Investigation of Biomass Combustion and Conceptual Design of The Fluidized-Bed

Abstract

This study investigates the combustion process of empty fruit bunches (EFB) and palm kernel shells (PKS) in a bubbly fluidized-bed combustion chamber. The biomass combustion simulation process uses a kinetic model consisting of chemical kinetic and hydrodynamic flow. This modelling is based on the two-phase theory in the fluidized bed. Where both phases in the bed are assumed that there are a mass and energy transfer between them. These phases include the emulsion phase and the bubble phase which contains solid particles. The constant temperatures throughout the reactor are assumed in this modelling. This study also investigates the parametric and effects of various parameters carried out. The experimental research shows that there is a change in bed diameter and has a negligible effect on combustion performance. The results of biomass combustion experiments with a fluidized-bed design have promising and satisfying results compared to several experimental studies in the literature. In addition, the increase in reactor temperature and a bed height of combustion efficiency also increased. However, the moisture of the biomass and the speed of the fuel entering can affect various for combustion efficiencies. Suitable operating conditions can produce maximum overall efficiency.

An Overview of Polygeneration as a Sustainable Energy Solution in the Future

“…Biomass and coal are the best sources for H and C [195][196][197][198]. Biomass and coal-based polygeneration, synthetic liquids and natural gas fuels can be used as additional output as previously discussed [93,[199][200][201][202]. The output of polygeneration can be sulfur, ammonia, urea chemical fuels, etc., however, this is independent of the synthetic fuel used [60].…”

Experimental Analysis of Dual Inlet Cyclone Separator

“…The particle size and the flow condition in the cyclone has always been in related with the swirl and turbulence in the separation process. The turbulence drives the solid particles to swirl [10][11][12] inside the cyclone and end up in the exit stream [13]. The physical properties such as the inlet velocity of the fluid and viscosity also affect the separation efficiency of a cyclone separator [14].…”
