Ziwotche za biomass komanso kutsutsana kwamalingaliro a CO2

nkhuni

Mu post yapita tidakambirana mphamvu zotsalira zazomera . Kuchokera pazomwe zili, momwe zimagwirira ntchito komanso komwe zimachokera kuzabwino ndi zovuta zake. Ndatchulapo pang'ono za zotentha za biomass, koma sindinafotokoze mwatsatanetsatane popeza ndikufuna kuwulula apa mwatsatanetsatane.

Mu positi iyi tikambirana ma boilers osiyanasiyana a biomass komanso kutsutsana kwa kuchuluka kwa CO2 komwe kulipo ndi mphamvu ya biomass.

Kodi zotentha za biomass ndi zotani?

Ziwotche za biomass zimagwiritsidwa ntchito ngati gwero la mphamvu ya biomass komanso m'badwo wa kutentha m'nyumba ndi nyumba. Amagwiritsa ntchito mafuta achilengedwe monga mapira amitengo, maenje a azitona, zotsalira zamnkhalango, zipolopolo zouma zipatso, ndi zina zambiri monga gwero la mphamvu. Amagwiritsidwanso ntchito kutenthetsa madzi m'nyumba ndi m'nyumba.

Ntchitoyi ndi yofanana ndi yotentha ina iliyonse. Ma boiler awa amatentha mafuta ndikupanga lawi yopingasa yomwe imalowa mdera lamadzi ndi chosinthira kutentha, potero ndikupeza madzi otentha a dongosolo. Kuti mugwiritse bwino ntchito kukatentha ndi zinthu zachilengedwe monga mafuta, makina oyikiramo akhoza kuikidwa omwe amasunga kutentha komwe kumapangidwa mofanananso ndi momwe mapanelo a dzuwa amagwirira ntchito.

Pofuna kusunga zinyalala zomwe zimagwiritsidwa ntchito ngati mafuta, ma boiler amafunikira chidebe chosungira. Kuchokera pachidebecho, pogwiritsa ntchito chopangira chosakira kapena chonyamulira, chimapita nacho kukatentha, komwe kuyaka kumachitika. Kuyaka kumeneku kumatulutsa phulusa lomwe liyenera kukhuthulidwa kangapo pachaka ndipo limadzikundikira mu phulusa.

Mitundu ya zotentha za biomass

Posankha ma boilers a biomass omwe tigule ndikugwiritsa ntchito, tiyenera kupenda makina osungira ndi kayendedwe ndi kayendedwe kawo. Ma boiler ena lolani kuwotcha mafuta amtundu umodzi, pomwe ena (monga ma bolet pellet) Amangolola mtundu umodzi wamafuta kuti uwotche.

Ziphika zomwe zimaloleza kuyatsa mafuta opitilira amodzi zimafunikira mphamvu yosungiramo zinthu popeza ndizazikulu komanso zamphamvu. Izi nthawi zambiri zimapangidwira mafakitale.

Kumbali inayi, timapeza ma boilers omwe amakhala ofala kwambiri pakati komanso omwe amagwiritsidwa ntchito kutenthetsa ndi madzi otentha a ukhondo kudzera muzipikika m'nyumba za 500 m2.

kukatentha nkhuni

Pali ma boilers ena omwe amagwiritsidwa ntchito ndi Kuchita bwino pafupi ndi 105% zomwe zikutanthauza kupulumutsa mafuta kwa 12%. Tiyeneranso kukumbukira kuti kapangidwe ka ma boilers kamadalira kwambiri chinyezi cha mafuta omwe tikufuna kugwiritsa ntchito.

  • Zowotcha zamafuta owuma. Ma boiler awa amakhala ndi inertia yotsika kwambiri ndipo nthawi zambiri amakhala okonzeka kukhalabe ndi lawi lamphamvu. Mkati mwa kukatentha kotentha kwambiri kumatha kufika poti amatha kupangitsa slag kukhala.
  • Zowotcha zamafuta onyowa. Chowotcha ichi, mosiyana ndi choyambacho, chimakhala ndi inertia yayikulu yotentha yotentha mafuta onyowa. Kapangidwe ka boiler kamayenera kulola kuti mafuta aziuma mokwanira kuti mpweya ndi mpweya wathunthu zitheke ndipo palibe utsi wakuda womwe umapangidwa.

