PROBLEM TO BE SOLVED: To suppress fluctuation in steam temperature for a composite boiler system combining a fuel boiler and a solar heat boiler.SOLUTION: In a composite boiler system which comprises by combining a fuel boiler (1) for generating steam by combustion of fuel and a solar heat boiler (200) for generating steam by solar heat, the fuel boiler and the solar heat boiler are connected in parallel to each other. The solar heat boiler is configured by including a heat collecting device (71) for generating steam by heating a fluid flowing inside by condensed sunlight, and a plurality of heliostats (2) for condensing sunlight to the heat collecting device. The heat collecting device is provided at the upper part of a support structure body (100) for supporting the fuel boiler. The composite boiler system is configured in such a manner that a channel for the fluid supplied to the composite boiler system can be switched to a channel which only flows in the fuel boiler and to a channel which flows both in the fuel boiler and in the solar heat boiler. |
