Abstract

Abstract

A more accurate one-dimensional turbulent ignition model of pulverized coal air flow in a tube was established on the basis of the one-dimensional plane laminar flow ignition model. An experimental plat for high temperature air pulverized coal ignition was set up. To test the theoretical model, air heating and pulverized coal ignition experiments were done. The experimental results are in good agreement with the calculated ones. The feasibility of pulverized coal ignition by high-temperature air was proved.
