Two Phase Modeling of Char Combustion in a Circulating Fluidized Bed Reactor Using ASPEN PLUS
In this paper, combustion of char in the riser of circulating fluidized bed was modeled using ASPEN PLUS. Since physical and chemical phenomena are involved in the process, the model integrates the two-phase hydrodynamic sub-model with the reaction sub-model derived from the literature. In the proposed model, the fluidized bed is divided into several sections and the behavior of each section wa...
متن کاملOn Numerical Resolution Requirements in Combustion Modeling
We discuss one-dimensional steady laminar premixed flames in a mixture of calorically imperfect ideal gases described by detailed kinetics and multi-component transport. The required spatial discretization to capture all detailed continuum physics in the reaction zone is determined through use of a robust method developed to rigorously calculate the finest length scale a posteriori. This is acc...
متن کاملMathematical modeling of a fixed bed chromatographic reactor for Fischer Tropsch synthesis
In this research, Fischer Tropsch synthesis (FTS) has been modeled in the fixed bed chromatographic reactor for the first time by applying a rather complex dispersed plug flow model for fluid phase and linear driving force (LDF) model for adsorbent. Model equations are dynamic, multi-component, non-linear and heterogeneous including reaction and adsorption simultaneously Complex kinetics fo...
متن کاملNumerical modeling of biomass combustion in a stoker boiler
Biomass fuel is considered a promising substitute for traditional fossil fuels. Amid a great variety of methods for converting the energy in biomass fuel into usable energy, direct combustion is still the dominant technology employed by industry. Because biomass fuel possess a much wider range of physical and chemical properties than fossil fuel, its combustion behavior is similarly diverse (an...
