I-powder impregnation iveliswa kwinkqubo yokulala ye-fluidized bed. Kwijenereyitha yegesi yeWinkler, ibhedi enolwelo lokuqala yasetyenziselwa ukubola koqhagamshelwano lwepetroleum, kwaza emva koko kwaphuhliswa inkqubo yonxibelelwano enezigaba ezibini, yaza yasetyenziswa ngokuthe ngcembe kwiingubo zentsimbi. Ngoko ke, ngamanye amaxesha kusabizwa ngokuba "indlela yokwaleka ibhedi ene-fluidized". Eyona nkqubo kukongeza umgubo wokugquma emazantsi enkonkxa evuzayo yamanzi (umkhombe wokuhamba), faka umoya oxinzelelweyo osuka kwivuthela, emva koko ugaye ukuze ujike umgubo wokwaleka ube “kwimo ye-fluidization” Yiba ngumgubo ocolekileyo usasazwe ngokulinganayo.
Ibhedi ehlanjululweyo yinqanaba lesibini lokuhamba kwezinto eziqinileyo (eyokuqala yinqanaba lebhedi esisigxina, kwaye okwesibini linqanaba lokuhamba kwegesi). Ngesiseko sombhede osisigxina, qhubeka ukwandisa izinga lokuhamba (W), ibhedi iqala ukwandisa kwaye ikhulule, kwaye ukuphakama kwebhedi kuqala ukunyuka. , Iqhekeza ngalinye elingumgubo. I-E iyadada, ngaloo ndlela ishiya indawo yokuqala ukuze ibe neqondo elithile lentshukumo. Emva koko faka isigaba sokulala esimanzi.
Icandelo le-BC libonisa ukuba i-powder layer kwibhedi edibeneyo iyanda, kwaye ukuphakama kwayo (I) kwanda ngokunyuka kwesantya segesi, kodwa uxinzelelo kwibhedi alunyuki (ΔP). Umbhede owenziwe ngamanzi awuyi kuguqula izinga lokuhamba phakathi koluhlu oluthile, kwaye aluyi kuchaphazela amandla athile afunwa ngumbane. Olu luphawu lwebhedi ene-fluidized, esetyenziselwa inkqubo yokwaleka. Ukufana kwemeko ye-fluidization kwibhedi edibeneyo isitshixo sokufana kwengubo. Ibhedi enolwelo esetyenziselwa ukugquma ngumgubo yeya "vertical fluidization". Inombolo ye-fluidization ifumaneka ngemifuniselo. Ngokuqhelekileyo, inokugqunywa. Izinga lokunqunyanyiswa kwepowder kwibhedi edibeneyo inokufikelela kwi-30% -50%.
