Lokhu okubizwa ngokuthi i-coal-water slurry kubhekisela ekudakaleni okwenziwe ngamalahle angama-70% agayiwe, amanzi angu-29% kanye nezithasiselo zamakhemikhali ezingu-1%. Kuwuphethiloli owuketshezi ongapontshwa futhi ufakwe inkungu njengowoyela owuphethiloli. Ingathuthwa futhi igcinwe ezindaweni ezikude, futhi inani layo le-calorific lilingana nengxenye yamafutha kaphethiloli. Isetshenziswe kuma-boilers ajwayelekile abaswa uwoyela, kwiziko le-cyclone, ngisho nasezithandweni zokulayisha ngokushesha zohlobo lweketango. Uma kuqhathaniswa ne-gasification yamalahle noma i-liquefaction, indlela yokucubungula udaka lwamalahle emanzini ilula, ukutshalwa kwezimali kuncane kakhulu, futhi izindleko nazo ziphansi, ngakho njengoba yathuthukiswa maphakathi nawo-1970, idonse ukunaka kwamazwe amaningi. izwe lami liyizwe elikhulu elikhiqiza amalahle. Itshale imali eningi kule ndawo futhi yazuza ulwazi olucebile. Manje sekungenzeka ngisho nokwenza udaka lwamanzi amalahle agxile kakhulu kumpushana wamalahle okhiqizwa ukugeza amalahle.

Izithasiselo zamakhemikhali zodaka lwamanzi amalahle empeleni zifaka izinto ezihlakazekayo, iziqinisi, ama-defoam nama-corrosives, kodwa ngokuvamile zibhekisela ezigabeni ezimbili zama-disperants kanye nezinzinzisi. Indima yesengezo yilezi: ngakolunye uhlangothi, amalahle ahlutshiwe angahlakazwa ngendlela efanayo endaweni yamanzi ngendlela yezinhlayiyana eyodwa, futhi ngasikhathi sinye, kuyadingeka ukwenza ifilimu ye-hydration ebusweni bomhlaba. i-particle, ukuze i-slurry yamanzi yamalahle ibe ne-viscosity ethile kanye ne-fluidity;
