Evaluation of the minimum velocity of polydisperse bed fluidization compounded of biomass pellets and their mixtures with fine particles of coal

摘要

It turned out that the change graphs of the absolute value of dimensionless amplitude of pressure fluctuations against air velocity can be used to evaluate values of the minimum fluidization velocity of polydisperse bed biomass pellets. An experimental verification is reported on the early predicting index of agglomeration in bubbling fluidized bed of biomass pellets and fine coal particles.
