Abstract

Abstract

A mathematical model of the gas-solid flow and heat transfer in blowpipe of BF oxy-coal injection has been developed by the multi-flow model and turbulence model. Then the velocity and temperature of both gas and pulverized coal as well as its concentration have been calculated in industrial scale blowpipe under different injection conditions. The theoretical predictions are in qualitative agreement with experiments.
