Apparatus and method for continuous corrosion monitoring and determination of end point in chemical cleaning process of power plant boilers by hydrogen gas

摘要

The present invention relates to the process of chemical cleaning of power generation and industrial boilers to improve thermal conductivity and to prevent overheating due to scale by dissolving and removing metal oxides attached to the inner surface of boiler tube of power plant. In order to prevent excessive corrosion of the boiler tube by chemical cleaning by continuously monitoring the hydrogen concentration in the chemical cleaning solution by using the principle that occurs, power plant boiler chemical cleaning process monitors the corrosion by using hydrogen gas. An apparatus and method for determining the end point of a washing process are provided.;Boiler, Scale, Chemical Cleaning Process, Hydrogen Gas, Hydrogen Concentration, Corrosion, Endpoint
