Abstract
To prevent steam side oxide spalling and blocking in high temperature heating surface tubes
optimization on the ARMITT prediction model was conducted to determine the key parameters and design model for predicting the oxide spalling
on the basis of in-depth analysis on reasons of oxide spalling.Based on this
the B/S structure based boiler tube inner oxide spalling risk warning system was developed and applied in several power plants.The application showed that
the system warning results basically agreed with the inspection result on site.This system can be used for boilers with large oxide spalling tendency
warn the high risk area of boiler tube and ensure the safe operation of the unit.
