Abstract: PURPOSE:To prevent a temperature sensor from being incapable of detection due to choking with air and to enable a steam generating can body to be reliably full of water at all times, by a method wherein during an initial operation mode, an ON- OFF valve is forcibly opened during combustion by a burner to discharge air in the steam generating can body, a subtank and a pipeline by which the can body and subtank are interconnected. CONSTITUTION:During combustion by a burner 12 in an initial operation mode in which the interior of a steam generating can body 11 is brought into a full-of-water state during the starting of operation once, by forcibly opening an ON-OFF valve 19, steam generated in the steam generating can body 11 is circulated through a bypass pipe 25, an auxiliary tank 14, and a water feed pipe 15 by means of a conveyance pipe 13. During the circulation, air remaining in the steam generating can body 11 is discharged through the conveyance pipe 13 to the ejector 20 side as air is circulated together with steam. Thus, by a subsequent stop of combustion once, a pressure in the auxiliary tank 14 and the steam generating can body 14 is sufficiently reduced, and water from a water storage tank 21 is returned so that the auxiliary tank 14 and the steam generating can body 11 are full of water. During a subsequent operation mode, a trouble in which the detection of a temperature sensor 33 is disturbed because of the water feed pipe 15 being choked with air can be also prevented from occurring.
