In order to predict the furnace heat absorption, which is sensitive to coal properties, an attempt to make a model universally applicable for any kind of pulverized coal fired boiler is in progress. First of all, the heat absorption rates on to furnace wall were surveyed for 600MWe pulverized coal fired boiler, and they were ranked into four levels by indicating a furnace heat absorption index (FHAI). Some ash composition is relatively well related to the FHAI, while a new index from thermomechanical analysis (TMA) offers a good prediction of the furnace heat absorption.
