摘要： A scale inhibition method for injecting an alkaline agent and a chelating agent into a fluid containing at least silica and calcium ions, and inhibiting generation of scale, includes feeding the chelating agent and the alkaline agent into piping channeling the fluid, mixing the fluid while causing the fluid to flow in a chemical-mixing part provided in the piping, and when either a pressure difference between the pressures or a flow rate difference between the rates of fluid flow at an inlet and an outlet of the chemical-mixing part exceeds a preset upper threshold, increasing the amount of the chelating agent fed, and feeding the chelating agent at an increased feed amount until the pressure difference or flow rate difference falls below a preset lower threshold.
