20.500.12556/DKUM-87136 Application of gas condensing boilers in domestic heating A growing number of households have had condensing boilers built in to be used for the heating of spaces and for the hot water supply. The use of condensing boilers is justified from the point of view of energy because they achieve higher thermal efficiency than traditional boilers. Condensation of water vapour occurs in the flue gases, whereby the heat released by condensation is used to heat the water in the boiler. How much water vapour will condense depends on the temperature to which the flue gases are cooled. In this paper, a thermodynamic analysis of thirteen built-in gas condensing boilers was performed; data on the flue gas composition and temperature, as well as on the excess air required for combustion were obtained for that purpose. The calculation results consisting of the amount of condensed water, the thermal efficiency of the boiler, and the volume flow rates of the air and fuel are presented in tables. The analysis identified the cases in which the water vapour condensation occurred and determined the amount of the condensed water. The cases without water vapour condensation were also identified. gas condensing boilers thermodynamic analysis thermal efficiency of the boiler plinski kondenzacijski kotli termodinamična analiza toplotni izkoristek kotla true false true Faculty of Mechanical Engineering and Naval Architecture Angleški jezik Slovenski jezik Znanstveno delo 2024-02-22 08:51:12 2024-02-22 09:23:30 2024-02-23 03:11:36 0000-00-00 00:00:00 2019 0 0 Str. 681-685 Št. 3 Letn. 26 2019 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2019-06-16 536:697 1024352348 10.17559/TV-20180831125929 1330-3651 Application_of_gas_condensing_boilers_Zivic_2019.pdf Application_of_gas_condensing_boilers_Zivic_2019.pdf 1 C2201E6B16B7B5A26456D03D61AC9447 041b0a4ce7e2db6ef112e805487e445045e76a0c41291f036fc24bd9a164e33f 83e9e36e-d159-11ee-bfea-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=176356 https://doi.org/10.17559/TV-20180831125929 0 86ae5ea9-d15b-11ee-bfea-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=176357 Fakulteta za energetiko 0 0 0
