Ztr\u00e1ty spalin: hlavn\u00ed aspekty<\/h3>\n
    \n
  • Mechanismus ztr\u00e1ty<\/strong>:\n
      \n
    • Teplo odch\u00e1z\u00ed s plyny<\/strong>: Spalov\u00e1n\u00edm paliva vznikaj\u00ed spaliny, kter\u00e9 jako hork\u00e9 obsahuj\u00ed zna\u010dn\u00e9 mno\u017estv\u00ed tepeln\u00e9 energie. Pokud se tato energie nestihne p\u0159edat chladic\u00ed kapalin\u011b (vod\u011b, vzduchu atd.), ztr\u00e1c\u00ed se spolu s plyny unikaj\u00edc\u00edmi kom\u00ednem.<\/li>\n
    • Teplota spalin<\/strong>: \u010c\u00edm vy\u0161\u0161\u00ed je teplota spalin, t\u00edm v\u00edce tepla se ztr\u00e1c\u00ed, a t\u00edm vy\u0161\u0161\u00ed je ztr\u00e1ta.<\/li>\n<\/ul>\n<\/li>\n

        \n
      • Sn\u00ed\u017een\u00ed \u00fa\u010dinnosti<\/strong>: Vysok\u00e9 tepeln\u00e9 ztr\u00e1ty se spalinami sni\u017euj\u00ed \u00fa\u010dinnost kotle, co\u017e se projevuje poklesem jeho \u00fa\u010dinnosti.
