Abstract

Gasification is making a strong comeback as a sustainable energy source in clean energy systems such as IGCC, as a renewable source utilizing millions of tons of waste dumped in the landfill, and as a solution to the ground water leaching and CO2 & CH4 emission that risking our ecological system. In this paper, thermodynamic equilibrium and numerical analyses of the gasification of coal and tire crumbs in an entrained flow gasifier is presented. This work seeks to obtain a comparative analysis between the optimum operation conditions for the two feedstocks. The numerical model uses an Eulerian-Lagrangian approach with discrete phase model of feedstock in a continuous model of oxidant. This model also takes into account the turbulent flow (SST k-ω model), gas phase gasification (Species Transport model), tire particles devolatilization (Kobayashi Two-Competing Rate model), heterogeneous char reaction (Multiple Surface reaction model), particle dispersion by turbulent flow (Stochastic Discrete Random Walk model), radiation (P1 model) and particle distribution (Rosin Rammler model). The temperature distribution and product distribution of the developed model is also presented in this paper.
