The Environmental Uru Iji ofufe Ash Na Concrete

Ofufe ash bụ ngwaahịa combustion coal (CCP), ihe sitere na ikpochapu kol na usoro nke na-eme oku eletrik. Ntụ na-adịghị mma, dị ka ala ash na ji esi mmiri ọkụ slag, dozie na ala nke ụlọ combustion mgbe ikpochapu ya zuru ezu. Ofufe ash adahade ke osisi iyuzucha stacks na flue gas ma wepụrụ electrostatic precipitators na a akwa nyo baghouse.

ofufe ash bụ ihe mgbakwunye nke ciment (SCM) ma enwere ike iji ya dochie anya simenti portland na imepụta ihe, na-ebelata mkpa maka na ịmepụta ciment. Kedu ka nke a si enyere aka belata akara ukwu carbon nke ngwaahịa? N'ihi na onye ọ bụla ton nke ada uyi na-eji ebe nke omenala ciment, A na-ezere ihe dị ka otu tọn carbon dioxide anwuru. Nke a bụ n'ihi ume a chọrọ na carbon dioxide nke a na-emepụta site na ịmịpụta simenti — ma site na usoro ịda mba nke akụrụngwa na okpomoku ọkụ sitere na mmanụ ọkụ nke chọrọ iji mepụta ciment. Maka nkọwa, otu ton nke CO2 bụ ihe dịka ọnwa atọ nke ọkụ si na ụgbọ ala. The amount of fly ash used in concrete annually, saves around 13 nde carbon nke ikuku carbon dioxide na emeputa.

Recycling ada uyi site na mkpofu ahihia ma obu ndi ozo nwere uru ndi ozo gburugburu ebe obibi. Otu tọn ash ash bụ otu ihe nha anya na mkpofu ahịhịa nke onye America ọ bụla mepụtara n’ime oge ụbọchị 455. Recycling the fly ash reduces space required for landfills. It reduces the amount of carbon dioxide produced by the trucks that need to transport the ash from the power plant to the landfill, tinyekwara igwe eji ebu ụwa iji lie ya n’enweghị nsogbu.
Recycling ada uyi na-eme na-azọpụta ọhụrụ akụrụngwa si mkpa ka a ga-egwuputa ma na-ebelata carbon dioxide anwuru. Ọ na-azọpụtakwa ihe ndị sitere n'okike ka a ghara ibelata ma ọ bụ belata.

Recycling ada uyi site na akụkọ ihe mere eme ada uyi impoundments ma ọ bụ landfills nwere ndị ọzọ gburugburu ebe obibi uru dị ka nke ọma. Ọtụtụ iri afọ ijiji ash landfills na impoundments mgbe mgbe wuru na-enweghị liners. It allows for groundwater to seep in and come in contact with the fly ash. Nke a nwere ike ime ka ị nweta ihe ndị dị ka arsenic, boron, sọlfọ, lithium na ndị ọzọ n'ime mmiri mmiri. Imegharị efegharị ntụ ma tinye ya n'ime ihe na-enweghị ịcha ụcha dị ka ihe na-ewepụ ikike nke mmetọ mmiri mmiri..

Ọ bụghị ihe niile ada uyi na-kere hà. Lower-quality fly ash can still be used to stabilize soils and reduce erosion. But the finer the particles used in concrete, ihe nfe ka idoro ma mechaa. Ezi ada uyi na-etinyekwa aka na ngwaahịa dị ike dị elu nke na-eguzogide ọgwụ na ihu igwe.

Nke a bụ ebe ST Technology & Akụrụngwa na-abata. Nke anyị tribo-electrostatic belt separator nwere ike ijikwa nnukwu ikike iji obere ume. ọzọ ihe, ọ bụ ike ikewapụ ada uyi ala obere obere urughuru nha, providing operation with varying degrees of final product. Ihe finer the ada uyi, nke ka elu na ọnụahịa na ọnụahịa.
