Biomass boilers uye gakava reiyo CO2 chiyero

Mune yapfuura posvo isu takataura nezvazvo biomass simba . Kubva pane zvazviri, mashandiro ayo uye kwainobva kubva kune zvakanaka nezvayakaipira. Ini ndataura zvishoma nezve biomass boilers, asi ini handina kupinda mune zvakadzama sezvo ini ndichida kuiburitsa pano zvakadzama.

Mune ino post isu ticha taura nezvazvo akasiyana mabiomass mabhaira uye gakava reiyo CO2 muyero uripo nebiomass simba.

Chii chinonzi biomass boilers?

Biomass boilers anoshandiswa sosi sosi ye biomass simba uye ye chizvarwa chekupisa mudzimba nezvivakwa. Vanoshandisa mafuta echisikigo akadai semapango emapango, makomba emaorivhi, masara emasango, makoko akaomeswa emichero, nezvimwewo sosi yesimba. Izvo zvinoshandiswa zvakare kudziyisa mvura mudzimba nezvivakwa.

Iko kuvhiya kwakafanana nechero imwe bhaira. Aya mabhaira ivo vanopisa huni uye vanogadzira murazvo yakatwasuka inopinda mudunhu remvura uye chinjana kupisa, nokudaro ichiwana mvura inopisa yeiyo system. Kugonesa kushandiswa kweboiler uye zviwanikwa zviwanikwa semafuta, an accumulator anokwanisa kuiswa ayo anochengetedza kupisa kwakaburitswa nenzira yakafanana nemabatirwo ezuva ezuva.

Kuti uchengetedze marara ehupenyu anozoshandiswa sehuni, mabhaira anoda mudziyo wekuchengetedza. Kubva pamudziyo iwoyo, pachishandiswa sikuruu isingaperi kana yekudhonza, inoenda nayo kubhaira, uko kunoitika kupisa. Uyu mwoto unoburitsa dota rinofanira kudururwa kakawanda pagore uye rinounganidzwa mutirayiti.

Mhando dzebiomass boilers

Kana tichisarudza rudzi rwemabhoomass bhaira atinozotenga nekushandisa, isu tinofanirwa kuongorora iyo yekuchengetedza system uye yekufambisa uye yekubata system. Mamwe mabhaira bvumira kupisa kanopfuura rumwe rudzi rwemafuta, nepo dzimwe (dzakadai semabhaira epellet) Ivo vanongobvumira imwe chete mhando yemafuta kupisa.

Mabhaira anotendera anopfuura peturu mafuta kuti apiswe anoda hukuru hwekuchengetedza sezvo iwo ari makuru uye aine simba. Izvi zvinowanzoitirwa kushandiswa kwemaindasitiri.

Kune rimwe divi, isu tinowana mabhureti emapellet ayo ari akajairika kune masimba epakati uye ayo anoshandiswa kupisa uye nehutsanana mvura inopisa kuburikidza neanounganidza mudzimba dzinosvika mazana mashanu emamirimita.

Kune mamwe mabiomass boilers anoshanda ne kushanda padhuze ne105% zvinoreva kuchengetedza mafuta kwe12%. Isu tinofanirwa zvakare kufunga kuti dhizaini yemabhaira inoenderana zvakanyanya nehunyoro hwemafuta isu atinoda kushandisa.

• Mabhaira emafuta akaoma. Aya mabhaira ane yakadzika thermal inertia uye anowanzo gadzirirwa kuchengetedza yakanyanya murazvo. Mukati memoto tembiricha inogona kusvika kusvika pakakwirira zvekuti ivo vanokwanisa kumisikidza iyo slag.
• Mabhaira emafuta anonyorova. Iyi boiler, kusiyana neiyo yapfuura, ine yakakura thermal inertia yekukwanisa kupisa iyo yakanyorova mafuta. Dhizaini yebhailer inofanira kubvumira kuti mafuta aome zvakaringana kuitira kuti gasification uye oxidation zvikwane uye hapana hutsi hutema hunogadzirwa.

