I-boiler sisixhobo esisebenzisa amandla obushushu sepetroli okanye eminye imithombo yamandla ukufudumeza amanzi ashushu okanye i-steam. Intsingiselo yokuqala yembiza ibhekisa kwisitya samanzi esishushu emlilweni, kwaye isiko libhekisa kuloo ndawo itshiswe kuyo ipetroli. Umbhali ubandakanya iinxalenye ezimbini: imbiza kunye nezixhobo. Amanzi ashushu okanye i-Steam eveliswe kwi-boiler inokubonelela ngokungqalileyo amandla okufudumeza kwimveliso yemizi-mveliso kunye nobomi babantu, kwaye unokuguqulwa ibe ngamandla omatshini ngokusebenza kwe-Steam kwimveliso yombane kwimveliso yombane kwimveliso yombane kwimveliso. I-Boiler ebonelela ngamanzi ashushu ibizwa ngokuba yiBoiler eshushu yeBoiler, ikakhulu isetyenziselwa ubomi, ikwanesicelo esincinci kwimveliso yemizi-mveliso. I-Steam Ukuvelisa i-Boiler ibizwa ngokuba yi-Steam Boiler, edla ngokubizwa ngokuba yi-boiler, isetyenziswa kakhulu kwizikhululo zamandla omzimba, iinqanawa, amashishini e-loomotive kunye nemizi mveliso kunye namashishini amnyama kunye namashishini amashishini.
