Ukusebenzisa i-biomass ukuvelisa amafutha e-pellet kwiqondo lobushushu legumbi yindlela elula nethe ngqo yokusebenzisa amandla e-biomass. Masixoxe nawe ngobuchwephesha bokwenza ingca yezityalo kunye nawe.

Emva kokuba izinto ze-biomass ezinokwakheka okuxekekileyo kunye noxinano oluphantsi luphantsi kwamandla angaphandle, izinto ezikrwada ziya kudlula kwizigaba zohlengahlengiso, ukuguqulwa komatshini, ukuguqulwa kwe-elastic kunye nokuguqulwa kweplastiki. Iimolekyuli ze-inelastic okanye i-viscoelastic cellulose zidibene kwaye zixutywe, Umthamo wezinto eziphathekayo uyancitshiswa kwaye ubuninzi buyanda.

Umlinganiselo wokunyanzeliswa komsesane wokufa kwezixhobo zoomatshini be-biomass pellet umisela ubungakanani boxinzelelo lokubumba. Umxholo cellulose izinto ekrwada ezifana izikhondo umbona kunye neengcongolo zincinane, kwaye kulula deform xa extruded ngamandla angaphandle, ngoko ke ucinezelo ratio of umsesane die ezifunekayo ukubumba encinane. , oko kukuthi, uxinzelelo lokubumba luncinci. Umxholo we-cellulose we-sawdust uphezulu, kwaye i-compression ratio ye-ring ring efunekayo ekubunjweni inkulu, oko kukuthi, uxinzelelo lokubumba lukhulu. Ke ngoko, izinto ezahlukeneyo ze-biomass ekrwada zisetyenziselwa ukuvelisa i-pellet fuel ebunjiweyo, kwaye ucinezelo olwahlukileyo lomsesane kufuneka lusetyenziswe. Kwizinto ze-biomass ezinomxholo ofanayo we-cellulose kwizinto eziluhlaza, i-ring die kunye ne-compression ratio efanayo ingasetyenziswa. Kwizinto eziluhlaza ezikhankanywe ngasentla, njengoko umlinganiselo wokunyanzeliswa kwe-ring ring ukhula, ukuxinana kwamasuntswana kwanda, ukusetyenziswa kwamandla kwanda, kwaye imveliso iyanda. Xa umlinganiselo othile wokunyanzeliswa ufikeleleke, ubuninzi beengqungquthela ezibunjiweyo zanda kancane, ukusetyenziswa kwamandla kwanda ngokufanelekileyo, kodwa umphumo uyancipha. Umsesane wokufa kunye nomlinganiselo woxinzelelo we-4.5 usetyenziswa. Nge-sawdust njengento ekrwada kunye nendandatho yokufa kunye nomlinganiselo wokunyanzeliswa kwe-5.0, ubuninzi be-pellet fuel inokuhlangabezana neemfuno zomgangatho, kwaye ukusetyenziswa kwamandla kwenkqubo yezixhobo kuphantsi.

Izinto ezifanayo ezikrwada zenziwe kwi-ring die kunye nemilinganiselo yoxinzelelo eyahlukeneyo, ukuxinana kwamafutha e-pellet kwandisa ngokuthe ngcembe ngokunyuka komlinganiselo woxinzelelo, kwaye ngaphakathi koluhlu oluthile lomlinganiselo wokuxinzelela, ubuninzi buhlala buzinzile, xa umlinganiselo wokunyanzeliswa unyuka ukuya kumlinganiselo othile, Impahla ekrwada ayiyi kuba nako ukusekwa ngenxa yoxinzelelo olugqithisileyo. Ubungakanani bengqolowa ye-rice husk bukhulu kwaye umxholo womlotha mkhulu, ngoko kunzima ukuba i-rice husk yenze amaqhekeza. Kwizinto ezifanayo, ukuze ufumane ingxinano enkulu yamasuntswana, kufuneka iqulunqwe kusetyenziswa umlinganiselo omkhulu wokunyanzeliswa kwe-ring mode.
Impembelelo yobungakanani bamasuntswana ekrwada kwiimeko zokubumba

Ubungakanani besuntswana lezinto eziluhlaza ze-biomass zinempembelelo enkulu kwiimeko zokubumba. Ngokunyuka kobukhulu beqhekeza le-corn stalk kunye ne-reed raw materials, ukuxinana kwamasuntswana okubumba kuncipha ngokuthe ngcembe. Ukuba ubungakanani be-particle ye-raw material incinci kakhulu, iya kuchaphazela ukuxinana kwamasuntswana. Ngoko ke, xa usebenzisa i-biomass njengeziqu zengqolowa kunye neengcongolo njengezinto eziluhlaza zokuvelisa i-particle fuel production, kulungele ngakumbi ukugcina ubungakanani be-particle kwi-1-5 nun.

Impembelelo yokufuma kwi-feedstock kubuninzi be-pellet fuel

Kukho umlinganiselo ofanelekileyo wamanzi abophekileyo kunye namanzi akhululekile kumzimba webhayoloji, onomsebenzi we-lubricant, onciphisa ukungqubuzana kwangaphakathi phakathi kweengqungquthela kunye nokwandisa umbane, ngaloo ndlela ukhuthaza ukutyibilika kunye nokulungelelaniswa kwamaqhekeza phantsi kwesenzo soxinzelelo. Xa umthamo wamanzi wezinto eziluhlaza ze-biomass Xa umthamo womswakama uphantsi kakhulu, iinqununu azikwazi ukwandiswa ngokupheleleyo, kwaye iinqununu ezijikelezayo azidibanisi ngokuqinileyo, ngoko azikwazi ukubunjwa. Xa umxholo womswakama uphezulu kakhulu, nangona iinqununu ziyakwazi ukwandiswa ngokupheleleyo kwi-perpendicular ukuya kuxinzelelo oluphezulu lwenqununu, kwaye iinqununu ziyakwazi ukuthungelana, kodwa Ekubeni amanzi amaninzi kwizinto eziluhlaza akhutshwe kwaye asasazwe phakathi kweengqungquthela zeengqungquthela, iinqununu zeengqungquthela azikwazi ukudibanisa ngokusondeleyo, ngoko ayikwazi ukubunjwa.

Ngoko ke, xa oomatshini be-biomass pellet kunye nezixhobo zisebenzisa i-biomass efana nezikhondo zombona kunye neengcongolo njengemathiriyeli ekrwada yokuvelisa amafutha e-pellet, umthamo wokufuma wemathiriyeli ekrwada kufuneka ugcinwe kwi-12% -18%.

Ngaphantsi kweemeko eziqhelekileyo zokushisa, ngexesha lokunyanzeliswa kwenkqubo ye-biomass ekrwada, iinqununu ziphazamisekile kwaye zidibene ngendlela yokubambisana, kunye neengqungquthela zengqungquthela zidibene ngendlela yokubambisana. Umxholo we-cellulose kwizinto eziluhlaza umisela ubunzima bokubumba Ukuphakama kwe-cellulose umxholo, kulula ukubumba. Ubungakanani be-particle kunye nomswakama wezinto eziluhlaza zinempembelelo enkulu kwiimeko zokubumba.
