Eziteshini zamandla e-thermal, ukushiswa kwesikhumba kukhipha inani elikhulu le-ash njengomkhiqizo. Izinhlelo zokuphatha i-ash ezisebenzayo zibalulekile ekuqhutshweni kahle kwalezi ziteshi, ziqinisekisa ukuhlangabezana nemithetho yokuvikelwa kwemvelo nokusebenza kahle. Le ndatshana inikeza umbono ophelele wokuthi izinhlelo zokuphatha i-ash zisebenza kanjani eziteshini zamandla e-thermal.
Ezikhathini zamandla aphezulu, kukhiqizwa izinhlobo ezimbili eziyisisekelo zothuli:
Uhlelo lokuphathwa kwe-ash ngokuvamile luqukethe lezi zinto ezilandelayo:
– I-flay ash iqoqwa kumoya ophuma emgibeleni usebenzisa ama-electrostatic precipitators noma ama-bag filters.
– I-asher eliqoqiwe bese ilethwa ezindaweni zokugcina ngezinjini zomoya.
– I-ashe eliphansi iqoqwa emanzini agcwele ezitokisini zaphansi kwefurnace.
– I-athayi isuswa ngemuva kokusebenzisa ama-scraper agxilile noma ama-pump athumelayo.
– Umoya ophumayo uhanjiswa ngentambo usebenzisa umoya ophumelelayo.
– Le ndlela iyasebenza kahle transporti yezikhafa.
– U-ash ophansi uhlanganiswa namanzi ukuze kudaleke i-slurry.
– I-slurry iphushwa ngaphakathi kweziteshi zokuphakela ukuze ibekwe ezindaweni zokulahla.
– I-ashe igcinwa okwesikhashana ezindaweni ezikwi-silo ezihlinzekwe ngamasistimu okunciphisa uthuli.
– Lokhu kuvimba umlotha ukuba ube semoyeni futhi ubange ukungcoliswa kwemvelo.
– U-ash ubekwe ezindaweni zokuphosa noma emathangeni e-ash.
– Ngaphandle kwalokho, uthuli lungaphinde lusetshenziswe ezokwakha, njengezinto ezifana ne-cement namabhulokhi.
Amaphuzu aphephile kagesi kumele ahambisane nemithetho eqinile yokuvikelwa kwemvelo ephathelene nokulahleka kwendudu. Izinto ezisemqoka okufanele zicatshangelwe zifaka:
Izinhlelo zokuphatha uthuli zibalulekile ekusebenzeni kweziteshi zamandla ezishisayo, ziqinisekisa ukuthi imikhiqizo ethuliwe iphethwe kahle nangendlela sustainable. Ngokwazi izingxenye nezinyathelo ezibandakanyekayo, iziteshi zamandla zingathuthukisa ukusebenza kwazo nokunciphisa umthelela wazo endaweni.
