Predictions of O2/N2 and O2/CO2 Mixture Effects during Coal Combustion using Probability Density Function

抄録

A simulation model has been developed for the entrained flow coal gasification process to investigate the effect of N2 replacement with CO2 during combustion. Both O2/N2 and O2/CO2 gas mixtures were used, with molar fractions of oxygen varying between 10 and 100%. The conventional numerical methods and sub-models used for the pulverized coal combustion have been considered in this modeling. For reacting system, non-premixed combustion model using the Probability Density Function (PDF) for fluctuating scalars (mixture fraction) has been employed. It has been found that the O2/N2 environment gives higher gas temperature than O2/CO2 environment with the same oxygen content. On the other hand, the similar flue gas temperature and char conversion were obtained with oxygen content in the O2/CO2 mixture at about 30%.
