Okokuqala, inokubonelela ngesixa esikhulu samandla okusetyenziswa kwiinkalo ezahlukeneyo ezifana nokuveliswa kwamandla, ukuthutha, kunye nemveliso yemizi-mveliso. Ngaphezu koko, i-fuel, igesi, kunye ne-steam nazo zineempawu zexabiso eliphezulu le-calorific kunye noxinano lwamandla aphezulu, kwaye zinokukhupha isixa esikhulu samandla ngexesha elifutshane. Ukusebenza kwayo kwe-thermal yi-92% okanye ngaphezulu, ukuphuculwa kokusebenza kwe-thermal kunokunciphisa ixesha lokusebenza kunye nokugcina ixesha kunye neendleko. Ukongezelela, inkqubo yokutsha yamafutha, igesi, nomphunga icocekile ngokwentelekiso, ikhupha igesi encinane yokuphuma, yaye ayinayo impembelelo encinane kwimekobume.
Nangona kunjalo, umphunga wegesi yepetroli unemida ethile. Okokuqala, ixabiso lepetroli lomphunga werhasi yamafutha liphezulu kunelo lejenereyitha yomphunga wombane. Kwezinye iindawo ezineemeko zoqoqosho ezimbi, ukusetyenziswa komphunga werhasi yamafutha kunokunyusa iindleko zamandla. Okwesibini, nangona inkqubo yokutsha yerhasi yerhasi yerhasi yomphunga icocekile noko, iya kuvelisa irhasi yokukhupha nezinto ezingcolisayo, eziya kuba nefuthe elithile kumgangatho womoya. Ukongezelela, kukho iingozi ezithile zokhuseleko kwindawo yokugcina nokuthutha i-fuel, igesi kunye ne-steam. Amanyathelo ahambelanayo kufuneka athathwe ukuqinisekisa ukhuseleko. Kananjalo ayisebenzi kwamanye amashishini ngaphandle kwamadangatye avulekileyo.
Ukushwankathela, umphunga wegesi yamafutha, njengejenereyitha yomphunga eqhelekileyo, uneengenelo ezininzi kodwa unemida ethile. Ngoko ke, xa sikhetha amafutha, igesi nomphunga, kufuneka sihlolisise iingenelo nemida yawo size sikhethe ngokweemfuno zethu.
