Izikhungo zokuphehla ugesi ngamalahle e-United States zikhiqiza cishe 75 amathani ayisigidi omlotha wamalahle minyaka yonke. Uma kuqhathaniswa ne- 267 amathani ayisigidi kadoti amaMelika awakhiqiza ngonyaka, it makes sense to find alternative uses for coal fly ash to keep landfills from being overwhelmed with this residual matter.
Ohlangothini oluhle, cishe amaphesenti angamashumi amahlanu nesishiyagalombili omlotha wamalahle owenziwe ngaphakathi 2018 yasetshenziswa kabusha. Enye indlela yokwenza lokho ukuyisebenzisa ekukhiqizeni ukhonkolo. The Romans used a mixture of volcanic ash mixed with lime to create a very effective kind of concrete. It was invented Long before portland cement.
Ukusebenzisa fly ash from coal-fired power plants creates a similar chemical reaction when used in the production of concrete, okwenza kube indawo efanelekayo esikhundleni sokufakwa kukasimende. The significance of keeping fly ash out of landfills is huge, kodwa kukhona okunye ekulinganisweni kwemvelo.
Lapho kuphulukiswa usimende wase-portland, it leaves behind some of the hydrated lime. That is added with water to create a binding agent. Lapho umlotha we-fly usetshenziswa esikhundleni sikasimende, ivumela nomcako ukwelapha. Contributing to added strength and durability of hardened concrete in comparison to cement alone.
okubaluleke kakhulu, yehlisa kakhulu inani lamandla adingekayo ukukhiqiza usimende wase-portland. Cishe ithani lesikhutha likhishwa ekukhiqizeni ithani likasimende likaportland. While it is already combusted and therefore does not release additional CO2 upon being used in concrete. Ngethani ngalinye likasimende limiselelwe ngomlotha wezimpukane enhlanganisweni kakhonkolo, it can avoid a ton of carbon dioxide emissions.
Recycling fly ash does help to keep landfills from being overburdened. Ngaphezu kwalokho, kunciphisa nenani lamandla adingekayo ukukhiqiza ukhonkolo kanye nenani lesikhutha elikhishelwa emoyeni ngesikhathi senqubo yokukhiqiza ukhonkolo.
Ukhiye wokuqina nokuqina kwemikhiqizo yokwakha eyenziwe ngomlotha wempukane ukunciphisa okuqukethwe yikhabhoni nokulawula ikhwalithi yayo. I ST Izinsiza kusebenza & technology triboelectrostatic ibhande isihlukanisi can remove residual carbon coal char and generate a high quality consistent processed product, ProAsh®, into ebalulekile yabakhiqizi bakakhonkolo. Sihlinzeka ngemishini yesimanjemanje yokucubungula amaminerali. Xhumana nathi namuhla ukuthola eminye imininingwane.
