A Methodology for Measuring the Heat Release Efficiency in Bubbling Fluidised Bed Combustors
Differences in the densities of bed material and—especially biogenic—solid fuels prevent an ideal mixture within bubbling fluidised bed (BFB) combustors. So, the presence of fuel particles is usually observed mainly near the surface of the fluidised bed.

Bubbling Gas Fluidised Beds As Chemical Reactors
This paper is based on a lecture given on 27 April 1977 to the Chemical Society of Zurich. It describes the principal physical features of a bubbling gas fluidised bed and how these affect performance of the system when it is used as a gas/solid ...

CFD-simulation of gas-solid flow in bubbling fluidized bed reactor [PDF]
The hydrodynamic behaviour of gas-solid flow has been studied in a two-dimensional bubbling fluidized bed reactor filled with particles of 275 µm in size, using computational fluid dynamics (CFD).

Air distribution is the primary factor that influences the performance of fluidized beds. To understand the hydrodynamics and operation of a fluidized bed, an assessment of the airflow and its distribution is essential.

Tailored Syngas Production from the Gasification of Biogenic Waste in the Presence of a CO2 Sorbent
Syngas production via steam gasification is one of the thermochemical processes with the greatest potential for obtaining synthetic fuels from a solid fuel, especially indirect gasification in a dual fluidised bed system where the energy needed for ...
