Abstract
Aiming at solving the problem of overheating and tube bursting caused by oxide scale peeling and stacking of high temperature heating surface tubes in thermal power plants for a long time
an on-line detection method for oxide scale particles was proposed and an online monitoring device was developed. Through analysis on relevant data obtained via actual online monitoring
it finds that there is a certain correspondence between data changes and unit operation. The result provides a new method and idea for the next step of on-line monitoring technology for heated surface oxide scale accumulation.
