Bubble Dynamics In A Sand Fluidized Bed In The Presence Of Biomass Pellets, Nicolas Torres Brauer
Bubble Dynamics In A Sand Fluidized Bed In The Presence Of Biomass Pellets, Nicolas Torres Brauer
Electronic Thesis and Dissertation Repository
Given the worldwide concerns regarding fossil fuel availability, global warming, water, and air pollution and economy needs, there is an urgent requirement to develop and implement alternative energies. Biomass gasification can consume vegetal waste to produce syngas, which is a mix of carbon monoxide, hydrogen, and carbon dioxide. When biomass gasification is carried out in a fluidized bed, the process is highly efficient.
The experimental study of the present Ph.D. dissertation took place in a Plexiglas 0.44 m diameter unit, equipped with a CREC Optiprobe system and a video camera. The unit was filled with 200-900 µm sand particles and …

Study Of Motion Of Agglomerates Through A Fluidized Bed, Muhammad Owais Iqbal Bhatti
Electronic Thesis and Dissertation Repository
Formation of agglomerates in Fluid CokersTM can cause operating problems, such as excessive shed fouling, which can lead to premature unit shut down. Better understanding of how agglomerates move through a fluidized bed can help improve the design and operation of Fluid CokersTM and minimize the risk of agglomerates reaching regions where they cause problems.
To identify key factors in agglomerates motion in a fluidized bed, a new two-dimensional (2D) Radioactive Particle Tracking (RPT) method was developed which tracks model agglomerates motion. In conjunction, a tribo-electric method was used to determine bubble flow distribution in the fluidized bed. …
