To prevent corrosion from occurring on a pipe or the like of a steam line or a condensate line easily and effectively in a steam boiler device where water is fed to a steam boiler and heated, steam generated by the heating is used and condensate obtained from the condensation steam is fed to the steam boiler to be mixed with feedwater for reuse.
In a steam boiler device 1, steam sent from a steam boiler 5 is divided, at a steam header 6, into a first steam pipe 40 communicated to a first steam usage device 7 such as a heat exchanger or the like connected to a condensate pipe 41, and a second steam pipe 43 communicated to a second steam usage device 8 such as a steamer that uses the steam itself for food processing. When fatty acid salt is infused into the steam header 6 from an agent infusion device 9, the fatty acid salt is added to the steam, which prevents corrosion from occurring at the pipes 40, 43, and 41.
