Vpliv netesnosti kotlovskih naprav na njihovo učinkovitost = The influence of air leakage on the efficiency of boilersDrobnič, Boštjan ; Senegačnik, Andrej ; Oman, Janez, 1947-2011Izkoristek pretvorbe toplote v mehansko delo je zelo pomemben parameter toplotnih strojev, zato moramo skrbeti , da se tudi primarno spreminjanje notranje energije goriva v toploto izvede s čim ... boljšim izkoristkom. Pri parnih kotlih se s predgrevanjem zgorevalnega zraka v grelnikih zraka del iztopajoče nizkotemperaturne toplote dimnih plinov ponovno vrača v zgorevalni proces, s čimer se zveča izkoristek kotla. Grelniki zraka so pri večjih postrojenjih običajno Ljungstörmovi rotacijski regeneratorji, katerih značilnost je določena netesnost in mešanje tokov zraka in dimnih plinov. Prispevek se ukvarja z vplivom netesnosti grelnika zraka in vplivom količine zgorevalnega zraka, ki se segreva v grelniku zraka, na izkoristek kotlovskega postrojenja. Raziskane so značilne vrste netesnosti na grelniku zraka in na samem kotlu. Teoretična razlaga je podprta z rezultati meritev na termoelektrarniških grelnikih zraka.Source: Strojniški vestnik = Journal of mechanical engineering. - ISSN 0039-2480 (Letn. 45, št. 2, 1999, str. 75-84)Type of material - article, component partPublish date - 1999Language - slovenian, englishCOBISS.SI-ID - 3044379
