摘要： PROBLEM TO BE SOLVED: To provide a corrosion speed estimating method of a boiler heat transfer tube capable of accurately estimating corrosion speed even inferior fuel such as heavy oil, waste tire, RDF, etc., is used.
SOLUTION: In a boiler equipment, a heat exchanger retrieves heat from combustion exhaust gas generated by burning the inferior fuel. The corrosion speed estimating method of the boiler heat transfer tube is for estimating the corrosion speed of the heat transfer tube provided for the heat exchanger in the boiler equipment. In the estimating method, a corrosion main element, which is estimated to be the most influential to corrosion of the heat transfer tube among components of the combustion exhaust gas based on component analysis of the inferior fuel, is identified. A basic estimation formula of the corrosion speed is developed based on correlation between concentration of the corrosion main element and thinning speed of the heat transfer tube. Measurement data, such as thickness of the heat transfer tube, etc., are obtained, a corrosion speed estimation formula is set by correcting the basic estimation formula according to the measurement data, and the corrosion speed of the heat transfer tube is obtained based on the corrosion speed estimation formula.
