Cocsul sau “c\u0103rbunele ou\u0103”\u00a0 este un soi de c\u0103rbune prelucrat, cel mai probabil ca produs colateral din rafinarea petrolului. <\/p>\n

Vine \u00een forma de oua evident ( \u0103sta pe care l-am cump\u0103rat eu).\u00a0 Industrial Cocsul se g\u0103se\u0219te \u0219i sub alte forme.
\n\u0218i are putere calorifica\u00a0 (c\u0103ldura de ardere ar fi mai corect fizic ) mare. Dublu fa\u021b\u0103 de lemnul uscat.\u00a0 Cca 7800 kcal \/ kg. Asta e app. 9 kwh energie calorica pe kg. De \u00eenmul\u021bit cu randamentul subunitar al cazanului t\u0103u, evident. <\/p>\n

de la\u00a0 Dedeman am luat un sac de 20kg cu 34 de lei. \u0102sta.\u00a0 Asta \u00eenseamn\u0103 1700 lei\/ ton\u0103.\u00a0 E al dracu de scump \u0219i dac\u0103 puterea de ardere ar fi aia trecuta pe sac.\u00a0 Dar de prob\u0103 merge \u00eentruc\u00e2t ma intereseaz\u0103 \u00een c\u00e2t timp se degaj\u0103.\u00a0 adic\u0103 dac\u0103 “ruleaz\u0103”\u00a0 o noapte.<\/p>\n

\u00cen ce central\u0103\u00a0 po\u021bi sa bagi mizeriile \u0103stea?\u00a0 Serios, sunt mizerabili.
\nVezi pe cartea centralei, dac\u0103 po\u021bi sa bagi cocs. Sau combustibil cu puterea asta calorica, sau c\u0103rbune. <\/p>\n

Dac\u0103 ai centrala de o\u021bel cu grosimea de pana \u00een 10 mm, uita de asta. Dac\u0103 o fierbi \u0219i dac\u0103 o \u00eenro\u0219e\u0219ti,\u00a0 ai s-o faci balon. <\/p>\n

—-
\nIndica\u021bia e ca dac\u0103 folose\u0219ti cocs,\u00a0 sau c\u0103rbuni,\u00a0 \u00een general sa faci focul de deasupra, mai ales dac\u0103 aerul intra pe jos \u00een cazan \u0219i iese pe sus. Dac\u0103 aprinzi focul pe jos vor arde to\u021bi c\u0103rbunii odat\u0103 \u0219i e posibil s\u0103 suprasoliciti cazanul <\/p>\n

\"image\"<\/a><\/p>\n

Eu am pus mai \u00eent\u00e2i,\u00a0 de prob\u0103,\u00a0 cca 5-6 kg acoperi\u021bi cu un strat de surcele \u0219i lemne sub\u021biri .
\n\u0218i nu am avut cu ce s\u0103 tai a\u021ba de la sac, a\u0219a c\u0103 am taiat-o cu bricheta.\u00a0 Gen,nu face\u021bi a\u0219a ceva acas\u0103.\u00a0 Serios, nici nu \u021bine\u021bi (a depozita)\u00a0 cocsul \u00een camera centralei. <\/p>\n

\"image\"<\/a><\/p>\n

Focul a \u021binut cca 2h gener\u00e2nd o temperatur\u0103 relativ constant\u0103 a apei \u00een cazan, stabilizandu-se la cca 63 de grade celsius. Bine\u00een\u021beles ca pompa de recirculare merge continuu duc\u00e2nd c\u0103ldura \u00een puffer.<\/p>\n

Dup\u0103 dou\u0103 ore am mai pus 1 lemn \u0219i \u00eenc\u0103 5-6 kg.\u00a0 Tot a\u0219a ard controlat,\u00a0 temperatura \u00een cazan nu sare de 65, iar fum scot, se vede pe co\u0219,\u00a0 dar nu mult \u0219i nu \u00eenec\u0103cios.
\nAm mai pus seara un brat de lemne sa urc temperatura \u00een puffer peste 60 \u0219i asta a fost p\u00e2n\u0103 diminea\u021ba,\u00a0 c\u00e2nd \u00eenc\u0103 mai ardeau 2-3 c\u0103rbuni, dar erau sub masa critica sa mai genereze ori\u0219ice c\u0103ldur\u0103.
\nEu am b\u0103gat asta \u00een Viadrus.
\nDup\u0103 calculele mele trebuia\u00a0 sa scot cca 90kwh *75% randamentul centralei,\u00a0 de\u0219i produc\u0103torul cazanului spune ca e 78% pe c\u0103rbuni.
\n65kwh \u00eenseamn\u0103 ridicarea temperaturii a 1000 litri de apa cu cca 50 grade.
\nEu am rezervor de 500 litri iar pompa la minim circula cca 500 l apa pe ora cu un dteta de aproximativ 15 grade celsius. <\/p>\n

