Abstract

Based on inevitability analysis of Tuyere coal and Raceway coke combustion numerical simulation, this paper retrospects previous study and summarizes two phase turbulent flow numerical model of pulverized coal and air, pyrogenation and radiation transmit-heat numerical model of pulverized coal volatile ash, combus- tion energy equation of coke grain. The authors put forward a new idea of boundary condition using CCD tech- nique.
