Zowoneka bwino za SGL mndandanda wamadzi woziziritsa wa drum slag ndi:
(1) Sungani ntchito ya slag: kuziziritsa kowuma kumatengedwa kuti mupewe kukhudzana ndi madzi a slag.Pitilizani ntchito ya slag, kuti zinyalala zovutitsa zomwe zimapangidwa ndi chotenthetsera kukhala ntchito yabwino ya simenti ndi zomangira zowonjezera.
(2) High matenthedwe dzuwa, lalikulu kusinthasintha osiyanasiyana kutentha slag kumaliseche (40 ℃ ~ 220 ℃);
(3) Chovalacho chimagwiritsidwa ntchito pozungulira ndi kukankhira zinthu.Palibe kusuntha kwachibale pakati pa tsamba lozungulira ndi silinda.Mapangidwe ake ndi osavuta, makina onse ali ndi moyo wapamwamba, kugwiritsa ntchito mphamvu zochepa komanso phokoso lochepa.
(4) Kutetezedwa kwabwino kwa chilengedwe ndi ntchito zachuma: palibe zofunikira zapadera zamadzi ozizira, madzi ozizira angagwiritse ntchito magetsi ozungulira madzi ozizira kapena madzi ambiri a mafakitale, osafunikira desalting ndi kufewetsa, akhoza kuchepetsa ndalama zogwirira ntchito komanso ntchito.
(5) Kutuluka kwa slag mosalekeza, liwiro likhoza kusinthidwa mosalekeza mumtundu waukulu malinga ndi kuchuluka kwa slag.Ndikopindulitsa kukhazikika kukakamiza kwa bedi la boiler, kusunga makulidwe a gawo la kuyaka kwa boiler, ndikuchepetsa kaboni wa slag.
(6) madzi ozizira kukhetsa chitoliro ndi kunja yamphamvu, kotero wodzigudubuza ndi otetezeka, odalirika ndi zosavuta kusamalira;
(7) Ikhoza kukhala ndi alamu yozizira yamadzi ozizira, Dulani madzi ndikuyimitsa (ndi alamu) 、 mpumulo wowonjezera ndi chitetezo china.
