Caracteristici de incalzire si instalare la instalarea cazanelor pe peleti FOCUS<\/strong><\/h1>\n

Ast\u0103zi ne vom uita la caracteristicile de \u00eenc\u0103lzire \u0219i de instalare la instalarea cazanelor pe pele\u021bi FOCUS. \u00cen primul r\u00e2nd, observ\u0103m c\u0103 vorbim despre \u00eenc\u0103lzirea automat\u0103 a \u00eenc\u0103perii cu reglare a temperaturii printr-un sistem de climatizare instalat.

De asemenea, echipamentele de \u00eenc\u0103lzire FOCUS sunt destinate deservirii segmentului industrial; cazanele FOCUS pentru gospod\u0103rii apar\u021bin clasei semi-industriale \u0219i se caracterizeaz\u0103 printr-o fiabilitate sporit\u0103.

Se \u0219tie c\u0103 una dintre metodele \u0219i schemele de izolare hidraulic\u0103 este utilizarea unui rezervor tampon izolat sau a unui acumulator de c\u0103ldur\u0103. Caracteristicile de proiectare ale unor astfel de rezervoare sunt diferite, dar principiul general este combinarea <\/span>circuite de schimb de c\u0103ldur\u0103<\/b><\/a>, despre care s-a scris mai devreme.\u00a0<\/span><\/p>\n

Principiul este c\u0103 lichidul de r\u0103cire \u00eenc\u0103lze\u0219te un schimb\u0103tor de c\u0103ldur\u0103 care transport\u0103 un alt lichid de r\u0103cire. Acest lucru se datoreaz\u0103 faptului c\u0103 este necesar s\u0103 se acumuleze c\u0103ldur\u0103 \u00eentr-un volum nereglat, care este generat de cazane sau sobe cu combustibil solid \u00een timpul \u00eenc\u0103rc\u0103rii manuale.

Incalzire si montaj sistem cu cazane pe peleti<\/span><\/h2>\n

Cazanul pe pele\u021bi FOCUS este un cazan pe combustibil solid cu un arz\u0103tor pe pele\u021bi de tip tor\u021b\u0103 instalat \u00een care sunt alimenta\u021bi pele\u021bi; arde cu putere termic\u0103 mare datorit\u0103 tehnologiei de ardere volumetric\u0103.

Partea tehnic\u0103 a problemei<\/span><\/h2>\n

Eficien\u021ba maxim\u0103 a cazanelor cu combustibil solid este atins\u0103 \u00eentr-un interval \u00eengust de temperatur\u0103:<\/span> in regim cald, cand alimentarea este in intervalul 75-85*C, returul este de minim 65*C. Mai mult, acest interval este cel mai eficient din punct de vedere al randamentului, atunci cand ramane foarte putin inainte de zona de fierbere a lichidului de racire.\u00a0<\/span><\/p>\n

Puterea unor astfel de cazane variaz\u0103, dar principalul dezavantaj este zona \u00eengust\u0103 de func\u021bionare stabil\u0103. Ca urmare, apare o problem\u0103 de siguran\u021b\u0103, inclusiv problema binecunoscut\u0103 a stingerii rapide, atunci c\u00e2nd este imposibil s\u0103 \u00eendep\u0103rta\u021bi brusc c\u0103ldura din combustibilul care arde, astfel \u00eenc\u00e2t centrala s\u0103 nu ias\u0103 din intervalul normal de func\u021bionare.\u00a0<\/span><\/p>\n

\u00cen acest caz, se folose\u0219te metoda de \u201edesc\u0103rcare a c\u0103ldurii\u201d \u00een rezervorul tampon. De facto, acumulatorul de c\u0103ldur\u0103 ofer\u0103 nivelul necesar de siguran\u021b\u0103, nu eficien\u021b\u0103. Pute\u021bi, desigur, s\u0103 evita\u021bi problema siguran\u021bei p\u00e2n\u0103 la o oarecare aproximare instal\u00e2nd calorifere din font\u0103 \u0219i \u021bevi metalice rezistente. Economia \u0219i u\u0219urin\u021ba de reglare sunt op\u021biuni pentru func\u021bionarea principal\u0103 a rezervorului tampon.<\/span><\/p>\n

\u00centr-un cazan pe pele\u021bi, aceast\u0103 problem\u0103 este rezolvat\u0103 prin aprindere \u0219i stingere automat\u0103, deci nu este necesar un rezervor tampon.
