Ikhwalithi Enhle Eqinile Eqinile Eshisayo Yokuthengisa Isitofu Esiphezulu

   Lapho izinga lokushisa lifinyelela izinga lokushisa elimisiwe, isilawuli sezinga lokushisa sivala ngokuzenzakalelayo isiphephetha-moya ukuze simise ukuvala okuzenzakalelayo komshini wokuphakela umoya.Uma izinga lokushisa liphansi kunezinga lokushisa elibekiwe, isilawuli sezinga lokushisa sivula ngokuzenzakalelayo isivutheli ukuze siqhubeke nokuletha umoya oshisayo.Idizayini enezingqimba ezikabili yolayini wangaphakathi (igumbi lesibili elibaselwayo liwonga kakhulu amandla) ihlukanisa ikamelo elivuthayo kubhayela endaweni yokukhipha umoya oshisayo, futhi isebenzisa ifeni ukuze ikhiphe izinga lokushisa phakathi kwe-interlayer ukuze izifudumeze.I-soot iphuma eduze noshimula (ukuze umoya oshisayo othunyelwe ekamelweni ungangcoli, uhlanzekile futhi ungokwemvelo), futhi ifeni iphephetha ukushisa kwesemishi iphumele ekamelweni ukuze ifudumale, ekwazi ukubona imisebenzi yokushisisa okuzenzakalelayo, ukunikezwa komoya okuzenzakalelayo kanye nokuvutha okuzenzakalelayo.
