Allọ ọrụ ọkụ ndị na-ere n'ọkụ na United States na-ewepụta 75 nde tọn coal ash kwa afọ. Jiri ya tụnyere 267 nde tọn ahịhịa nke ndị America na-emepụta kwa afọ, it makes sense to find alternative uses for coal fly ash to keep landfills from being overwhelmed with this residual matter.
Na gbakwunye n'akụkụ, ihe dị ka pasent iri ise na asatọ nke ash ash na-emepụta na 2018 gbanwere ya. Otu uzo esi eme nke ahu bu iji ya mee ihe. 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.
iji fly ash from coal-fired power plants creates a similar chemical reaction when used in the production of concrete, nke na - eme ka ọ bụrụ ihe kwesịrị ekwesị iji dochie edo edo. The significance of keeping fly ash out of landfills is huge, mana enwere otutu ihe banyere gburugburu ebe obibi.
Mgbe Portland ciment na-agwọ, it leaves behind some of the hydrated lime. That is added with water to create a binding agent. Mgbe ada uyi na-eji n'ọnọdụ ciment, ọ na-ekwe ka wayo gwọọ ya. Contributing to added strength and durability of hardened concrete in comparison to cement alone.
ọzọ ihe, ọ na-ebelata oke ike dị mkpa iji mepụta ciment portland. Ihe fọrọ nke nta ka ọ bụrụ ton carbon dioxide na-ebupụta na mmepụta nke ton nke ciment Portland. While it is already combusted and therefore does not release additional CO2 upon being used in concrete. N'ihi na onye ọ bụla ton nke ciment dochie anya ada uyi na ihe ngwakọta, it can avoid a ton of carbon dioxide emissions.
Recycling fly ash does help to keep landfills from being overburdened. Ọzọkwa, ọ na-ebelatakwa ike achọrọ iji mepụta ihe ọkụkụ yana carbon dioxide a na-ewepụta na mbara igwe n'oge usoro mmepụta ihe.
Isi ihe na-eme ka ike na ngwa ngwa nke ngwaahịa ụlọ nke ejiri ash na-efe bụ iji belata ọdịnaya carbon ya ma chịkwaa ogo ya. The ST Equipment & Technology nke triboelectrostatic belt separator can remove residual carbon coal char and generate a high quality consistent processed product, ProAsh®, ihe bara uru maka ndị na-emepụta ihe. Anyị raara onwe anyị nye inyere ndị ahịa anyị aka na ụwa anyị bi na ya. Kpọtụrụ anyị taa maka ozi ndị ọzọ.
