Kana mafuta akazara (gasi) anopisa ane mashandiro epamusoro achine akafanana epamusoro pekuita moto kana akaiswa pane bhailer zvinoenderana zvakanyanya nekuti gasi rine simba maitiro ezviviri izvi.Kufananidza kwakanaka chete kunogona kupa kutamba kwakazara kuita kweanopisa, kuwana yakagadzika kupisa muchoto, kuwana inotarisirwa kubuda kwesimba rekupisa, uye kuwana yakanakisa yekupisa kushanda kwebhailer.
1. Kufananidzwa kwemaitiro emagetsi egasi
Chinhu chimwe chete chinopisa chinopisa chakafanana nemurazvo wemoto, uyo unopfapfaidza gidhi remoto muchoto (chamber combustion), unowana kupisa kunoshanda muchoto uye kuburitsa kupisa.Iko kushanda kwekupisa kwechigadzirwa kunoyerwa nemugadziri wekupisa.inoitwa mukamuri chaiyo yekupisa.Naizvozvo, iwo mamiriro ezviyedzo zvakajairwa anowanzo shandiswa semamiriro ekusarudza ezvinopisa uye boilers.Aya mamiriro anogona kupfupikiswa sezvizvi:
(1) Simba;
(2) Kuyerera kwemhepo muchoto;
(3) Saizi yenzvimbo uye geometric chimiro (dhayamita uye kureba) yechoto.
Iko kunonzi kuenzanirana kwegasi dynamic maitiro kunoreva dhigirii iro izvi zvitatu zvinosangana nazvo.
2.Simba
Simba rehuni (kg) kana vhoriyamu (m3/h, pasi pemamiriro akajairwa) ehuturu hunogona kupisa paawa kana yanyatsotsva.Inopawo iyo inoenderana yekupisa simba kubuda (kw/h kana kcal/h).)Iyo boiler inoyerwa kugadzirwa kweutsi uye kushandiswa kwemafuta.Izvo zviviri zvinofanirwa kufanana pakusarudza.
3. Gasi rinodzvinyirira muchoto
Mune oiri (gasi) bhailer, iyo inopisa gasi inoyerera inotanga kubva kune inopisa, inopfuura nemuchoto, inopisa kupisa, flue gasi muunganidzi uye epoust pombi uye inoburitswa kumhepo, ichigadzira mvura inopisa.Musoro wekumanikidza wepamusoro wemhepo inopisa inoyerera inogadzirwa mushure mekupisa kunoyerera mumugero wechoto, semvura iri murwizi, ine musiyano wemusoro (kudonha, musoro wemvura) uchiyerera uchidzika.Nekuti madziro echoto, machani, magokora, mabaffles, gorges uye chimneys zvese zvine kupikisa (kunonzi kuyerera kupikisa) pakuyerera kwegasi, izvo zvinokonzeresa kurasikirwa kwekumanikidza.Kana musoro wekumanikidza haugone kukunda kurasikirwa kwekumanikidza munzira, kuyerera hakuzowanikwe.Naizvozvo, imwe flue gasi kudzvanywa kunofanirwa kuchengetedzwa muchoto, iyo inonzi back pressure yehuni.Kune ma boilers asina dhizaini dhizaini, iyo yevira yekumanikidza inofanirwa kunge yakakwira kupfuura yekumanikidza kwemuchadenga mushure mekufunga nezvekumanikidzwa kwemusoro kurasikirwa munzira.
Kukura kwekumanikidzwa kwemashure kunobata zvakananga kubuda kwechipisa.Kumanikidzwa kwemashure kune hukama nehukuru hwechoto, kureba uye geometry yeflue.Maboiler ane hombe kuyerera anopikisa anoda high burner pressure.Kune chaiyo inopisa, musoro wayo wekumanikidzika une kukosha kukuru, unoenderana nehombe damper uye mamiriro makuru ekuyerera kwemhepo.Kana iyo intake throttle ichichinja, huwandu hwemhepo uye kudzvanywa kunoshandukawo, uye kubuda kwehuni kunochinjawo.Musoro wekumanikidza idiki kana mhepo yemhepo idiki, uye musoro wekumanikidza wakakwira kana huwandu hwemhepo hwakakura.Kune imwe pombi, kana mhepo inosvika yakawanda yakakura, kuyerera kwemhepo kunowedzera, izvo zvinowedzera kudzvinyirira shure kwechoto.Kuwedzera kwekudzvinyirirwa kwemashure kwechoto kunodzivisa kubuda kwemhepo yehuni.Naizvozvo, iwe unofanirwa kuzvinzwisisa pakusarudza burner.Simba rayo curve inofananidzwa zvine musoro.
4. Kufurira kwehukuru uye geometry yevira
Kune mabhoilers, saizi yenzvimbo yevira inotanga kusarudzwa nekusarudzwa kwekupisa kwekupisa kwechoto panguva yekugadzira, zvichibva pane iyo vhoriyamu yevira inogona kutsanangurwa pakutanga.
Mushure mekunge vhoriyamu yevira yakatemwa, chimiro chayo uye saizi inofanirawo kutariswa.Nheyo yekugadzira ndeyekushandisa zvizere vhoriyamu yevira kudzivirira makona akafa zvakanyanya sezvinobvira.Inofanirwa kunge iine humwe hudzamu, nzira inoyerera yekuyerera, uye yakakwana yekudzosera nguva yekugonesa mafuta kupisa zvinobudirira muchoto.Nemamwe mashoko Nemamwe manzwi, regai marimi akadzimwa kubva muchoto ave nenguva yekumbomira yakakwana muchoto, nekuti kunyangwe zvimedu zveoiri zvidiki kwazvo (<0.1mm), musanganiswa wegasi wakabatidzwa uye watanga kupisa usati waburitswa. kubva pamoto, asi hazvina kukwana.Kana choto chakanyanya kudzika uye nguva yekumbomira isina kukwana, kupisa kusingashande kuchaitika.Mumamiriro ezvinhu akaipisisa, kupera kweCO level kunenge kwakaderera, mumamiriro ezvinhu akaipisisa, utsi hutema huchabudiswa, uye simba haringasviki zvinodiwa.Nokudaro, pakusarudza kudzika kwechoto, urefu hwemurazvo hunofanira kufananidzwa zvakanyanya sezvinobvira.Kune iyo yepakati backfire mhando, dhayamita yekubuda inofanira kuwedzerwa uye vhoriyamu inobatwa negasi rekudzoka inofanira kuwedzerwa.
Iyo geometry yechoto inokanganisa zvakanyanya kuyerera kwekupokana kwemhepo inoyerera uye kufanana kwemwaranzi.Iyo bhailer inoda kupfuura nekudzokororwa kwekugadzirisa isati yakwanisa kuita mutambo wakanaka neanopisa.
