Amathangi okushisa ibitumen awuhlobo lwemishini yokwakha umgwaqo futhi kancane kancane asetshenziswa kabanzi. Njengoba ziyimishini emikhulu, kuyadingeka ukunaka ukuphepha okusebenzayo okufanele lapho uzisebenzisa. Yimiphi imisebenzi okufanele yenziwe ngemva kokuba ithangi lokushisisa itiyela selikhona? Namuhla ngizokuchazela kabanzi:

Ngemva kokufakwa kwethangi lokushisisa itiyela endaweni, sicela uhlole ukuthi izixhumo zizinzile futhi ziqinile, ukuthi izingxenye ezisebenzayo ziyaguquguquka yini, ukuthi amapayipi acacile yini, nokuthi izintambo zikagesi zilungile yini. Lapho ulayisha itiyela okokuqala ngqa, sicela uvule ivalve yokukhipha umoya ukuze uvumele itiyela ukuba Lifinyelele Bushelelezi kusifudumezi. Ngaphambi kokushisa, sicela ugcwalise ithangi lamanzi ngamanzi, vula i-valve ukuze izinga lamanzi ku-generator ye-steam lifinyelele ukuphakama okuthile, bese uvala i-valve.
Lapho ithangi lokushisisa itiyela lisetshenziswa ezimbonini, izingozi ezingaba khona kanye nokulahlekelwa okubangelwa ukusebenza okungafanele kufanele kugwenywe ezicini ezine: ukulungiselela ngaphambi kokuqala, ukuqalisa, ukukhiqiza kanye nokuvalwa. Ngaphambi kokusebenzisa ithangi lokushisisa itiyela, hlola izinga loketshezi lwethangi likadizili, ithangi likawoyela esindayo, nethangi lebitumen. Lapho ithangi liqukethe i-1/4 yamafutha, kufanele igcwaliswe ngesikhathi, futhi ukuphepha kwabasebenzi kanye nemishini yokusiza endaweni ngayinye kufanele kuqinisekiswe.
