Agglomerates growth characteristics in fluidized bed liquid-solids coexistence region
摘要
Abstract
Fluidized bed agglomerates were generated by the TEB atomization nozzle,the sizes of original particles,nucleation agglomerates,coherence agglomerates,paste agglomerates were distinguished by the cascade screening method,and different agglomeration stages could be identified. The most stable heterogeneous agglomerates coexistence region was taken as the research object to analyze the structural and textural characteristics in the growth process. Nucleation agglomerates was the basic element inducing coherence agglomerates. Adhesive growth of agglomerates was accompanied by increased porosity. With the injection liquid continuously filling the pores, agglomerates were gradually saturated. Adhesive growth rates of agglomerates of any size in the coexistence region were the same. In spite of the same fluidization conditions of agglomerates in the coexistence region,moisture contents and solids volume fractions of nucleation and coherence agglomerates were obviously different.关键词
