A instala sau nu un rezervor tampon la instalarea unui cazan cu combustibil solid<\/h1>\n

Utilizarea unui \u201ehardtop\u201d conven\u021bional f\u0103r\u0103 arzator pe peleti<\/a> \u0219i f\u0103r\u0103 tampon, este extrem de periculos \u0219i neprofitabil din punct de vedere economic, deoarece \u00een modul de ardere mocnit, eficien\u021ba unui combustibil solid scade rapid, iar acest lucru este valabil mai ales pentru cazanele cu post-ardere a produselor de ardere!<\/h4>\n

Lua\u021bi \u00een considerare caracteristicile \u201etopurilor solide\u201d<\/h2>\n

Tot cazane pe combustibil solid<\/a>, indiferent de tipul \u0219i metoda lor de ardere a combustibilului, au urm\u0103toarele caracteristici comune:<\/strong><\/h4>\n
    \n
  1. Ele func\u021bioneaz\u0103 numai \u00eentr-un program \u00eengust de temperatur\u0103 ridicat\u0103 (90\/75 0\u0421 sau 80\/600\u0421).<\/li>\n
  2. Ele pot modifica puterea \u00een intervalul 100\u202650% prin reducerea cantit\u0103\u021bii de aer care intr\u0103 \u00een timpul arderii. Mai mult, cu o sc\u0103dere a puterii, eficien\u021ba scade brusc din cauza cre\u0219terii propor\u021biei de CO.<\/li>\n
  3. Centrala nu poate fi oprit\u0103 p\u00e2n\u0103 c\u00e2nd tot combustibilul din el nu s-a ars.<\/li>\n
  4. Un cazan \u00eenc\u0103rcat manual este selectat cu o rezerv\u0103 de putere de cel pu\u021bin 30% pentru cea mai rece perioad\u0103 de cinci zile pentru spa\u021biile reziden\u021biale \u0219i p\u00e2n\u0103 la 50% pentru cl\u0103dirile de birouri, deoarece poate ap\u0103rea o problem\u0103 semnificativ\u0103 cu calitatea \u0219i umiditatea combustibilului, care trebuie s\u0103 fie luat in considerare.<\/li>\n<\/ol>\n
    Sistemele moderne de \u00eenc\u0103lzire, \u00een func\u021bie de temperatura exterioar\u0103 \u0219i de clima interioar\u0103, modific\u0103 debitul \u0219i temperatura \u00een dispozitivele de \u00eenc\u0103lzire. Astfel, la instalarea unui cazan cu combustibil solid \u00eentr-un sistem de \u00eenc\u0103lzire, apare o dilem\u0103: cazanul func\u021bioneaz\u0103 cel mai economic \u00een modul de temperatur\u0103 ridicat\u0103, iar sistemul de \u00eenc\u0103lzire \u00een modul de temperatur\u0103 sc\u0103zut\u0103.<\/div>\n
    Capacitatea tampon rezolv\u0103 aceast\u0103 dilem\u0103. Acesta permite cazanului cu combustibil solid s\u0103 ard\u0103 combustibil cu eficien\u021b\u0103 maxim\u0103 \u0219i s\u0103 \u00eel depoziteze \u00eentr-un rezervor tampon cu pierderi mici. Iar sistemul de incalzire ia caldura acumulata in portiuni clar calculate in functie de necesitatea acesteia si in functie de pierderile de caldura ale cladirii.<\/div>\n
    De asemenea, s-a observat c\u0103 sistemele cu cazane cu combustibil solid care nu au capacitate tampon au un consum de combustibil de 2-2,5 ori mai mare dec\u00e2t sistemele cu capacitate tampon. Acest lucru se datoreaz\u0103 faptului c\u0103 de cele mai multe ori \u00een timpul sezonului de \u00eenc\u0103lzire, vremea este relativ cald\u0103, ceea ce \u00eenseamn\u0103 c\u0103 cazanul func\u021bioneaz\u0103 \u00een mod constant cu o lips\u0103 de aer de ardere \u0219i mai mult de jum\u0103tate din combustibil zboar\u0103 literalmente \u00een \u021beav\u0103 din form\u0103 de CO (undercooking).<\/div>\n

    Cea mai mare eficien\u021b\u0103 \u00een cazan cu combustibil solid<\/a> in momentul in care este peste punctul de roua de retur (de obicei 51 de grade), dar inca nu a atins temperatura setata pe regulator! De \u00eendat\u0103 ce cazanul cu combustibil solid atinge temperatura setat\u0103 \u0219i intr\u0103 \u00een mocnit, eficien\u021ba cazanului scade la 20%, compens\u00e2nd astfel toate economiile.<\/p><\/blockquote>\n

    Pe l\u00e2ng\u0103 economisirea de combustibil, rezervorul tampon v\u0103 permite s\u0103 reduce\u021bi semnificativ num\u0103rul de \u00eenc\u0103rc\u0103ri de combustibil \u00een timpul zilei. Volumul estimat al rezervorului depinde de puterea cazanului, sarcina de combustibil \u0219i timpul de ardere pe sarcin\u0103 \u0219i de ceea ce dori\u021bi de la rezervorul tampon (acumularea de energie neutilizat\u0103). Se recomand\u0103 de la minim 25 de litri (acest volum este de obicei setat pentru a proteja \u00eempotriva fierberii \u0219i nu poate acumula corect energie \u00een volum suficient) p\u00e2n\u0103 la optim 55 litri per kW puterea cazanului.<\/strong><\/div>\n
    \n

    \u0218i drept urmare, ob\u021binem o central\u0103 automat\u0103 pe pele\u021bi mult mai ieftin\u0103 dec\u00e2t o central\u0103 cu \u00eenc\u0103rcare manual\u0103 a combustibilului, oric\u00e2t de paradoxal ar suna, at\u00e2t la costul echipamentelor, c\u00e2t \u0219i la pre\u021bul combustibilului, care este de obicei mai mic dec\u00e2t costul. de munca de la focari!<\/p><\/blockquote>\n<\/div>\n<\/div>\n
