Agglomeration in fluidized beds at high temperatures: Mechanisms, detection and prevention
TL;DR: A review of the current research status of this topic in terms of agglomeration mechanisms, detection and counteraction strategies can be found in this paper, where a range of detection methods are comprised of fuel ash analysis and analysis methods based on on-line process measurements, such as pressure and temperature.

Size segregation of binary mixture of solids in bubbling fluidized beds
TL;DR: The fluidization behavior of binary mixture differing in size in the gas bubbling fluidized bed is experimentally and theoretically studied in this paper, where the segregation phenomena are analyzed, and the relevancy of the pressure drop profile of the binary mixture to the definition of its minimum fluidization velocity is discussed.

Simulation and experiment of segregating/mixing of rice husk–sand mixture in a bubbling fluidized bed
TL;DR: In this paper, the fluidization behavior of rice husk-sand mixture in the gas bubbling fluidized bed is experimentally and theoretically studied, and the relevancy of the pressure drop profile of Rice husk particles to the definition of its minimum fluidization velocity is discussed.

CFD simulation of bubbling fluidized bidisperse mixtures: Effect of integration methods and restitution coefficient
Carla Tagliaferri,Luca Mazzei,Paola Lettieri,Antonio Marzocchella,Giuseppe Olivieri,Piero Salatino +5 more
TL;DR: In this paper, the authors focused on the role of both restitution coefficient and integration methods on the dynamics of the bed, adopting a mixture of solids assorted in size (with constant density) as case study.

Combustion characteristics of cotton stalk in FBC
TL;DR: In this article, the mixing and combustion characteristics of cotton stalks with 10-100mm in length in FBC were investigated, and it was found that the high alkali metals content causes the formation of the coating around silica sand particles.

The minimum fluidisation velocity, bed expansion and pressure-drop profile of binary particle mixtures
TL;DR: In this paper, the total bed pressure drop, the pressure-drop profile, bed expansion and bed voidage have been measured for a variety of binary particle mixtures over a wide range of gas velocities.

Fluidised binary mixtures in which the denser component may be flotsam
TL;DR: Some experiments are reported which show that in certain special cases this density rule is broken, and the concept of segregation maps is introduced as a convenient way of showing for a particular set of conditions whether small dense particles are jetsam or flotsam, or whether the whole system is well mixed.

Temperature profiles in a lignite flotsam-rich fluidized bed
TL;DR: In this article, the lignite flotsam-rich type segregation patterns were investigated for changes in Lignite type, bed materials, particle size, fluidization velocity and static dynamic bed heights.
