Tipuri de pelete<\/strong> este o clasificare a pele\u021bilor (granule de combustibil din biomas\u0103) \u00een func\u021bie de materialul surs\u0103 \u0219i de propriet\u0103\u021bile fizice ale acestora. Principala diferen\u021b\u0103 \u00eentre tipurile de pele\u021bi este con\u021binutul lor de cenu\u0219\u0103, adic\u0103 cantitatea de cenu\u0219\u0103 format\u0103 \u00een timpul arderii. Folosit \u00een munc\u0103 cazan pe peleti<\/a>.<\/p>\n

Principalele tipuri de pelete:<\/h3>\n
    \n
  1. Pelete de lemn<\/strong>:\n
      \n
    • Descriere<\/strong>: Fabricat din de\u0219euri de lemn, cum ar fi a\u0219chii, rumegu\u0219 \u0219i praf de lemn. Ele pot fi f\u0103cute dintr-o varietate de lemne, inclusiv copaci de conifere \u0219i foioase.<\/li>\n
    • Con\u021binut de cenu\u0219\u0103<\/strong>: Au de obicei un nivel sc\u0103zut de cenu\u0219\u0103, deoarece lemnul con\u021bine mai pu\u021bine minerale. Con\u021binutul de cenu\u0219\u0103 al unor astfel de pelete este de obicei 0,2\u20130,7% \u00een greutatea combustibilului.<\/li>\n
    • Avantaje<\/strong>: Energie mare de ardere, formare mai mic\u0103 de cenu\u0219\u0103 \u0219i cerin\u021be minime de \u00eentre\u021binere pentru cazane \u0219i sisteme de \u00eenc\u0103lzire.<\/li>\n<\/ul>\n<\/li>\n
    • Pele\u021bi din de\u0219euri agricole<\/strong>:\n
        \n
      • Descriere<\/strong>: Fabricat din reziduuri de cultur\u0103, cum ar fi paie, tulpini de porumb, coji \u0219i alte reziduuri de plante. Acestea sunt a\u0219a-numitele tipuri de pele\u021bi cu con\u021binut ridicat de cenu\u0219\u0103.<\/li>\n
      • Con\u021binut de cenu\u0219\u0103<\/strong>: Au de obicei un con\u021binut de cenu\u0219\u0103 mai mare dec\u00e2t pele\u021bii de lemn, deoarece reziduurile de cultur\u0103 con\u021bin mai multe minerale. Con\u021binutul de cenu\u0219\u0103 al unor astfel de pelete poate ajunge la 1,5\u20133% \u00een greutatea combustibilului.<\/li>\n
      • Avantaje<\/strong>: Utilizarea sporit\u0103 a resurselor locale \u0219i reducerea costurilor cu combustibilul, dar poate necesita \u00eentre\u021binere mai frecvent\u0103 a sistemului de \u00eenc\u0103lzire din cauza volumelor mai mari de cenu\u0219\u0103.<\/li>\n<\/ul>\n<\/li>\n
      • Pelete de turba<\/strong>:\n
          \n
        • Descriere<\/strong>: Fabricat din de\u0219euri de turb\u0103. Ele sunt adesea folosite \u00een regiunile \u00een care turba este o surs\u0103 disponibil\u0103 de combustibil. Turba conduce tipurile de pele\u021bi cu transfer ridicat de c\u0103ldur\u0103.<\/li>\n
        • Con\u021binut de cenu\u0219\u0103<\/strong>: Pele\u021bii de turb\u0103 au un con\u021binut ridicat de cenu\u0219\u0103, deoarece turba con\u021bine o cantitate semnificativ\u0103 de minerale. Con\u021binutul de cenu\u0219\u0103 al unor astfel de pelete poate dep\u0103\u0219i 5% \u00een greutatea combustibilului.<\/li>\n
        • Avantaje<\/strong>: Potrivit pentru regiunile cu rezerve mari de turb\u0103, dar poate necesita cur\u0103\u021barea regulat\u0103 a sistemului de \u00eenc\u0103lzire \u0219i a cazanelor.<\/li>\n<\/ul>\n<\/li>\n
        • Pele\u021bi din extracte \u0219i de\u0219euri din biomas\u0103<\/strong>:\n
            \n
          • Descriere<\/strong>: Fabricat din diverse de\u0219euri de biomas\u0103, cum ar fi extracte de plante, excremente de animale \u0219i alte de\u0219euri organice.<\/li>\n
          • Con\u021binut de cenu\u0219\u0103<\/strong>: Con\u021binutul de cenu\u0219\u0103 poate varia \u00een func\u021bie de materialul surs\u0103, dar, de regul\u0103, astfel de pelete au un con\u021binut de cenu\u0219\u0103 \u00een intervalul 1-2% \u00een greutatea combustibilului.<\/li>\n
          • Avantaje<\/strong>: Folose\u0219te de\u0219euri, ceea ce ajut\u0103 la reducerea costurilor totale de combustibil, dar pot ap\u0103rea probleme cu calitatea constant\u0103 \u0219i cantitatea crescut\u0103 de cenu\u0219\u0103.<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n

            Concluzie:<\/h3>\n

            Tipurile de pele\u021bi sunt luate \u00een considerare la alegerea unui sistem de \u00eenc\u0103lzire, acestea afecteaz\u0103 eficien\u021ba sistemului de \u00eenc\u0103lzire \u0219i frecven\u021ba \u00eentre\u021binerii acestuia. Pele\u021bii de lemn sunt prefera\u021bi pentru ardere mai curat\u0103 \u0219i mai pu\u021bin\u0103 cenu\u0219\u0103, reduc\u00e2nd nevoia de \u00eentre\u021binere frecvent\u0103. Pele\u021bii fabrica\u021bi din de\u0219euri agricole \u0219i turb\u0103 pot fi mai accesibili, dar pot necesita \u00eentre\u021binere mai frecvent\u0103 a sistemului de \u00eenc\u0103lzire datorit\u0103 con\u021binutului lor mai mare de cenu\u0219\u0103.<\/p>","protected":false},"excerpt":{"rendered":"
