVED: To prevent abnormal combustion and to quickly and easily specify a fault cause such as defective ignition. <P>SOLUTION: A detection box (flood detection box 58) sets a detection level (Lf) on the basis of the height of an ignition part (166) of a combustion part (reheating burner 80) for combusting fuel, enters and stores water (63) arriving at the detection level or more and includes electrodes (electrodes 60, 62) to be conducted through the stored water. An ignition circuit (65) for igniting supplied fuel is connected to the combustion part and an on-off valve (reheating electromagnetic valve 50) for opening and closing a fuel supply passage for supplying the fuel to the combustion part is attached to the fuel supply passage. When the electrodes of the control box are conducted, a control means (control part 56, microcomputer 168) stops a function of the ignition circuit and closes the on-off valve. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
