Mugihe cyo gufata umwanzuro wo gufunga ikibanza cyo kubikamo amakara, ba nyir'umushinga bakunze gutsimbarara hagati yintambwe ebyiri: “Igenzura ry’ibidukikije riraza, bityo rero tugomba kubanza kubitwikira,” cyangwa ngo “Ishoramari ni ryinshi, bityo tugomba gutegereza.”
Inzira zombi zirengagiza igikoresho kimwe cyingenzi: kugereranya ibiciro byuzuye. Shira igihombo cyamakara, agaciro karori, ubushuhe, igiciro cyo kugenzura ivumbi no gukoresha ubutaka mubare umwe, hanyuma ubihindure ikiguzi kuri toni yamakara ikoreshwa buri mwaka. Igisubizo mubisanzwe kirasobanutse kuruta gushishoza wenyine.
Ni iki Ububiko bw'amakara afunguye butakaza buri mwaka?
Gutakaza Ubwinshi bw'amakara
Gutakaza ingano yamakara kububiko bwafunguye mubisanzwe biva ahantu hatatu: ibice byiza bitwarwa numuyaga, amakara yashegeshwe yogejwe nimvura nyinshi, no kwangirika guterwa na okiside mugihe cyo kubika igihe kirekire.
Ibipimo byinganda byatangajwe biratandukanye cyane kuburyo bwo gupima. Bimwe mu bitegura uruganda rukora amakara yerekana retrofit ivuga ko yatakaje amakara agera kuri 0.5%, ariko iyi mibare ireba gusa itandukaniro ryo gupimwa mugihe cyo gupakira, gupakurura no gutunganya imbere. Iyo ikirere, okiside hamwe na kalorifike yangirika nabyo birasuzumwa, igipimo rusange cyigihombo gisanzwe kigereranijwe kuri 2% –5%.
Kubara ibanzirizasuzuma, hasabwa igitekerezo cyo hagati ya 1% –3%, kigahinduka ukurikije ubwoko bwamakara nikirere cyaho. Indangagaciro zisumbuye zirashobora kuba zikwiranye n’amakara menshi cyane abikwa mu turere twumutse, umuyaga.
Gutakaza Agaciro Agaciro
Iyo amakara ahuye numwuka, pyrite ikorana na ogisijeni nubushuhe, byongera ubushyuhe bwibigega kandi bigatera ibintu bihindagurika guhunga. Iyi nzira ntisubirwaho.
Kubika amakara bifunze birashobora kugabanya igihombo cyagaciro hafi 300-500 kcal / kg. Ku makara yumuriro afite agaciro ka 5.500 kcal / kg, ibi bihwanye na 5% –9% byagaciro kayo.
Ibi bihombo ntibigaragara kubitabo byapimwe. Nyamara, iyo amakara aguzwe ukurikije agaciro ka calorificateur, bihindura muburyo bwinjiza.
Ubushuhe hamwe nogukoresha ibikoresho
Amazi yimvura yinjira mububiko bwamakara arashobora kongera ubuhehere ku gipimo cya 2-33. Ibi birashobora gukurura urunana rwibibazo bikora: kugabanya ibicuruzwa biva mu mahanga, kugabanuka k'umukandara wa convoyeur, amakara yahagaritswe mu gihe cy'itumba no gukora neza. Ku makara yoherezwa mu mahanga, ubuhehere burenze bushobora no kuvamo kugabanywa ibiciro cyangwa ibihano byamasezerano.
Kubahiriza ibidukikije: Ibyo abashinzwe kubika amakara bakeneye gusuzuma
Inzego enye zo kugenzura ivumbi
Kuva hasi kugeza hejuru, ibiciro bisanzwe byo kugenzura ivumbi birimo:
- Gutera amazi hamwe nibikoresho bikora
- Umuyaga uhuha hamwe no gukuramo umukungugu