Pellet boilers-maorivhi makomba

Kune akasiyana akasiyana e biomass boilers anoshandisa mapellets semafuta. Pakati pavo vese tinowana:

Modular pellet biomass bhaira

Iyo inoshandiswa kuiswa pamwe nemasimba pakati pe91kW ne132kW uye anoshandisa mapine pellets semafuta. Iyi modular bhaira yakagadzirirwa kugadzirwa kwecascade. Inosanganisira iyo yekuchengetera tangi, iyo compressor ashtray uye yekukweva system yekutakura kwepellets. Iyo zvakare inogadzira kuchengetedza kukuru sezvo ichigona kudzikisa kushandiswa kwemafuta nekudzikisa tembiricha yemagasi emoto. Tora kudzoka kunosvika 95%. Iyo ine zvakare yakazara otomatiki yekuchenesa system. Iyo ine seti yeturbulators ayo, pamusoro pekuchengetedza iko kufamba kwehutsi, kuitira kuti ivandudze mashandiro, vane basa rekuchenesa madota emarara munzvimbo dzehutsi.

Icho chinopisa chine otomatiki dota yekuchenesa system. Chikamu chezasi chemuviri wemoto unopisa chine nzira yekuchenesa iyo nguva nenguva inotarisira kutumira madota anogadzirwa panguva yekutsva kune iyo ashtray. Kuchenesa kunoitwa kunyangwe neanomhanya anopisa, izvo zvinoita kuti zvikwanise kusachinja nyaradzo yekumisikidza uye kudzikisa kudyiwa kwebhailer.

Boilers yehuni

Kune rimwe divi, tinowana mabiomass boilers ane huni huni. Pakati pavo tinowana:

Yakanyanya kushanda gasi bhaira

Aya ndiwo anodzoreredza murazvo gasification mabhaira ematanda ehuni. Vanowanzove nehurefu emasimba matatu ari pakati pe20, 30 uye 40 kW.

Zvakanakira rudzi urwu rweboiler ndeizvi:

• Kubudirira kwesimba kwakanyanya kunoderedza kushandiswa kwemafuta. Unyanzvi hwakawanikwa i92%, inodarika iyo 80% inodiwa nemirau yekuisa.
• Kubhadharira kuzvimiririra kwemaawa manomwe.
• Iyo inogadzirisa simba rakagadzirwa kune iyo yekuda yekutenda kune yayo emagetsi modulation system.
• Inobatanidza chengetedzo sisitimu inopisa kupisa.

Zvakanakira kuve nebiomass bhaira

Yekutanga inonyanya kuzivikanwa mukana ndeye zvirokwazvo mutengo webiomass. Kazhinji, mutengo wayo unogadzikana nekuti hautsamire pamisika yepasi rose sezvinoita mafuta emafuta. Isu tinotaura zvakare kuti iri yakachipa simba sezvo ichigadzirwa kubva kune zviwanikwa zvemuno saka haina mari yekufambisa. Kuve unobatsira uye unokwikwidza, unopa hunyanzvi hwehupfumi kune mushandisi.

Chechipiri chakanakira mukana ndewekuti iyo yakachengeteka uye yepamberi tekinoroji. Ndokunge, kugadzirisa kwayo kuri nyore uye kushanda kwayo kwakakwira. Iyo pellet mafuta echisikigo ayo, nekuda kwekukosha kwaro kwakakosha, inoita, nenzira inokwenenzverwa uye inobatsira, inopa iyo boiler nezvibereko padyo ne90%.

Chekupedzisira, iyo yakajeka mukana ndeyekuti inoshandisa rakachena uye risingaperi simba sezvo richigadziriswa. Munguva yekushandisa kwayo inoburitsa CO2 sezvo ichipisa mafuta, asi iyi CO2 haina kwayakarerekera nekuti panguva yekukura kwayo nekusimudzira, iyo mbishi yakanyura CO2 panguva yefotosinthesisi Ino nhasi ndiyo nzvimbo yekukakavadzana mukushandiswa uye kusvibiswa kwesimba re biomass iro ratinozoona gare gare. Uyezve, isu tine mukana wekuti nekutora sango biomass inobatsira kuchenesa makomo uye kudzivirira moto.

