Izinhlobo eziningi ezahlukene zama-boilers atholakalayo emakethe zenza kube nzima kubathengi ukuthola efanelekile. Lesi sihloko sizogxila kumathiphu aphezulu okudingeka uwacabangele ngaphambi kokuthola umshini wokubilisa, isabelo semakethe sama-boilers, isidingo sabo, kanye nezinga lokukhula elilindelekile. Izophinde ikhulume ngezinhlobo ezahlukene zemishini yokubhayela etholakalayo, kanye nobuhle nobubi bayo. Ngakho funda ukuze uqinisekise ukuthi ungakhetha ibhoyili yakho elandelayo ngokuzethemba.

Isidingo kanye nesabelo semakethe semishini yokubhayela
Ngo-2020, usayizi wemakethe wemishini yokubilisa umlilo embonini waba yigugu US $ 2.7 billion. Izibikezelo zesikhathi esizayo zikhomba ukuthi le makethe izokhula ngenani lokukhula elihlanganisiwe lonyaka (CAGR) elingaphezu kuka-4.5% kuze kube ngu-2028. Eqinisweni, imakethe yase-US yamabhoyili omlilo kulindeleke ukuthi ifinyelele ngaphansi kwama-US $ 2.6 billion ngo-2028.
Ngokombiko wango-2022 we-Future Market insights, inani lemakethe yomhlaba wonke lemishini yokubhayela yokuhlala lingama-US $29.5 billion. Ngakho-ke ngenani lokukhula lika-5.4% CAGR kule minyaka eyishumi ezayo, lo sayizi wemakethe kulindeleke ukuthi ukhule ufinyelele ku-US $ 49.9 billion.
Amathiphu amahlanu aphezulu okuthenga umshini wokubilisa ongcono kakhulu
1. Amandla omshini wokubilisa
Okukhipha Amandla we ama-boilers ingavezwa ngamaphawundi esitimu esilethwa ngehora noma amandla e-Boiler horse (MBTU). Ngokuvamile, isitimu esikhiqizwa ibhoyela ngokuvamile siyahlukahluka kuye ngomfutho kanye nezinga lokushisa. Iyunithi evamile yokuveza lokhu i-BTU.
Kuye ngenani, ake sithi, ithagethi yokusetshenziswa kwamanzi ashisayo, usayizi a umshini we-boiler ngoba igumbi liyisici esibucayi. Imishini yesistimu kanye ne-preheat boilers ngokuvamile ishisa amanzi ukuze agcinwe emathangeni afakwe ngokwanele. Ezimeni ezinjalo, izinga lokugeleza alivamile ukuba bucayi kangako.
Sekukonke, amakamelo ajwayelekile ane umthwalo wokushisa osukela ku-34,000BTU - 68,000BTU. Lokho kusho ukuthi nama-boilers ajwayelekile angaba mancane kakhulu kunama-combi boilers. Qaphela ukuthi ama-boilers anamandla amahhashi ahlukene akalwa nge-BPH. Ngakho-ke, i-boiler enamandla amahhashi angu-30 BPH inamandla okukhipha amandla angaba ngu-1, 004, 000 BTU, kanti i-6BPH imele cishe ama-200, 800 BTU. Lapho amandla e-hose ephakama, ukusebenza kangcono.
Ngokuvamile, isimo sezulu esibandayo sidinga i-50 BTU/sq.ft kanye negumbi likabhayela elingu-35 BTU/sq.ft ukuze libe nesimo sezulu esimaphakathi. Nokho, amazinga okushisa ashisayo adinga amagumbi okubhayela ane-20 BTU/sq.ft.
2. Ukusebenza kahle komshini wokubilisa
Uma umshini wokubhayela usebenza kahle, inani likaphethiloli lincane okungenzeka liwusebenzise. Ngokuyisisekelo, lokhu kubhekisela ekusebenzeni kahle kukaphethiloli ukuya emanzini noma ku-fuel-to-steam. Ama-boilers anamuhla anokusebenza kahle okungafika ku-94%, okusho ukuthi ama-boilers anjalo alahlekelwa kuphela u-6% wamandla angena ekusebenzeni kwawo.
