Abstract

In energy-intensive systems, in which energy need to be transported through compact pipelines, steam is very often used as an energy carrier. The latent heat of steam condensation, surpassing its sensible heat, presents a distinctive advantage, resulting in steam pipelines requiring diameters significantly smaller compared to those needed for equivalent thermal power transmission. Nonetheless, the insulation of steam pipelines remains imperfect, resulting in inevitable heat dissipation. Consequently, this thermal loss leads to the condensation of water within the pipelines, necessitating the implementation of steam traps. The precise selection and implementation of suitable steam traps are essential for sustaining optimal pipeline functionality while minimizing energy losses. This research endeavors to comprehensively assess the criteria governing steam trap selection, focusing on their pivotal role in facilitating efficient pipeline operation. To achieve this objective, a mathematical analysis was conducted to quantify the volume of liquid generated within the pipeline due to condensation. Subsequently, an innovative self-regulating steam trap was introduced and evaluated to elucidate its efficiency in evacuating the accumulated liquid. Remarkably, the utilization of these advanced self-regulating steam traps yielded remarkably positive outcomes, profoundly enhancing pipeline performance and obviating steam losses. Through meticulous analysis of the mathematical model and empirical validation of the novel steam trap's functionality, this study not only contributes to enhancing the theoretical understanding of steam pipeline dynamics but also offers practical insights into optimizing their operational efficiency. This research showcases the potential of self-regulating steam traps to revolutionize steam pipeline dewatering practices, ensuring sustained energy transmission with minimal wastage and reaffirming their pivotal role in modern energy systems.
