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.

Modelling of large-scale dense gas–solid bubbling fluidised beds using a novel discrete bubble model [PDF]
In order to model the complex hydrodynamic phenomena prevailing in industrial scale gas–solid bubbling fluidised bed reactors and especially the macro-scale emulsion phase circulation patterns induced by bubble–bubble interactions and bubble coalescence,

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 ...

Experimental investigation of woody and non-woody biomass combustion in a bubbling fluidised bed combustor focusing on gaseous emissions and temperature profiles [PDF]
Air staging is a well-known effective method to control NOx emissions from solid fuel combustion boilers. However, further research is still needed to clarify the effect of air staging at different injection locations on the gaseous emissions of ...

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.
