IZIHLELO ZOKUVUMA NGAMUNYE

Ibhayela ye-CFR isekela ukushiswa kwegumbi/ukuphuma okuqondile kanye nezilungiselelo zokushiswa/ukuphuma okuqondile. Isistimu yokukhipha umoya kufanele ilinganiswe ngokuhambisana nokushicilelwa kwakamuva kwe-National Fuel Gas Code (ANSI Z223.1/ NFPA54) njengesisetshenziswa esisizwa abalandeli beSigaba I. Kumayunithi afakwa umoya ngamunye, isistimu yokukhipha umoya kufanele yakhelwe ukuze ukucindezela kukalwe kube phakathi kwebanga elingu--0.01 ukuya ku- -0.08″ wc Xhumana nommeleli wakho wendawo wezentengiso we-AERCO ukuze uthole imihlahlandlela yokulinganisa komoya ovuthayo. Kufanele kuqashelwe ukuthi ukugeleza kanye ne-vent noma ububanzi be-duct kunemiphumela ebaluleke kakhulu ekwehleni kwengcindezi yesistimu iyonke. Uma kuzosetshenziswa ipayipi elingunxande, bheka ithebula eliseSigabeni 13.3 ukuze uthole usayizi wepayipi eliyindilinga elinokwehla okufanayo kokucindezela ngobude bepayipi elingunxande.

IZINHLELO EZIKHONAYO

KUBALULEKILE:

Xhumana nommeleli wakho wezokuthengisa we-AERCO noma i-AERCO International ukuze uthole usizo lokuklama futhi uphindeview lapho uklama i-exhaust ehlukahlukene kanye nezinhlelo zomoya ezivuthayo eziningi.

Ezimweni eziningi kungase kusebenze ukuxhuma amayunithi amaningi usebenzisa umoya odonsayo ophihliwe noma ukumiswa kokukhipha umoya. Kodwa-ke, lapho amayunithi amaningi exhunywe yisikhala somoya esiphindiwe noma isikhipha umoya, ukusebenza kweyunithi enikeziwe kungase kuthikamezeke ngamanye, uma isistimu yokungenisa umoya noma yokushiswa ingaklanywanga kahle. Amasistimu ajwayelekile aklanywe kahle ajwayelekile angafakwa azovimbela "ukusebenzelana kokusebenza" phakathi kwamayunithi. Ama-boilers asizwa abalandeli be-AERCO CFR aklanyelwe afaneleka ukusetshenziswa ezinhlelweni ezivamile zokungenisa umoya. Isistimu yokungenisa umoya evamile izolinganiswa ngokuhambisana nokushicilelwa kwakamuva kwe-National Fuel Gas Code (ANSI Z223.1/ NFPA54) njengento esetshenziswa abalandeli yeSigaba I. Kumayunithi avamile afaka umoya, isistimu yokukhipha umoya kufanele yakhelwe ngendlela yokuthi ingcindezi elinganiswa kuyo yonke indawo ibe yinegethivu, phakathi kwebanga elingu--0.01 ukuya -0.08″ wcThintana nommeleli wakho wendawo wezentengiso we-AERCO ukuze uthole imihlahlandlela yokulinganisa umoya ovuthayo.

Izindlela Ezinhle Kakhulu

Ukuxhuma emsebenzini ovamile wokubhodla amapayipi noma amapayipi kufanele kufezwe ngendololwane engu-45° lapho kugeleza khona lapho kubhodla umoya. "Ama-Tees" akumele asetshenziselwe ukufeza lokhu kuxhumana - bheka uMdwebo 11-1. Ubuncane obuncane obudingekayo bokungena kwembobo eqondile eqondile kufanele kube ngamafidi angu-10 (3.1 m) kuze kufike ekunqamulweni okume mpo ngemva kokuba ibhayili yokugcina ixhunywe kunhlokweni evamile.

Ukuxhumana kwamaqembu amayunithi akumele neze kwenziwe “nge-tee”. Njengoba kukhonjisiwe kuMfanekiso 11-2, shintsha isiqondiso ngomunye wamapayipi amakhulu bese uxhuma ububanzi obuthathu besibili (ububanzi besigaba esivamile) ukusuka kuleli jika ngoxhumano lwama-45°.

Umfanekiso 11-3 ubonisa “isigaba sokushintsha kwesikhala” lapho wenza ukuxhumana okungu-45° kube okuyinhloko. I-main ingahlala futhi ku-diameter eyodwa, inqobo nje uma ilinganiswa nenani eliphelele lamayunithi aphumayo futhi ukuxhumana kwegatsha okungu-45° kugcinwa. Ukusetshenziswa komhlangano "woshintsho" onconyiwe kuzonciphisa ukwehla kwengcindezi yesistimu iyonke.

Isistimu yokukhipha umoya kufanele njalo imiswe phezulu ngo-¼-intshi ngonyawo (21 mm per m) wokugijima ukuya lapho kunqanyulwa khona umoya (bona Umfanekiso 11-4). Kunconywa kakhulu ukusebenzisa usayizi wepayipi elilodwa lapho ugijima okuvamile (Bheka Umfanekiso 11). -4). Ama-boiler vents e-CFR akumele axhunywe kulawa amanye amamodeli e-AERCO noma izisetshenziswa zabanye abakhiqizi.

Ukususwa Kwe-Boiler Ekhona Ekungeneni Okujwayelekile

Lapho ibhayela ekhona ikhishwa ohlelweni oluvamile lokungenisa umoya, isistimu yokungenisa umoya evamile ingase ibe nkulu kakhulu ukuze kungene umoya ofanele wezinto zikagesi ezisele zixhunywe kuyo. Ngesikhathi sokukhishwa kukabhayela okhona, izinyathelo ezilandelayo zizolandelwa ngesisetshenziswa ngasinye esisele sixhunywe ohlelweni oluvamile lokungenisa umoya olusetshenziswayo, kuyilapho ezinye izinto ezisasele zixhunywe ohlelweni oluvamile lokungenisa umoya zingasebenzi.
