Improving energy efficiency of fired heater by high emissivity coating

All process heaters consume large amounts of fuel to produce the necessary heat that must be transferred to the feed flowing through coils of tubes aligned throughout the heater. Energy costs represent up to 65% of the cost of running a chemical/petrochemical/refining complex. Furnace and heater fuel is the largest component of this cost. In this paper the application of high emissivity coating in fired heaters in order to intensify the heat transfer by radiation and increase the fired energy efficiency was analyzed. The objective is to find out effectiveness of the emissivity coatings on the fuel consumption.
