PROBLEM TO BE SOLVED: To use a corrosion inhibitor without waste for suppressing corrosion of steam piping and condensation piping of a steam boiler device, and stably operating the steam boiler device. SOLUTION: The steam boiler device is provided with a steam boiler 3 generating steam by heating feed water, a load device 4 using the steam, the steam piping 5 for feeding the steam to the load device 4, the condensate piping 6 for recovering condensed water obtained by condensing the steam used in the load device 4 and mixing it with the feed water, and an injecting part 7 for injecting a necessary amount of the corrosion inhibitor comprising morpholine fatty acid salt into either one or both of the steam piping 5 and the condensate piping 6. The injecting part 7 is set so that the necessary amount can be adjusted in response to an amount of steam generated by the steam boiler 3. COPYRIGHT: (C)2004,JPO
