Research Project
This research investigates the dynamic performance and economic benefits of using superhydrophobic and slippery liquid infused surfaces fabricated using electrodeposition on condenser tubes in thermoelectric power plants. The non-wetting surfaces enhance performance by deterring fouling, thereby reducing fouling resistance, and promoting dropwise condensation of steam on the shell side. Using a thermal resistance network of a shell and tube condenser, detailed parametric studies are presented to investigate the effect of design parameters—tube diameter, number of tubes—and operating parameters—cooling water velocity, fouling factor and diurnal fluctuations in cooling water temperature—on the annual condenser performance, measured in terms of its electric energy output of a representative 550 MW coal-fired power plant. A cost model is presented to evaluate the technoeconomic benefits of the enhanced condenser designs in a unified manner, in terms of a new levelized cost of condenser (LCOC) metric. The model is coupled with a numerical optimization method to identify optimal non-wetting condenser tube designs that minimize LCOC. Overall, the study presents the first effort to develop enhanced condenser designs with non-wetting tube surfaces on the annual thermoelectric power plant performance, and shows the improvements relative to a baseline condenser design with plain tubes.