Izvo zvinofanirwa kutaurwa kuti biomass ndiyo inopa mabasa kumaruwa uye kuti inoremekedza kuchengetedza nharaunda.

Kukanganisa kwebiomass boilers

Biomass boilers vane yakaderera calorific kukosha kana tikachienzanisa nemafuta. Pellets ane hafu yeiyo calorific simba redhiziri. Naizvozvo, isu tinoda kaviri mafuta kuti tiwane simba rakafanana nedhiziri.

Nekuti mafuta akadai semapellets akaderera mukuwanda, nzvimbo hombe inodiwa yekuchengetedza. Kazhinji, mabhaira anoda silo kuchengetedza mafuta padyo.

Kupokana kweiyo CO2 chiyero mune biomass simba

Sezvatinoziva, kuti tishandise biomass simba, tinofanira kupisa mafuta. Munguva yekupisa kwemafuta, tiri kuburitsa CO2 mumhepo. Saka simba rebiomass rakasiyana papi nemafuta?

Munguva yekukura nekusimudzira kwezvinhu zvakasvibirira zvatinoshandisa kupisa, zvirimwa, kuchekerera, zvisaririra zvekurima, nezvimwe. Ivo vanga vari kunotora CO2 kubva mudenga kuburikidza nefotosinthesisi. Izvi zvinoita kuti CO2 chiyero chebiomass simba chionekwe sechisina kwachakarerekera. Mune mamwe mazwi, huwandu hweEC2 hwatinoburitsa mudenga nekupisa mafuta echisikigo akambotorwa nezvirimwa panguva yekukura kwavo, saka zvinogona kutaurwa kuti huwandu hwemweya mudenga ma zero.

Nekudaro, zvinoita sekunge izvi hazvisizvo chaizvo. Kusiyana nemafuta, iyo CO2 inoburitswa nekupisa biomass peturu, inouya kubva kukabhoni iyo yainge yabviswa kare mumhepo muchimiro chimwechete chehupenyu. Naizvozvo, ivo havashandure chiyero cheCO2 mudenga uye havawedzere iyo greenhouse maitiro.

Mukupisa kwemhando ipi neipi yemafuta, zvinhu zvakawanda zvinopisa zvinogadzirwa zvinogona kugadzirwa, pakati payo iyo nitrogen (N2), carbon dioxide (CO2), mhute yemvura (H2O), oxygen (O2 isingashandiswe mumoto), carbon monoxide (CO ), nitrogen oxides (NOx), sulfur dioxide (SO2), isina kupiswa (isina kubatidza mafuta), sosi uye yakasimba zvikamu. Nekudaro, mukutsva biomass, chete CO2 nemvura zvinowanikwa.

Chii chinoitika ipapo neiyi gakava CO2 bharanzi? Chokwadi, CO2 inogadzirwa semhedzisiro yekupisa kwebiomass, asi izvi zvinoonekwa seyero zero nekuti zvinonzi kupisa kwebiomass hakuiti kuti kuwedzere kweye greenhouse effect. Izvi zvinodaro nekuti iyo CO2 inoburitswa chikamu chemuchadenga uripo (ndiyo CO2 inodyarwa nemiti zvinoramba zvichipinza nekusunungura kukura kwazvo) uye haisi iyo CO2 yakatorwa muvhu repasi kwezviuru zvemakore uye yakaburitswa munzvimbo pfupi yenguva kunge mafuta echisaririra.

Uye zvakare, inofanirwa kutariswa kuti kushandiswa kwesimba rebiomass kunoponesa kwakawanda mukutakurwa kwemafuta ayo, zvakare, anoburitsa huwandu hwakawanda hweEC2 mumhepo uye unoshandura muyero wezvakatipoteredza.

Sezvauri kuona, mushure memawadhi maviri ari biomass, inova simba rinowedzerwazve, iro kunyangwe risingazivikanwe zvakanyanya, rinobatsira mukuvandudza kuchengetedza kwenzvimbo uye isarudzo yesimba remangwana.
