Effect of Natural Ilmenite on the Solid Biomass Conversion of Inhomogeneous Fuels in Small-Scale Bubbling Fluidized Beds

Energies, 2022
The application of oxygen carriers as alternative bed material in fluidized bed combustion originates from chemical lopping processes. They serve as oxygen transport agents undergoing consecutive redox cycles. Thereby, oxygen carriers can provide surplus

Effect of Bed Diameter on the Hydrodynamics of Gas-Solid Fluidized Beds [PDF]

Iranian Journal of Chemistry & Chemical Engineering, 2010
Effect of scale on the hydrodynamics of gas-solid fluidized beds was investigated in two fluidized beds of 152 mm and 78 mm in diameter.  Air at room temperature was used as the fluidizing gas in the bed of sand particles.

A Simple Analytical Method for Determining Basic Hydrodynamic Characteristics of Hybrid Fluidized-Bed Air-Lift Apparatae

Chemical and Process Engineering, 2017
A simple analytical method for determination of basic hydrodynamic characteristics of hybrid fluidized-bed air-lift devices was presented. These devices consist of two parts: a two-phase air-lift part and a two-phase liquid-solid fluidized-bed part ...

Hydrodynamic Characteristics of a Fluidized Bed with Rotating Distributor [PDF]

, 2007
The performance of a novel rotating distributor fluidized bed is presented. The pressure drop and the standard deviation of pressure fluctuations were used to find the minimum fluidization velocity, Umf, and to characterize the quality of fluidization ...

In-Line Detection of Bed Fluidity in Gas–Solid Fluidized Beds Using Near-Infrared Spectroscopy

Pharmaceutics, 2023
A novel approach was developed to detect bed fluidity in gas–solid fluidized beds using diffuse reflectance near-infrared (NIR) spectroscopy. Because the flow dynamics of gas and solid phases are closely associated with the fluidization state, the ...

Gas-solid magnetically fluidized beds – A review

Powder Technology
This review provides an overview of the development, and research trends in gas-solid magnetically fluidized beds (MFBs). Fluidized beds, introduced in the 1940s, have significantly contributed to advances in chemical engineering and materials science. This paper chronicles the evolution of MFB technology from its inception in the 1960s to its present ...

Particle-fluid dynamics and solid ejection in fluidized beds [PDF]

, 2008
Los flujos multifásicos son, en general, difíciles de modelar. En concreto, los lechos fluidizados burbujeantes son incluso más complejos debido a la presencia de burbujas (aparte de las partículas y de la corriente principal del gas) que aparecen cuando
