Ubufakazi bokuqhuma kwe-Shenhai
Isilinganiso se-bt4 ezintweni ezingaqhumisi sibonisa amapharamitha amabili ayinhloko. Ukwengeza, othi 'b’ ku-bt4 isho Ikilasi IIb, okubonisa ukusetshenziswa kwayo ezindaweni okungezona ezezimayini.

B
Igama elithi ‘B’ ikhombisa izinga legesi endaweni, kunqunywa ngamaleveli ereferensi okuhlola. Lokhu kuhlukaniswa kubala ngokuyinhloko izikhala ezinkulu lapho amagesi angadlula khona kanye namandla awo amancane okuthungela.. Ihlukaniswe ngamaleveli amathathu: Ikilasi A, B, kanye no-C. Izindawo zekilasi A ziphephile uma kuqhathaniswa, Ikilasi B liyingozi kakhulu, futhi Ikilasi C liyingozi, nakuba kungavamile kakhulu. Imishini yokuvikela ukuqhuma yekilasi C iyasebenza kuzo zombili izindawo zekilasi A no-B, Izinto zokusebenza zekilasi B zifanele izilungiselelo zekilasi A, kanye nezinto zokusebenza ze-Class A ezezindawo ze-Class A kuphela. Ngenxa yalokho, Isigaba B ngokuvamile siyizinga elijwayelekile lezinto ezingaqhumi emakethe. Uhlu lwalezi zigaba luyi-Class C > Ikilasi B > Ikilasi A.
T4
I-T4 ichaza i- izinga lokushisa ukuhlukaniswa ngaphakathi kwemvelo, esekelwe amagesi’ amaphuzu okushisa ahlobene. Ukuhlukaniswa kwezinga lokushisa okuphezulu kudinga amazinga okushisa aphansi okusebenza kanye nokucaciswa kwemishini eqinile. Lezi zigaba zenzelwe izindinganiso ezithile zokukhiqiza, edinga ukukhethwa kwezinto ezingaqhumi ukuze zifane namazinga okushisa emvelo angempela. Imishini enesilinganiso se-T4 yakhelwe ukusebenza emazingeni okushisa asukela ku- 135 kuya ku-200 ° C.
Isilinganiso sokuvikela ukuqhuma kwe-bt4 yisona esivame kakhulu, ukuhlinzeka ukusebenziseka okubanzi kanye nokukhethwa okubanzi kwezindawo ezisebenzayo.
