THE BEHAVIOR OF GAS FLOW EJECTED FROM TWO VERTICAL NOZZLES IN A FLUIDIZED BED

摘要

1 INTRODUCTIONIt has been generally accepted through industrial practices and laboratory experi-mentations that chemical reaction in a gas fluidized reactor takes place primarilyat the location within a few centimeters from its bottom.This is particularly no-ticeable for fast reactions.It has been known that under normal operating condi-tions in gas-solid fluidized reactors,the characteristics of bubble size and bubblemovements play important roles in affecting the mass transfer and contacts between
