Operating Parameters for the Circulating and Bubbling Fluidised Bed Pyrolysis of Biomass

Characteristics of distinct ash flows in a biomass thermal power plant with bubbling fluidised bed combustor

Characteristics of biomass used as fuel and distinct ash flows in a thermal power plant with BFBC (bubbling fluidised bed combustion) technology were studied. An integrated approach involving chemical composition, microscopy analysis, mineralogy, and thermal behaviour were used to characterize the ash. The ashes have a low unburned content, typically below 3 wt.% (dry basis), with higher values...

Biomass gasification with NiO/Olivine catalysts in fluidised bed gasifier

Tar removal from biomass gasification gas is a crucial problem in applying syngas from biomass for its downstream applications. Catalytic biomass gasification has given promising results for tar cracking. A few research groups have investigated the use of olivine for tar cracking [2,3,4,7,8,9,10]. The presence of oxides of iron and magnesium in the mineral olivine give it the ability to crack h...

Catalytic Fast Pyrolysis of Biomass in a Bubbling Fluidized Bed Reactor with Gallium Promoted Zsm-5 Catalyst

Investigation of the Effects of Introducing Hydrodynamic Parameters into a Kinetic Biomass Gasification Model for a Bubbling Fluidized Bed

Fluidised bed drying of soybeans.

The fluidised bed drying characteristics of soybeans at high temperatures (110-140 degrees C) and moisture contents, 31-49% dry basis, were modelled using drying equations from the literature. Air speeds of 2.4-4.1 m/s and bed depths from 10 to 15 cm were used. The minimum fluidised bed velocity was 1.9 m/s. From a quality point of view, fluidised bed drying was found to reduce the level of ure...
