<P>PROBLEM TO BE SOLVED: To provide a boiler system which can prevent a vapor pressure measuring means from being determined to be excessively faulty. <P>SOLUTION: The boiler system includes a failure determining means 42 for determining whether or not a first vapor pressure measuring means 7 is faulty on the basis of a vapor pressure measured by the first vapor pressure measuring means 7 and presence or absence of a signal output from a second vapor pressure measuring means 8. The failure determining means 42 determines that the first vapor pressure measuring means 7 is faulty, when a vapor pressure measured by the first vapor pressure measuring means 7 surpasses a failure upper limit threshold which is higher than an upper limit threshold of a second pressure range of the second vapor pressure measuring means 8 and the presence or absence of the signal output provided from the second vapor pressure measuring means 8 indicates that the vapor pressure falls below the upper limit threshold of the second pressure range, and when the vapor pressure measured by the first vapor pressure measuring means 7 falls below a failure lower limit threshold which is lower than a lower limit threshold of the second pressure range and the presence or absence of the signal output provided from a second vapor pressure measuring means 8 indicates that the vapor pressure surpasses the lower limit threshold of the second pressure range. <P>COPYRIGHT: (C)2013,JPO&INPIT |
