ABSTRACT:
In a method of measuring heat flux and corrosion in a furnace, pairs of thermocouples are attached to the back side of the furnace wall. One thermocouple of each pair is attached to a tube and the second thermocouple is attached to a web connected to that tube. A temperature differential is determined for each pair at selected time intervals. A decrease in the difference between temperature differentials indicates slag on the furnace wall has melted indicating corrosion can be occurring.
