Method for Evaluating Additives Useful for Improving the Efficiency of Heat Transfer in a Furnace and Systems for Performing Same

摘要

Additives for improving furnace heat transfer efficiency may be effectively screened for effectiveness by heating the additive, optionally mixed with ash, to the operating temperature of the furnace and measuring its relative emissivity. Additives that have lower emissivity at furnace operating temperatures may be useful for improving furnace heat transfer efficiency as compared to those that have higher emissivity.