Ukusebenza kahle kokusetshenziswa kukaphethiloli kwaminyaka yonke (AFUE) kuyisici esibalulekile lapho uthenga ibhayela. Lokhu kubhekisela esilinganisweni sokusebenza kahle kokushisa kwesikhala sebhayela. Lapho i-AFUE iphakeme, umshini we-Boiler usebenza kahle kakhulu. Isibonelo, ibhayela engu-90% ye-AFUE izokhipha 90 BTUS ngo-100BTUS wokufakwa kwegesi.
Ngokuvamile, ama-boilers awela ezigabeni ezimbili eziyinhloko, kanti esiyinhloko singesomusi namanzi. Ukuze kwandiswe ukusebenza kahle kukabhayela, ukwehliswa kwawo noma isilinganiso sokulawula kufanele kuvumele ukushintshashintsha okubanzi komthwalo wokushisisa wesakhiwo. Ibhayela kufanele ihambisane nezidingo zokushisa zesakhiwo ukuze kusebenze kahle kakhulu.
3. Izidingo zokungenisa umoya kubhayela
Ama-boilers adinga indawo eyanele ene-oxygen eyanele ukuqinisekisa ukugeleza komoya okwanele. Imishini yesimanje yama-boiler ivalwe ngamakamelo, namakamelo omlilo avalwe ngokuphelele. Ikamelo elinjalo ngokuvamile lingena umoya ngepayipi elishisayo.
Izikhala eziqinile, njengamakhabethe, kufanele futhi zibe nezinyathelo zokulawula izinga lokushisa, lapho ukushaywa umoya kuyisici esibalulekile. Ezimweni ezinjalo, ikhabethe linomnyango ovulekile onesikhala esingu-300mm phezulu. Lesi sikhala simelela isikhala esiphakathi kwekhabethe nengaphezulu lebhayela. Ngaphezu kwalokho, kufanele kube nesikhala esingu-100 mm ngaphansi kwekhabethe. Udonga olulodwa nangaphambili kwekhabethe kufanele kube negebe elingu-700mm.
4. Indawo etholakalayo
Isikhala esibekelwe ukufaka ubhayela sincike ohlotsheni lomshini wokubiyela ngokwawo. Futhi njengoba ama-boilers eza ngosayizi abahlukahlukene, kuhle ukuthi ubuyekeze indawo etholakalayo okukhulunywa ngayo. Ngokuphawulekayo, ama-boilers odongeni alungele izindawo ezincane, kanti amakamelo amakhulu angakwazi ukuhlalisa kahle ama-boilers aphansi.
Ama-boilers odonga ahlangene, athule, futhi angasindi. Lokhu kwenza ukufakwa kwabo kufanelekile ekhishini nezindawo zokugezela. Lapho ufaka i-boiler odongeni, qinisekisa kuqala ukuthi kukhona ukukhanya kwemvelo ekamelweni. Futhi, ukungena komoya wokunikezela kufanele kuqinisekise kahle ukuthi umoya uyashintsha ngaphakathi kwegumbi izikhathi ezi-3 ngehora.
Ama-boilers anjenge-combi, isistimu, nama-boilers avamile angafakwa kalula phansi ekamelweni elikhulu. Iphansi kufanele lenziwe ngezinto ezingashi. Okungcono nakakhulu uma phansi kungenziwa ujenga ngezitini zikakhonkolo. Futhi ukuphakama kufanele okungenani kube ngu-100mm. Ukwengeza, imbobo ye-gas chimney kanye ne-boiler kumele kuhambisane nokusebenza kahle nokusebenza okuphezulu.
5. Umthombo wamandla
Ukuze i-boiler evamile isebenze kahle, idinga umthombo wamandla ozinzile. Okubaluleke nakakhulu, ukusetshenziswa kwayo kwamandla kufanele kufane nomthwalo wokushisa wesakhiwo. Ngaphandle kwalokho, ungafaka i-economizer kubhayela yakho kungakhathaliseki ukuthi ishubhu lomlilo noma umshini weshubhu lamanzi. Ngokuyisisekelo, i i-economizer yehlisa izinga lokushisa lifike ku-270 Fahrenheit. Ukunciphisa izinga lokushisa kudlule uphawu lokungu-270F kungase kubangele igesi ye-flue ukuthi iminyene kakhulu. Ithiphu yokulawula izinga lokushisa le-flue gas ukulawula izinga lokugeleza kwamanzi okuphakelayo.
