U-Xiye uye wabandakanyeka ngokunzulu kwintsimi yonyango lwegesi ye-flue ephezulu kunye nokuhlanjululwa kwegesi kwiziko lombane iminyaka emininzi, ukuqokelela amava axabisekileyo kunye namava obugcisa kunye nobulumko obusebenzayo. Siye saba yinkokeli ekusombululeni iingxaki ezintsonkothileyo zokucocwa kwerhasi ye-flue ngokuphonononga okuqhubekayo kunye nokutsha kule ntsimi. Iqela leengcali ze-Xiye ngokuqhubekayo liqhekeza imiqobo yobugcisa, liphucula ukuhamba kwenkqubo, kwaye liqinisekisa ukuba yonke iprojekthi inokufezekisa ukulingana okungcono phakathi kokukhuselwa kwendalo kunye neenzuzo zoqoqosho.
Inkqubo yokucoca igesi ngokuzimeleyo ephuhliswe ngu-Xiye iphumelele iziphumo ezibalulekileyo kwiimeko ezininzi zesicelo ezifana nokuveliswa kwe-silicon manganese alloy, ukuveliswa kwe-calcium carbide, kunye ne-ironmaking e-China. Le nkqubo ayinciphisi ngokufanelekileyo kuphela ukukhutshwa kwerhasi eyingozi, iphucula ngokubonakalayo ubunyulu nokusetyenziswa ngokufanelekileyo kwerhasi yamalahle, kodwa izisa neenzuzo ezibalulekileyo zokonga umbane kunye nokunciphisa ukukhutshwa kwerhasi kubasebenzisi, ikhuthaza ngokufanelekileyo inguqu eluhlaza kunye nokuphuculwa kwamashishini anxulumeneyo.
