摘要:
Oxy-fuel conditions may have a considerable influence on the cement production process. This paper presents the results of a first validation work aiming to model the combustion behavior under rich CO2 conditions. The experiments took place in a 500 kWth pulverized fuel combustion rig. A swirl burner is employed to stabilize an air and an oxy-fuel case (29% oxygen in combustion gases). Detailed measurements of temperature and concentrations (O-2, CO2, CO) along the furnace length are used to validate the simulation work. A commercial CFD software (Ansys Fluent) is employed to simulate both air and oxy-fuel cases. The results from the simulations indicate a good agreement with the measured values. However, some discrepancies are observed in near burner region that may be also be related to the measurement method employed. (C) 2017 The Authors. Published by Elsevier Ltd.
