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.

Isixhobo esifanayo esikrwada senziwe kwi-ring die kunye ne-compression ratios ezahlukeneyo, ubuninzi bepellet fuel banda ngokuthe ngcembe ngokunyuka komlinganiselo woxinzelelo, kwaye phakathi koluhlu oluthile lomlinganiselo woxinzelelo, ubuninzi buhlala buzinzile, xa umlinganiselo wokunyanzeliswa unyuka ukuya kwi-compression ratio. umlinganiselo othile, Izinto ekrwada aziyi kuba nako ukubunjwa ngenxa yoxinzelelo olugqithisileyo. Ubungakanani bengqolowa ye-rice husk inkulu 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 kwamaqhekeza kunye nokwandisa umbane, ngaloo ndlela kukhuthazwa ukutyibilika kunye nokulungelelaniswa kwamasuntswana 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 wokufuma uphezulu kakhulu, nangona amasuntswana anokwandiswa ngokupheleleyo kwicala le-perpendicular ukuya kuxinzelelo oluphambili oluphezulu, kwaye amaqhekeza anokuthi adibanise omnye nomnye, kodwa Ekubeni amanzi amaninzi kwizinto eziluhlaza akhutshwa kwaye asasazwa phakathi kweengqimba zamasuntswana. , i-particle layers ayikwazi ukudibaniswa 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.
