Kushandisa loose biomass kugadzira pellet mafuta patembiricha yekamuri inzira iri nyore uye yakatwasuka yekushandisa simba rebiomass. Ngatikurukurei nemichina yekuumba tekinoroji yemashanga echirimwa nemi.

Mushure meiyo biomass zvinhu zvine yakasununguka chimiro uye yakaderera density yaiswa pasi pesimba rekunze, iyo mbishi inozopinda mumatanho ekugadzirisazve, mechanical deformation, elastic deformation uye plastiki deformation. Iyo inelastic kana viscoelastic cellulose mamorekuru akabatanidzwa uye akamonyoroka, Iyo vhoriyamu yezvinhu inoderedzwa uye density inowedzera.

Iyo yekumanikidza reshiyo yemhete inofa yebiomass pellet muchina michina inotaridza saizi yekuumbwa kwekumanikidza. Iyo cellulose yemukati yezvinhu mbishi semashanga echibage netsanga idiki, uye iri nyore kutsvedza kana yaburitswa nekunze kwemasimba, saka iyo yekumanikidza reshiyo yemhete inodiwa pakuumbwa idiki. , kureva kuti, kuumba kumanikidzika kuduku. Iyo cellulose yemukati ye sawdust yakakwira, uye iyo yekumanikidza reshiyo yemhete kufa inodiwa pakuumbwa yakakura, ndiko kuti, kuumbwa kwekumanikidza kwakakura. Naizvozvo, zvakasiyana biomass mbishi zvinhu zvinoshandiswa kugadzira yakaumbwa pellet mafuta, uye akasiyana mhete kufa compression inofanira kushandiswa. Kune zvigadzirwa zvebiomass zvine yakafanana cellulose zvirimo mune zvakabikwa, mhete inofa ine yakafanana compression reshiyo inogona kushandiswa. Kune izvo zvakataurwa pamusoro pezvigadzirwa, sezvo iyo yekumanikidza reshiyo yemhete inofa, iyo particle density inowedzera, kushandiswa kwesimba kunowedzera, uye kubuda kunowedzera. Kana imwe compression ratio yasvika, kuwanda kwezvikamu zvakaumbwa zvinowedzera zvishoma, kushandiswa kwesimba kunowedzera zvinoenderana, asi kubuda kunoderera. Mhete inofa ine compression ratio ye4.5 inoshandiswa. Iine sawdust seyakagadzirwa uye mhete inofa ine compression reshiyo ye5.0, density yemafuta epellet inogona kusangana nemhando yezvinodiwa, uye kushandiswa kwesimba kwechishandiso system kwakadzikira.

Iyo yakafanana mbishi inoumbwa mumhete kufa neakasiyana compression ratios, kuwanda kwepellet mafuta kunowedzera zvishoma nezvishoma nekuwedzera kweiyo compression reshiyo, uye mukati mehumwe huwandu hwekumanikidza reshiyo, density inoramba yakagadzikana, kana iyo compression reshiyo ichiwedzera kune imwe nhanho, Iyo mbishi haizokwanisi kuumbwa nekuda kwekunyanya kudzvanywa. Hukuru hwezviyo zvemupunga hwakakura uye madota acho akakura, saka zvinonetsa kuti mupunga uumbe zvimedu. Panyaya imwecheteyo, kuti uwane yakakura particle density, inofanirwa kugadzirwa uchishandisa Larger ring mode compression ratio.
Kupesvedzera kweraw material size particle pamamiriro ekuumba

Iyo particle size yebiomass raw materials ine simba guru pamamiriro ekuumba. Nekuwedzera kwekukura kwechikamu chedzinde rechibage uye tsanga mbishi zvinhu, kuwanda kwezvimedu zvekuumba kunoderera zvishoma nezvishoma. Kana iyo particle size yeiyo mbishi yakanyanya kudiki, inozokanganisawo particle density. Naizvozvo, kana uchishandisa biomass senge mashanga echibage uye tsanga seyakagadzirwa kugadzirwa kwemafuta emafuta, zvinonyanya kukodzera kuchengetedza saizi yechidimbu pa1-5 nun.

Kupesvedzera hunyoro mune feedstock pane density yepellet mafuta

Kune huwandu hwakakodzera hwemvura yakasungwa uye yemahara yemvura mumuviri webhaibheri, iyo ine basa rekuzora, izvo zvinoderedza kupesana kwemukati pakati pezvimedu uye kunowedzera kuyerera, nekudaro kukurudzira kutsvedza uye kukodzera kwezvikamu pasi pekuita kwekumanikidza. Kana mvura inogadzirwa nebiomass raw materials Kana hunyoro hwakanyanya kuderera, zvimedu hazvikwanisi kuwedzerwa zvakakwana, uye zvikamu zvakapoteredza hazvina kubatanidzwa zvakasimba, saka hazvigoni kuumbwa. Kana hunyoro hunenge hwakanyanya kukwirira, kunyange zvazvo zvimedu zvinogona kukwidziridzwa zvakakwana mugwara perpendicular kusvika pakunyanya kushushikana kukuru, uye zvimedu zvinogona kusanganisa pamwe chete, asi Sezvo mvura yakawanda mumucheka wakasvibirira ichiwedzerwa uye ichigoverwa pakati pezvikamu zvezvikamu, zvikamu zvezvikamu hazvigoni kubatanidzwa zvakanyanya, saka hazvigone kuumbwa.

Naizvozvo, kana michina nemidziyo yebiomass pellet ichishandisa biomass semashanga echibage netsanga semidziyo yekugadzira mafuta epellet, mwando wezvakagadzirwa unofanirwa kugara pa12% -18%.

Pasi pemamiriro ekunze ekupisa, panguva yekumanikidza kuumba maitiro ebiomass mbishi zvinhu, zvimedu zvinoremara uye zvinosanganiswa muchimiro chekubatana meshing, uye zvikamu zvezvikamu zvinosanganiswa muchimiro chekubatana. Izvo zviri mukati me cellulose mune mbishi zvinhu zvinotarisa kuoma kwekuumbwa Iyo yakakwirira iyo cellulose yemukati, inova nyore kuumba. Iyo particle size uye hunyoro hwehuwandu hwezvinhu zvakasvibirira zvine simba rakakura pamamiriro ekuumba.
