20.500.12556/RUL-171691 Razvoj napajalnega modula za procesno zaznavalo izločevalnika parnega kondenzata na osnovi termoelektričnega učinka Development of a power supply module for a steam trap process sensor based on thermoelectric effect Izločevalniki parnega kondenzata so ključni za pravilen pretok pare v parnih sistemih, zato je pomembno zagotavljanje njihovega ustreznega delovanja. V diplomskem delu smo obravnavali razvoj napajalnega modula za procesno zaznavalo izločevalnika parnega kondenzata na osnovi termoelektričnega učinka. Napajalni modul je bil napajan preko termoelektričnega generatorja, pri čemer je bil toplotni tok zagotovljen z izkoriščanjem temperaturne razlike med steno cevi za paro in okoliškim zrakom. Eksperimentalno ovrednotenje je pokazalo, da je za ustrezno delovanje potrebna prisilna konvekcija na zračni strani termoelektričnega generatorja, da je zagotovljen dovolj velik toplotni tok in s tem generirani električni tok. Za doseganje ustrezne električne moči je bila potrebna temperaturna razlika vsaj 40 K in temperatura vročega dela nad 140 $ˆ°$C. Ugotavljamo, da je koncept napajalnega modula ustrezen, potrebna pa je nadaljnja optimizacija odvoda toplotena zračni strani in ovrednotenje pri višjih temperaturah na topli strani. Steam traps are crucial for the correct flow rate of steam in steam systems, making it important to ensure their proper operation. In this thesis, we focused on the development of a power supply module for a process sensor of a steam trap based on the thermoelectric effect. The power supply module was powered by a thermoelectric generator, where the heat flow was provided by exploiting the temperature difference between the steam pipe wall and the surrounding air. Experimental evaluation showed that for proper operation, forced convection on the air side of the thermoelectric generator is required, so that a sufficiently large heat flow rate and thus generated electrical power are provided. To achieve adequate electrical power, a temperature difference of at least 40 K and a hot section side temperature above 140 $ˆ°$C were required. We conclude that the concept of the power supply module is appropriate, but further optimization of the heat dissipation on the air side and evaluation at higher temperatures on the hot side are required. izločevalnik parnega kondenzata procesno zaznavalo termoelektrični modul napajalni modul Peltierjev efekt Seebeckov efekt steam trap process sensor thermoelectric generator module power supply module Peltier effect Seebeck effect true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2025-08-30 08:30:35 2025-08-30 08:30:38 2025-09-15 03:31:11 0000-00-00 00:00:00 2025 0 0 XI, 36 f. 2025 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 648.32:536.423.4(043.2) 275034 247488259 43404.pdf 43404.pdf 1 AD216C21184A46384E75BA2BDAA5FB52 4a4da1d46b8d3b0dcd8247eed25f2d55855c735354d1a69eb6c90127bbf77f40 b4413bb4-856a-11f0-9328-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=215073 Fakulteta za strojništvo 0 0 0