Izinhlobo ezahlukene boilers
Amashubhu omlilo kanye nama-boilers amanzi yimiklamo emibili eyinhloko yama-boiler. Ngokuhlakanipha kokusebenza kwale mishini yomibili iyahluka: isibonelo, amashubhu omlilo asetshenziselwa amanzi ashisayo nesitimu, kuyilapho ama-boilers amanzi asetshenziselwa ngokuyinhloko ukukhiqiza isitimu. Okuningi ngale mishini yokubhayela kubalulwe ngezansi.
1. Fire tube boilers
Ama-boilers we-fire tube, owaziwa nangokuthi ama-boilers wegobolondo, asebenza ngokudlulisa amagesi avuthayo ashiswa isishisi sawo esikhiqizwe yi-cylindrical compartment ecindezelweyo equkethe amashubhu amancane. Amanzi ashiswa ngamandla okushisa asuka endaweni enomfutho aze aphenduke abe isitimu.
Ngokuvamile, ama-fire tube boilers ayindlela enhle kakhulu kulabo abangakwazi ukukhokhela ama-boilers amanzi. Enye yezindawo zayo ezinkulu zokuthengisa ukuthi inomklamo olula, ohlangene, omncane, futhi kulula ukuyisebenzisa njengoba ingadingi amakhono ayinkimbinkimbi.
buhle
- Idinga amakhono ambalwa ukuze isebenze kahle
- Ukuze uthole okukhiphayo okufanayo, ama-boilers amashubhu omlilo abiza kancane kunamashubhu amanziUmklamo olula nokugcinwa okungabizi kakhulu
- Ukwelashwa kwamanzi okuphakelayo akudingekile
bawo
- Ukushintshashintsha komthwalo akulula ukukusingatha
2. Ama-boilers amashubhu wamanzi
Ngokwezici, ama-boilers amanzi ziyahlukahluka kakhulu. Isibonelo, ama-boilers wamanzi wegobolondo ajikeleza amanzi ngaphakathi kwamashubhu, nomthombo wokushisa ozungeze amashubhu. Eziteshini zikagesi, amashubhu amanzi avamile anezincazelo ezilandelayo:
- Kufika kumabha angu-160 esitimu esinomfutho ophezulu
- Kushise kakhulu umusi ongafika ku-550°C
- Ukukhishwa kwe-Steam kwe kuze kufike ku-500 kg / s
Njengama-boilers amagobolondo ephakheji, ama-boilers amashubhu amancane amanzi angenziwa futhi ahlanganiswe ngokuphelele abe iyunithi eyodwa yokusebenza, kuyilapho amayunithi amakhulu ahlanganiswa endaweni enezingxenye ezihlukahlukene ezakha iyunithi yonke. Imvamisa, iningi lemishini yokubiyela amanzi ngamashubhu isebenza ngesimiso se-thermosiphon, esivame ukubizwa ngokuthi ukujikeleza kwamanzi emvelo.

Isiphetho
Ukukhetha i-boiler efanele kuncike kakhulu ekusetshenzisweni, uhlobo, nokusebenza. Labo abafuna ukwenza ngcono i-hydronic heat system emakamelweni abo kufanele bacabangele ama-bosch condensing boilers. Ngenxa yokusebenza kahle komshini komshini, ungenisa izindleko eziphansi kakhulu zenyanga. Ngokuphawulekayo, isistimu ye-combi boiler iyisibonelo esijwayelekile sesistimu eyonga amandla ezoqinisekisa ukutholakala okuhlala njalo kwamanzi ashisayo nokushisa endlini. Ukuze uthole okwengeziwe, ungavakashela Chovm.com ukuze upheqa amanye ama-boilers angcono kakhulu adayiswayo.
