Mutengo wekugadzira girazi une soda ash, marasha, uye zvimwe zvinodhura, imwe neimwe inoverengera chikamu chimwe muzvitatu chemutengo wekugadzira webhizinesi.Mumutengo wekugadzirwa kwegirazi rekugadzira girazi, kunze kwemafuta uye soda ash, zvimwe zvinhu zvine chikamu chidiki uye kushanduka kwemitengo zvakare kwakadzikira.Naizvozvo, mitengo yemafuta uye mitengo yesoda ash ndizvo zvinhu zvikuru zvinokanganisa mutengo wegirazi.
Masvomhu ekutanga anoratidza kuti rimwe nerimwe rinorema bhokisi regirazi rinoyangarara rinodya anenge 10-11 makirogiramu eheavy soda ash, yakaenzana nekugadzira tani imwe yegirazi, inova 0.2-0.22 matani esoda ash;Mutsetse wekugadzira girazi re600 ton/day unoda matani 0.185 emafuta anorema kugadzira toni imwe yegirazi.Heavy soda ash inowanzogadzirwa kubva mumunyu mbishi uye limestone kuburikidza nemakemikari synthesis nzira kugadzira light soda ash, uyezve kuburikidza yakasimba-chikamu hydration nzira kugadzira heavy soda ash.Pamusoro pezvo, inorema yakachena alkali inogona zvakare kuwanikwa ne evaporation kana carbonization uchishandisa yakasikwa alkali seyakabikwa.Zvinoenderana nekugadzirwa kwegirazi rinoyangarara, gasi rechisikigo rinoshandiswa kugadzirwa zvakajairika.Mumoto we600 toni ine mwero wekunyunguduka we0.83, kushandiswa kwemagetsi i65 degrees Celsius uye kushandiswa kwemvura i0.3 tons.Kana zvigadzirwa zvisina kunaka, mutengo wemutengo uchange wakaderera.
2. Girazi=25% caustic soda+33% fuel+quartz+artificial.
Mafekitari egirazi ari munzvimbo dzine quartz dzakawanda, senge Shahe, kuderedza mitengo.