Ma pletlet boilers-maenje azitona

Pali ma boilers angapo a biomass omwe amagwiritsa ntchito pellets ngati mafuta. Mwa onsewa timapeza:

Yodziyimira payokha pellet zotsalira zazomera kukatentha

Amagwiritsidwa ntchito kukhazikitsa ndi mphamvu pakati pa 91kW ndi 132kW ndipo amagwiritsa ntchito ma pellets ngati mafuta. Boiler yodziyimira payokha yakonzedwa kuti igwire ntchito. Zimaphatikizapo thanki yosungira, kompresa phulusa ndi njira yokoka yonyamula ma pellets. Zimapanganso ndalama zambiri chifukwa zimatha kuchepetsa kugwiritsidwa ntchito kwamafuta pochepetsa kutentha kwa mpweya woyaka. Pezani kubwerera kwa 95%. Lilinso ndi kuyeretsa basi makina. Ili ndi seti yama turbulators yomwe, kuphatikiza pakusunga utsi, kuti ikwaniritse magwiridwe antchito, ali ndi udindo woyeretsa zotsalira za phulusa m'malo opumira utsi.

Burner ili ndi makina oyeretsa phulusa. Gawo lakumunsi la thupi loyaka moto limakhala ndi njira yoyeretsera yomwe nthawi ndi nthawi imasamalira kutumiza phulusa lomwe limayaka nthawi yoyaka ku phulusa. Kuyeretsa kumachitika ngakhale poyatsa chowotchera, zomwe zimapangitsa kuti zisasinthe kuyika bwino ndikuchepetsa kuwotcha.

Zophikira nkhuni

Kumbali inayi, timapeza ma boomass omwe mafuta ake ndi nkhuni. Pakati pawo timapeza:

Kutentha kwapamwamba kwambiri

Awa ndi ma boiler obwezeretsa moto pamitengo yankhuni. Nthawi zambiri amakhala ndi osiyanasiyana mphamvu zitatu pakati pa 20, 30 ndi 40 kW.

Ubwino wamalo otentha ndi awa:

  • Mphamvu yamagetsi yomwe imachepetsa kugwiritsa ntchito mafuta. Mphamvu yomwe yapezeka ndi 92%, yomwe imaposa 80% yofunikira malinga ndi kukhazikitsa.
  • Kulipira kudziyimira pawokha mpaka maola asanu ndi awiri.
  • Imasintha mphamvu yomwe imapangidwa chifukwa chofunikanso chifukwa cha makina ake amagetsi.
  • Imaphatikizapo chitetezo chotsutsana ndi kutenthedwa.

Ubwino wokhala ndi chowotcha cha biomass

Ubwino woyamba wodziwika ndi ndithudi mtengo wa zotsalira zazomera. Nthawi zambiri, mtengo wake umakhala wolimba chifukwa umadalira misika yapadziko lonse lapansi. Timanenanso kuti ndi mphamvu yotsika mtengo chifukwa imapangidwa kuchokera kuzinthu zakomweko motero ilibe ndalama zoyendera. Pokhala yopindulitsa kwambiri komanso yopikisana, imapereka chitonthozo kwa wogwiritsa ntchito.

Ubwino wachiwiri wodziwika ndikuti ndi ukadaulo wotetezeka komanso wotsogola. Ndiye kuti, kukonza kwake ndikosavuta ndipo magwiridwe ake ndi okwera. Mphunoyi ndi mafuta achilengedwe omwe, chifukwa chamtengo wapatali kwambiri, amapangitsa, munjira yowonjezeredwa komanso yopindulitsa, imapatsa zokolola zokolola pafupifupi 90%.

moto, nkhuni

Pomaliza, mwayi womveka bwino ndikuti imagwiritsa ntchito mphamvu yoyera komanso yosatha ngati yomwe ingapitsidwenso. Pakugwiritsa ntchito kwake imatulutsa CO2 popeza imayatsa mafuta, koma CO2 iyi siyitenga mbali chifukwa pakukula kwake, zopangidwazo zatenga CO2 nthawi ya photosynthesis. Apa ndiye pakatikati pa mkangano pakugwiritsa ntchito ndi kuipitsa mphamvu zamagetsi zomwe tiwona mtsogolo. Kuphatikiza apo, tili ndi mwayi kuti potenga nkhalango zotsamba zimathandiza kuyeretsa mapiri ndikupewa moto.

