Modelling of Air and Oxy-fuel Combustion in a Circulating Fluidized Bed
Journal Title: Acta Energetica - Year 2016, Vol 27, Issue 2
Abstract
The paper presents the use of a computer model to simulate the process of fluidization in an industrial boiler at Turów power plant. Air and oxy-fuel combustion was modelled for the study, and the effect of the geometrical model’s simplification on the bulk material distribution in the combustion chamber was examined. Numerical simulations were performed using Ansys FLUENT software enhanced with additional user defined functions that were implemented in the calculation procedure. The computer model allowed for the analysis of the effect of solid phase’s volume fraction in the combustion chamber on the heat exchange between the bulk material and the boiler’s heated surfaces. The computer simulation results showed satisfactory consistence with measured data.
