Case Study Comparison of Bubbling Fluidised Bed and Grate-Fired Biomass Combined Heat and Power Plants

Chemical Engineering Transactions, 2016
As woody biomass is gaining importance as an energy source for electricity and heat we need to investigate with scientific methodology the main problems that occur with biomass boiler systems.

Bubble Behaviour in Fluidised Beds at Elevated Pressures

Macromolecular Materials and Engineering, 2011
AbstractLow density polyethylene and polypropylene are produced at large scale via the Unipol process. In this process catalyst particles are fluidised with monomer gas and grow into polymeric particles up to a size of 1 mm. The process is operated at 20–25 bar.

Pilot-scale calcination of limestone in steam-rich gas for direct air capture

Energy Conversion and Management: X, 2019
A novel polygeneration concept, which has been proposed recently, comprises a fuel-cell calciner integrated system in order to produce electricity and lime which can be used for direct air capture (DAC) to remove CO2 from the atmosphere.

Experimental study and characterisation of a novel two stage bubbling fluidised bed gasification process utilising municipal waste wood

Fuel Processing Technology
Biomass gasification has increased due to its ability to provide high-temperature heat, making it promising for the decarbonisation of industrial processes.

Performance evaluation of a novel two-stage waste wood gasifier: Influence of steam-to-biomass ratio and in-situ steam generation on tar formation

Fuel Processing Technology
The shift from high-quality woodchips to low-quality feedstocks increasingly shapes biomass gasification. Small- to medium-scale plants face challenges from heterogeneous feedstock and tar formation, with a research gap in producing energetically useable

Propagation of Reaction Between Bubbles with a Gas Burning in a Fluidised Bed [PDF]

Flow, Turbulence and Combustion, 2011
A bubbling fluidised bed reactor has been used for investigating how combustion propagates between bubbles of premixed fuel + air, rising from the distributor towards the surface. Earlier work has shown that when the temperature of the sand gradually rises, the gases first burn in flames above the bed, regime A, then combustion moves under its surface,

Confined fluidised bed porosity in the light of bubbling-bed models [PDF]

Chemical and Process Engineering, 2012
Abstract Based on hydrodynamic data, Kato-Wen and Kunii-Levenspiel bubbling-bed model parameters, supplemented with assumptions characteristic for tested confined fluidised bed, were analysed. The calculated bubble diameters and the bed composition proved essential influence of inter-particle space of packed compacted component onto fluidisation ...
