I-Reciprocating Grate Ye-Biomas Boiler

I-grate ephindaphindayo yamabhayela e-biomass iyingxenye ebalulekile eklanyelwe ukushisa izinto zokubasa ze-biomass, njengama-wood chips, utshani, amakhoba elayisi, nezinto ezifanayo. Ifakwe ngokuyinhloko ngaphansi kwegumbi lomlilo kuma-boilers we-biomass. Isidingo sawo esiyinhloko sisekutheni izibaseli ze-biomass zivame ukuba nezimo ezingajwayelekile, umswakama okungenzeka ube mkhulu, kanye nezici zomlotha ezihlukene, okwenza kube nzima ngama-grate angashintshi ajwayelekile ukuthi afinyelele ukuvutha okuzinzile nokusebenza kahle. Lolu hlobo lwe-grate lunezingqimba ze-grate ezishintshayo ezinyakazayo nezigxilile, ezishayelwa umshini ukuze zenze ukunyakaza okuhambisanayo. Lesi senzo kancane kancane futhi ngokulinganayo siphushela uphethiloli phambili ngenkathi sinyakazisa umbhede kaphethiloli futhi sigqugquzela ukususwa komlotha ne-slag. Lo mshini ubalulekile ekuqinisekiseni ukushiswa kukaphethiloli okuphelele, ukuvimbela ukugqwala ku-grate, kanye nokuvumela ukusebenza okuzenzakalelayo okuqhubekayo.

Ngenxa yokuguquguquka kwayo okukhethekile kukaphethiloli kanye nokuthembeka kokusebenza, ama-grate aphindaphindayo asetshenziswa kabanzi emkhakheni wokushiswa kwe-biomass, ikakhulukazi kumaphrojekthi wokushisisa ezimbonini namaphrojekthi okukhiqiza amandla e-biomass. Umsebenzi wabo oyinhloko uwukwenza umbhede ovuthayo oguquguqukayo nolawulekayo, ukusabalalisa izinqubo zokomisa uphethiloli, i-pyrolysis, ukuvutha, nokutubeka ngendlela ehlelekile kuzo zonke izindawo ezihlukene ze-grate. Ngokulungisa isivinini kanye nemvamisa yokuhamba kwe-grate, isikhathi sokuhlala kanye nokuqina komlilo kaphethiloli esithandweni somlilo kungalawulwa ngokunembile. Lokhu kukhulisa ukukhishwa kwamandla kuphethiloli kuyilapho kunciphisa ngokuphumelelayo okuqukethwe kwekhabhoni yomlotha wezimpukane futhi kunciphisa ukukhishwa kwegesi eyingozi. Isebenza njengesiqinisekiso esiyisisekelo sokufeza ukusebenza kahle, okuhlanzekile, nokuzinzile kwama-biomass boilers.

Insimbi-ekwazi ukumelana nokushisa

 

Esigabeni sensimbi{0}}ekwazi ukumelana nokushisa, amabanga avamile ahlanganisa i-RTCr16 ne-RTCr20, phakathi kokunye. Izinzuzo zalezi zinto ezisetshenziswayo ilele ezindlekweni zazo eziphansi kanye nokuba nezindawo ezithile zokumelana nokushisa nokugqwala, okuzenza zifanelekele amaphrojekthi anezimo zokusebenza ezithambile noma lawo azwelayo ekutshalweni kwezimali kokuqala. Umkhawulo wabo omkhulu ukuwohloka kwesakhiwo sezinto ezincane ngaphansi kwamazinga okushisa aphakeme isikhathi eside, okuholela ekwehleni kokusebenza kwemishini. Ikakhulukazi, ukumelana kwabo nokugqwala kwe-chlorine okuvela kumafutha e-biomass kubuthakathaka, okuvame ukuphumela empilweni yesevisi elinganiselwe.

High-i-chromium cast iron

 

Okwamanje, into esetshenziswa kabanzi iwukugqokwa okuphezulu-kwe-chromium-okuqinile okuqinile okungazweli, namabanga ajwayelekile afana ne-BTMCr20 ne-BTMCr26. Lezi zinto zifaka ubulukhuni obuphezulu nokumelana nokugqoka okuhle kakhulu. Ngokuthembela kokuqukethwe kwawo okuphezulu kwe-chromium, angenza ungqimba oluvikelayo lwe-chromium oxide eminyene phezulu, amelane ngokuphumelelayo nezinto ezonakalisayo emlotheni. Ukuzijwayeza kubonise ukuthi isikhathi sabo sokuphila lapho sishisa izinhlobo ezihlukahlukene ze-biomass singcono kakhulu kunesokushisa okuvamile{6}}ku-iron ekwazi ukumelana nokushisa. Kodwa-ke, ukungalungi kwabo kufaka phakathi ukuqina okuphezulu kanye nokungazweli ukushaqeka okushisayo, okubenza bathambekele ekuqhekekeni ngaphansi kokuguquguquka okukhulu kwezinga lokushisa.

Ukushisa kwe-Austenitic{0}}insimbi engazweli

 

Kuzinhlelo zokusebenza ezidinga kakhulu, kusetshenziswa i-austenitic heat resistant steel steel{0}}, njenge-SCH24 (25Cr-20Ni). Lolu hlobo lwento, ngenxa yokuqukethwe kwe-chromium ephezulu kanye ne-nickel, lubonisa amandla amahle kakhulu, ukuqina, kanye nokumelana nokunyuka emazingeni okushisa aphezulu. Ingakwazi futhi ukumelana nokukhathala okushisayo kanye nokugqwala okukhulu kwe-chlorine. Ngakho-ke, ikhethelwa izingxenye ezibalulekile zezitshalo zamandla amakhulu noma amabhayela aphatha izibaseli ezidla kakhulu. Yiqiniso, izindleko zayo ze-alloy eziphakeme kakhulu futhi zikhawulela uhla lwayo lokusebenza.
