Cfd Simulation Scale-up of a Dual-fluidized Bed Gasifier for Biomass
The University of California in collaboration with West Biofuels, LCC, has developed an advanced thermochemical gasification system (5 ton/day) for the conversion of waste stream biomass for the production of bio-fuels and bio-energy. The “Pyrox” gasifier design is based on a dual-fluidized bed system operating at atmospheric pressure with air. Simulation of this gasifier was conducted with a n...
متن کاملHydrodynamics of a Dual Fluidized Bed Gasifier. Part II: Simulation of Solid Circulation Rate, Pressure Loop and Stability
This paper focuses on the determination of the solid circulation of a CFB gasification system with a dual fluidized bed concept and the distribution of the solid hold up at different fluidization conditions. A mathematical model of the riser was designed and implemented in a model of a dual fluidized bed system. This model contains routines for calculation of each section of the dual fluidized ...
متن کاملThree-dimensional modeling of a circulating fluidized bed gasifier for sewage sludge
A three-dimensional model of a circulating fluidized bed gasifier was developed, which uses continuous radial profiles of velocities and solids hold-up with regard to the description of fluid mechanics. A complex reaction network of sewage sludge gasification is included in the model. In the simulation calculations the influence of the axial location and the number of feeding points was examine...

متن کاملApproximating a Three-Dimensional Fluidized Bed With Two-Dimensional Simulations
Fluidized beds can be used to gasify biomass in the production of producer gas, a flammable gas that can replace natural gas in process heating. Modeling these reactors with computational fluid dynamics (CFD) simulations is advantageous when performing parametric studies for design and scale-up. From a computational resource point of view, two-dimensional simulations are easier to perform than ...