Dup\u0103 dou\u0103 ore am ie\u0219it cu\u00a0 apa ridicata cu 20 de grade ( plus \u00eenc\u0103lzirea calculata mai sus) .\u00a0 Cam jum\u0103tate din ce m-as fi a\u0219teptat.\u00a0 Un pic mai mult ca mai e un boiler de 100 de litri \u0219i\u00a0 a mai urcat \u0219i ala tot cam 20 de grade.
\n\u0218i mai e \u0219i faptul ca \u00eenc\u0103 mai avea jar cocsul dup\u0103 2h dar sc\u0103zuse mult puterea utila \u0219i a trebuit sa suplimentez.<\/p>\n

\u00cen noaptea urm\u0103toare am pus restul, jum\u0103tate de sac.\u00a0 Au ars cca 4 ore activ,\u00a0 men\u021bin\u00e2nd temperatura cazanului intre 67-73 de grade,dup\u0103 care eu m-am b\u0103gat la somn c\u00e2nd temperatura sc\u0103zuse la 61 de grade. Diminea\u021ba mai era \u00eenc\u0103 jar \u0219i temperatura pe cazan era 48 de grade,\u00a0 dar e irelevant pentru ca atunci c\u00e2nd scad sub o masa critica sa se men\u021bin\u0103 unii pe al\u021bii aprin\u0219i c\u0103rbunii de cocs se sting neterminati. <\/p>\n

Prin urmare, concluzionez c\u0103 e mai util sa\u00a0 umpli cazanul cu ei \u0219i s\u0103 arzi o cantitate mare odat\u0103 dec\u00e2t cu taraita. <\/p>\n

Oricum ar fi costa 1.7 lei \/ kg ( la Dedeman).\u00a0 Am g\u0103sit pe olx cu cca 1.2 lei\/ kg.\u00a0 La 1.7 lei\/ kg prime\u0219ti,\u00a0 \u00een teorie max\u00a0 9kwh ( 7800 kcal) .\u00a0 \u00cen practica cu greu po\u021bi exploata final mai mult de 5-6. Pierderi de c\u0103ldur\u0103 prin conducte de cupru, etc.
\nEu nu cred ca am exploatat nici 60% din c\u0103ldura de ardere nominal\u0103.\u00a0 \u0218i nu cred ca au ars ineficient ca ard \u00eencet \u0219i \u00eendelungat,\u00a0\u00a0 nu pierzi mult\u0103 c\u0103ldura pe co\u0219,\u00a0 dar cred ca nu se ridic\u0103 chiar la specifica\u021biile de pe sac.
\nAjungi pe la de 0.4 lei \/kwh, adic\u0103 aproape de pre\u021bul curentului electric la tarif monom ( f\u0103r\u0103 discriminare zi \/ noapte) . <\/p>\n

Dac\u0103 lemnul e cca 370 lei\/ ton\u0103,\u00a0 poate avea\u00a0 chiar \u0219i de 3 ori mai mica puterea calorifica \u0219i tot e mai ieftin,\u00a0 chiar \u0219i verde.\u00a0 \u0218i e \u0219i mai eco, dac\u0103 ii pas\u0103 cuiva \u0219i ar cam trebui c\u0103 fumul ala de-\u021bi iese pe co\u0219 \u00eel respiri \u0219i tu nu numai vecinii tai, chiar dac\u0103 ai cos de 36384956 metri \u00een\u0103l\u021bime. <\/p>\n

Mai am ni\u0219te teste cu porumb de f\u0103cut.\u00a0 Am s\u0103 revin alt\u0103 dat\u0103.<\/p>\n","protected":false},"excerpt":{"rendered":"
