RMC-00-94 FURNACE RELIABILITY AND OPTIMIZATION THROUGH THE USE OF HIGH EMISSIVITY CERAMIC COATINGS

Description:

The basic design of the refinery production units that will be reviewed in this article requires the firing of a hydrocarbon in the radiant chamber to produce heat. The heat generated is then absorbed by and conducted through the metal process tubing to increase the feedstock’s temperature to the required processing temperature. The operational efficiency of these production furnaces is dependent upon hundreds of factors including feed temperature, production rate, product composition, furnace design, firing rate and the required processing temperature. Additionally, the operational efficiency of these production furnaces is dependent upon: • The ability of the metal process tubing to uniformly absorb and conduct heat to the feedstock being circulated through the process tubing. • The ability of the refractory lining to absorb and re-radiate energy.
