About This Lesson
- Co-firing Biomass with Coal Gasification.
- This project involves the simulation of coal and biomass co-firing in a furnace using CFD techniques.
- The primary objectives are to examine the combustion characteristics and validate the simulation results against the study by Ghenai and Janajreh.
- The furnace is defined with specific boundary conditions, and simulations are performed using an unsteady, incompressible flow model.
- The turbulent flow within the furnace is modeled using the k-e RNG turbulent model, thermal radiation is simulated with the P1 model, and combustion is analyzed with a PDF model.
- The simulation incorporates the kinetics/diffusion-limited rate model for particle combustion and the two competing rates Kobayashi model for devolatilization.
- Results are compared in terms of temperature contours and particle trajectories, confirming the simulation’s accuracy with a maximum error of approximately 5% in particle temperature ranges.
