PROBLEM TO BE SOLVED: To appropriately control an injection rate of a condensate treatment agent or boiler compounds so as to prevent pipe corrosion.SOLUTION: A chemical feed system provided with a chemical feed means 4 for injecting a condensate treatment agent or boiler compounds into the drain water generated from load equipment 3 that uses steam supplied from a steam supply source 2 includes: drain flow rate measurement means 5A and 5B that measure a flow rate of the drain water discharged from the load equipment 3 and calculate an integrated value; and a chemical feed amount calculation means 5E for calculating the chemical feed amount of the chemical feed means 4 based on the integrated value of the flow rate of the drain water calculated by the drain flow rate measurement means 5A and 5B. |
