| Abstract: | We developed a process model of flame beam transmission using pulverized coal powder and coke combustion in a raceway.We employed a Monte Carlo computation method equation based on charge couple devrce(CCD) target heat flow distribution for radiation heat transfer.We explored the factors impacting radiation transmission.Based on these,a three dimensional reconstruction was analyzed at varying coke particle concentrations.This model provided an effective method to produce on-line monitoring of raceway workin... |