Tiyenera kunena kuti zotsalira zazomera ndi zomwe zimapezetsa ntchito anthu akumidzi komanso kuti ndizolemekeza kusamalira zachilengedwe.

Zoyipa za zotayira zotsalira zazomera

Ziwotche za biomass zili nazo mtengo wotsika wa calorific ngati tiziyerekeza ndi mafuta. Ma pellets ali ndi theka la mphamvu zamtundu wa dizilo. Chifukwa chake, tifunikira mafuta owirikiza kuti tikhale ndi mphamvu zofanana ndi dizilo.

Chifukwa mafuta monga pellets amakhala ochepa, danga lalikulu likufunika kuti lisungidwe. Nthawi zambiri, ma boilers amafunika silo kuti asunge mafuta pafupi.

Kutsutsana kwamalingaliro a CO2 mu mphamvu zamagetsi

Monga tikudziwa, kuti tigwiritse ntchito mphamvu zamafuta, tiyenera kuwotcha mafuta. Nthawi yoyatsa mafuta, tikutulutsa CO2 m'mlengalenga. Nanga mphamvu zamagetsi zotsalira ndi zotsalira ndizotani?

Pakukula ndi kukula kwa zopangira zomwe timagwiritsa ntchito kuwotcha, mbewu, kudulira, zotsalira zaulimi, ndi zina zambiri. Iwo akhala kuyamwa CO2 kuchokera mumlengalenga kudzera ku photosynthesis. Izi zimapangitsa kuti mphamvu ya CO2 yamagetsi ikhale yopanda ndale. Ndiye kuti, kuchuluka kwa CO2 komwe timatulutsa mumlengalenga powotcha mafuta achilengedwe kale kudalowetsedwa kale ndi zomera pakukula kwawo, chifukwa chake titha kunena kuti mpweya wathunthu uli zero.

Komabe, zikuwoneka kuti sizomwe zili choncho. Mosiyana ndi mafuta, CO2 imatulutsa poyatsira mafuta a biomass, amachokera ku kaboni yemwe adachotsedwa kale mumlengalenga momwemo. Chifukwa chake, sizisintha kuchuluka kwa CO2 m'mlengalenga ndipo sizimawonjezera kutentha.

mapalete

Poyaka mafuta amtundu uliwonse, zinthu zingapo zoyaka zimatha kupangidwa, zomwe nitrojeni (N2), carbon dioxide (CO2), nthunzi yamadzi (H2O), oxygen (O2 osagwiritsidwa ntchito kuyaka), carbon monoxide (CO ), nayitrogeni oxides (NOx), sulfure dioxide (SO2), osapsa (mafuta osapsa), mwaye ndi tinthu tolimba. Komabe, pakuwotcha zotsalira zazomera, ndi CO2 yokha ndi madzi omwe amapezeka.

Nchiyani chimachitika ndiye ndikutsutsana kumeneku kwa CO2? Inde, CO2 imapangidwa chifukwa cha kuyaka kwa zotsalira zazomera, koma izi zimawerengedwa kuti sizokwanira chifukwa akuti kuyaka kwa biomass sikuthandizira kukulitsa kutentha kwa dziko. Izi ndichifukwa choti CO2 yomwe imatulutsidwa ndi gawo lamlengalenga (ndi CO2 yomwe mbewu ndi mitengo zimayamwa mosalekeza ndikumasula kuti zikule) ndipo si CO2 yomwe yagwidwa panthaka yazaka zikwizikwi ndipo yamasulidwa pang'ono ya nthawi ngati mafuta.

Kuphatikiza apo, ziyenera kukumbukiridwa kuti kugwiritsa ntchito biomass energy kumapulumutsa kwambiri poyendetsa mafuta omwe, nawonso, amatulutsa CO2 yochuluka mumlengalenga ndikusintha kayendedwe kabwino ka chilengedwe.

Monga mukuwonera, pambuyo pamagawo awiriwa pa biomass, omwe ndi mphamvu yamagetsi yowonjezeredwa, yomwe ngakhale sichidziwika bwino, imathandizira kukonza chisamaliro cha chilengedwe ndipo ndi njira yamagetsi mtsogolo.
