Head Loss Analysis of Thermosyphon Heat Exchanger with Complex Geometry
Authors: , ,
Abstract: The focus of this study is to determine the pressure drop across the two tracts of a system using a thermosyphon type heat-exchanger. For this purpose, experimental studies were carried out on the introduction of the air heater, and various modes (loads) for Thermal Power plants were tested. Experimental studies were conducted at two different fuel bases - coal and natural gas. It was found that the pressure drop on the two tracts is the smallest at the lowest load of the boiler, respectively at the lowest flue gas and fresh air velocity. Experimentally, it was found that the pressure drop on coal fuel for the flue gas tract was 147.15 Pa, and for fresh air - 118.70 Pa. At nominal boiler load, this pressure drop is 205.03 and 247.21 Pa respectively. Experimental studies indicate that the pressure drop in the two tracts of natural gas fuel is about 10-15% higher than that of coal, which is dictated by the specifics of the combustion process. Numerous studies have been carried out, and the results are compared with experimental ones. The error of the numerical solution is not more than 9%, which is within the admissible for this type of research.
