Posankha kutsekereza bwalo losungiramo malasha, eni mapulojekiti nthawi zambiri amakakamira pakati pa zinthu ziwiri: "Kuwunika kwachilengedwe kukubwera, ndiye tifunika kuwunikira kaye," kapena "Ndalamazo ndizokwera kwambiri, ndiye tidikire."
Njira ziwirizi zimanyalanyaza chida chofunikira chofanana: kuyerekezera mtengo wokwanira. Ikani kutayika kwa malasha, mtengo wa calorific, chinyezi, ndalama zoyendetsera fumbi ndi kugwiritsa ntchito malo mu chiŵerengero chimodzi, kenaka sinthani kukhala mtengo wa tani imodzi ya malasha yomwe imagwiridwa chaka chilichonse. Yankho nthawi zambiri limakhala lomveka bwino kusiyana ndi chidziwitso chokha.
Kodi Chosungira Chamalasha Chotsegula Chimatayika Chiyani Chaka chilichonse?
Kutayika kwa Makala
Kuwonongeka kwa kuchuluka kwa malasha pamalo osungiramo zinthu nthawi zambiri kumachokera ku magawo atatu: tinthu tating'ono tomwe timatengedwa ndi mphepo, malasha ophwanyidwa okokoloka ndi mvula yamphamvu, komanso kuwonongeka komwe kumachitika chifukwa cha okosijeni pakatha nthawi yayitali.
Miyezo yamakampani osindikizidwa imasiyana kwambiri kutengera njira yoyezera. Milandu ina yobwereketsa malo opangira malasha imasonyeza kutayika kwa malasha pafupifupi 0.5%, koma chiwerengerochi chimangotengera kusiyana kwa muyeso panthawi yotsitsa, kutsitsa ndikugwira ntchito mkati. Panyengo yanyengo, makutidwe ndi okosijeni ndi kuwonongeka kwa calorie zimaganiziridwanso, chiwopsezo chonse chotayika chimakhala 2% -5%.
Powerengera koyambirira, malingaliro apakati apakati a 1% -3% akulimbikitsidwa, osinthidwa malinga ndi mtundu wa malasha ndi nyengo yaderalo. Makhalidwe apamwamba angakhale oyenera kwa malasha osungunuka kwambiri omwe amasungidwa m'madera owuma, amphepo.
Kutayika kwa Mtengo wa Kalori
Malasha akakhala ndi mpweya, pyrite imakhudzidwa ndi mpweya ndi chinyezi, kuonjezera kutentha kwa katundu ndikupangitsa kuti zinthu zosasunthika zituluke. Njira imeneyi ndi yosasinthika.
Malo osungiramo malasha amatha kuchepetsa kutayika kwa ma calories pafupifupi 300-500 kcal/kg. Kwa malasha oyaka omwe ali ndi mphamvu ya calorific ya 5,500 kcal / kg, izi ndizofanana ndi pafupifupi 5% -9% ya mtengo wake wa calorific.
Zotayika izi sizikuwoneka pa zolemba za weighbridge. Komabe, malasha akamagulidwa pamtengo wolingana ndi calorie, amamasulira mwachindunji ndalama zomwe zatayika.
Kusamalira Chinyezi ndi Zida
Madzi a mvula omwe amalowa mu mulu wa malasha otseguka amatha kuwonjezera chinyezi ndi 2-3 peresenti. Izi zitha kuyambitsa zovuta zambiri zogwirira ntchito: kutsika kwa ma crusher, kutsetsereka kwa lamba wa conveyor, mafunde a malasha oundana m'nyengo yozizira komanso kutsika kwa boiler. Kwa malasha otumizidwa kunja, chinyezi chochulukirapo chingathenso kuchotsera mtengo kapena zilango zamakontrakitala.
Kugwirizana ndi Chilengedwe: Zomwe Ogwiritsa Ntchito Osunga Malasha Ayenera Kuziganizira
Miyezo Inayi ya Kuwongolera Fumbi
Kuchokera pamtengo wotsika mpaka wokwera, njira zodziwika bwino zowongolera fumbi ndi monga:
