CFD Simulation of Pyrolysis of Lignite in a Downstream Fluidized Bed
(0) This paper works with the CFD simulation of the process of pyrolysis of lignite particles in a downstream fluidized bed, which actually means the particles would fall down from the injection point and escape the furnace from the bottom. The particle track is solved by using the Lagrangian approach, while the flow of the inert gas (nitrogen) is dealt with by the Eulerian approach. The heat transferred from the nitrogen gas to the surface of particle is computed by means of the famous Ranz-Marshall correlation. The chemical reactions are simulated using part of the coal combustion model inserted in the commercial software used.
