Reducing Temperature of Heat Transferring Wall by Intensifying Heat Transfer During Heating of Viscous Liquids

RESEARCH, DESIGN, CALCULATIONS, AND OPERATING EXPERIENCE PROCESSES AND EQUIPMENT FOR CHEMICAL AND OIL-GAS PRODUCTION

The possibilities of reducing the temperature of the heat transferring wall by intensifying heat transfer in productive tubes of viscous liquid heaters to reduce the risk of tube coking are analyzed. A generalized relationship linking thermal and hydraulic properties of flows at low Reynolds numbers is derived for heat transfer intensifiers in the form of wire spirals and twisted tapes inserted into the tubes. It is shown that the design specifications of the heat transfer intensifiers, which ensure the desired level of heat-transferring wall temperature reduction, can be determined by the derived relationship.
