Combustion device and combustion device system including combustion device

A combustion device included in a plurality of combustion devices used in a combustion device system in which a plurality of combustion control sections of the plurality of combustion devices are communicatively connected to each other via a linkage control section which controls linkage operations of the plurality of combustion devices, and a common exhaust passage can be used for the plurality of combustion devices, the combustion device comprising:

• the combustion control section which controls combustion in the combustion device to which the combustion control section belongs;
• a setting section operated to set information indicating whether or not the plurality of combustion devices are in a common vent discharge state in which the common exhaust passage is used for the plurality of combustion devices;
• and
• a first memory section which stores therein connection configurations between the combustion control section and the other combustion control sections to which the combustion control section is communicatively connected,
• wherein the combustion control section determines whether or not the combustion control section can communicate with the linkage control section or the other combustion control sections, and inhibits combustion in the combustion device to which the combustion control section belongs, in a case where the combustion control section determines that the combustion control section cannot communicate with the linkage control section or at least one of the other combustion control sections and the common vent discharge state is set by the setting section,
• wherein the linkage control section includes:
• an information obtaining section which obtains the information set by the setting section from at least one of the plurality of combustion devices;
• and
• a second memory section which stores therein connection configurations between the linkage control section and the plurality of combustion control sections,
• wherein the linkage control section determines whether or not the linkage control section can communicate with each of the plurality of combustion control sections of the plurality of combustion devices, and sends to the combustion control sections being in communication with the linkage control section, combustion inhibiting commands directing inhibition of combustion in the combustion devices corresponding to the combustion control sections being in communication with the linkage control section, in a case where the linkage control section determines that the linkage control section cannot communicate with at least one of the plurality of combustion control sections and the information obtained from the setting section indicates the common vent discharge state, and
• wherein the combustion control sections being in communication with the linkage control section inhibit the combustion in the combustion devices to which the combustion control sections belong, in response to the combustion inhibiting commands received from the linkage control section.
