Parametric sensitivity analysis to investigate heptane reforming in circulating fast fluidized bed membrane reactors

Cfd Analysis of Circulating Fluidized Bed Combustion

In this paper computational analysis of circulating fluidized bed combustion using the fluent software is analysed. This work is concerned about gas–solid two-phase mixtures flowing upwards through the fast beds. The procedures studied are applicable to all types of fluidized-bed boilers. The type of information resulting from various ways of analyzing the pressure and temperature in fluidized ...

Cluster Dynamics in a Circulating Fluidized Bed

A common hydrodynamic feature in industrial scale circulating fluidized beds is the presence of clusters. The continuous formation and destruction of clusters strongly influences particle hold-up, pressure drop, heat transfer at the wall, and mixing. In this paper fiber optic data is analyzed using discrete wavelet analysis to characterize the dynamic behavior of clusters. Five radial positions...

Biomass steam-reforming in a low throughput fluidized bed reactor

This work presents the results from biomass gasification tests in a low throughput fluidized bed membrane reactor (FBMR) and compares them with two-phase model predictions. The operating temperature was decreased to 550C, while an equimolar steam/cellulose ratio was used. The profiles of kinetics limitation and biomass conversion were analysed when a palladium (Pd) membrane for hydrogen separat...

Numerical simulation of biomass fast pyrolysis in fluidized bed and auger reactors

Seeking a clean alternative energy resource is inevitable because of the limited fossil fuel energy resources and greenhouse gas emissions issue. Recently, advances in chemical and fuel processing technologies allow us to convert biomass to energy products with high energy density and value. Fast pyrolysis process is among the promising technologies for converting biomass to bio-oil and combust...
