Umthelela wesitshalo sokuxuba i-asphalt awukwazi ukubukelwa phansi. Iphinde ibe nomthelela omkhulu ekusebenzeni kahle kokushisisa kwepayipi le-asphalt. Lokhu kungenxa yokuthi izinkomba zokusebenza ezibalulekile ze-asphalt, njenge-viscosity kanye nokuqukethwe kwesibabule, zihlobene eduze nesiteshi sokuxuba i-asphalt. Ngokuvamile, i-viscosity enkulu, umphumela omubi kakhulu we-atomization, othinta ngokuqondile ukusebenza kahle komsebenzi nokusetshenziswa kukaphethiloli. Njengoba izinga lokushisa likhuphuka, i-viscosity yamafutha asindayo iyancipha kancane kancane, ngakho uwoyela we-viscosity ephezulu kufanele ushiswe ukuze uhambe kahle kanye ne-atomization.

Ngakho-ke, ngaphezu kokuqonda izinkomba zayo ezivamile, kuyadingeka futhi ukwazi kahle ijika le-viscosity-temperature yayo lapho uyikhetha ukuze uqinisekise ukuthi ukushisa kungenza i-asphalt ifinyelele i-viscosity edingwa yi-burner ngaphambi kwe-atomization. Lapho kuhlolwa uhlelo lokujikeleza kwe-asphalt, kwatholakala ukuthi izinga lokushisa lepayipi le-asphalt alihlangabezani nezidingo, okwenza i-asphalt epayipini iqine.
Izizathu eziyinhloko yilezi:
1. I-tank yamafutha esezingeni eliphezulu yamafutha ashisayo iphansi kakhulu, okuholela ekujikelezeni kabi kwamafutha ashisayo;
2. Ishubhu yangaphakathi ye-double-layer tube i-eccentric
3. Ipayipi likawoyela oshisayo lide kakhulu;
4. Ipayipi likawoyela oshisayo alizange lithathe izinyathelo ezifanele zokuhlukanisa, njll. Lezi yizici eziyinhloko ezithinta umphumela wokushisa.
