EFEK GAYA ANTAR PARTIKEL DAN DIAMETER PARTIKEL TERHADAP KECEPATAN MINIMUM FLUIDISASI

Irhan Febijanto

Abstract


In this study, the effect of diameter particle and the effect of inter-particle
cohesion force due to liquid bridge formation on the minimum fluidization velocity
in the fluidized bed have investigated. Also the effect of inter-particle cohesion
force on a fluidization condition of the bed has observed by video camera. The
investigation results showed bigger diameter can give higher minimum
fluidization velocity, and stronger inter-particle force can give higher minimum
fluidization velocity, and then make a quality of fluidization of bed lower. Using
with this investigation results, the mechanism of fouling and slagging
phenomena, which are happen in the coal-fired boiler can be explained.
