He hua rakara te rere awa (P), he hua ā-wawe i te tukanga e whakaputa ai i te hiko. Rāwātea pōhāhē, pēnei i te rākau o raro me te pūhāhā, whakatū ki raro o te ruma rakau i muri i te mutunga o te pūhono. Ka ara te apu rere i roto i ngā tāpae tākōpū me ngā rākau āhua, ā, kua tangohia e ngā pūhono hiko me tētahi pātūpa tātari ā-tuhi.
rere pungarehu he tānga ā- (SCM) ā, ka taea te whakamahi hei whakahōu wāhi mō te karika o te pānui i roto i te pūwhaka, whakahekea te hiahia me te hua o te pūrehe. Me pēhea tēnei āwhina ki te whakaiti i te wārangi kārewa o ngā hua pīra? Mō ia rākau rere e whakamahia ana ki te wāhi o te pūtake tawhito, kua āraia te āhua o te āhua o te kārewa waina. Nā tēnei i te nui o te pūngao e hiahiatia ana me te āhuahua tāwaiwai e hangaia ana e te āwhina—mai i te tukanga o nga mea rawi me te wera ā-waewae e hiahiatia ana hei hanga i te rerekete. Mō te tohutoro, Kotahi te āwhina o TE CO2 e ōrite ana ki te toru marama o ngā whakautu mai i tētahi putanga wawaenga. The amount of fly ash used in concrete annually, saves around 13 tauwhāwha mātā o te kōwai tāpiri o te waina.
Ipu ana i te rere rere rere i ētahi atu mātau taiao rānei i ngā kōhuru, ētahi atu mātau taiao. E ōrite ana kia rite tētahi āe hau waro ki te wawaenga o ngā wairua i hanga e ia Amerika i roto i tētahi rārangi wā e 455 rā. 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, ā, me te āhuatanga o te tangata whakawhiti ā-ā-whenua hei tanu i a ia kia haumaru.
Mā te ipu i ngā hua o te rere rere i te tiaki i ngā taonga rawi hōu kia kore e hiahiatia hei whakawai, ā, he whakaiti hoki i ngā waina o te rīra. Ka tiaki hoki i ngā rauemi tūturu mai i te whakaiti, whakaitia rānei.
Ko te ipu i te apu rere mai i ngā āhua o te rākau rere tōraro, he mātau āhua rānei ētahi atu mātau taiao. He maha tekau o nga tau o te rere o nga wā o te āwhata, i te wā katoa i hanga ai ki te kore o ngā kārehe. It allows for groundwater to seep in and come in contact with the fly ash. Ka puta mai tēnei i te tānga o ngā huānga pēnei i te āhua, āhua, āhua, rārangi me ētahi atu ki roto i te ripanga wai. Mā te ipu i te apu rere me te whakauru ki roto i tētahi taonga kāore anō pēnei i te pērī pēnei i te pākaha e tango ai i te kaha mo te whakawehenga o te pāhono.
Not all fly ash is created equal though. Lower-quality fly ash can still be used to stabilize soils and reduce erosion. But the finer the particles used in concrete, the easier the concrete is to place and finish. Fine fly ash also contributes to a higher-strength product that is more resistant to the elements and wear.
This is where ST Technology & Equipment comes in. Our proprietary tribo-electrostatic belt separator is capable of handling a high throughput using very little energy. More nui, it is able to separate fly ash down to very small particle sizes, providing operation with varying degrees of final product. The finer the fly ash, the higher the demand and price.
