THERMOSYPHON-BASED FLUE GAS CONDENSATION TO IMPROVE THE PERFORMANCE OF DRY-COOLED POWER PLANTS
Аннотация
This study presents the design and simulation of an actively-controlled thermosyphon system for condensing water vapor from the flue gas of natural-gas combined-cycle (NGCC) power plants. The condensed water can be used for sub-ambient evaporative cooling and cool storage to improve the plant's performance. This thermosyphon system consists of polymer heat exchangers acting as a falling film evaporator and metal heat exchangers acting as the air-cooled condenser section. Both cross-flow and axial-flow arrangements are investigated for the flue gas relative to the polymer evaporator tubes. These two flow arrangements are discussed under the design considerations of heat and mass transfer performance.
