A Study of the Combustion One-dimensional Mathematical Model for a Pulverized Coal-fired Boiler Furnace

In order to effectively conduct direct-current pulverized coal combustion and multiphase flow numerical simulation to achieve low NOx combustion coal.Based on the continuum model of establishing a comprehensive framework for considering gas-solid flow,burner combustion and heat transfer in the one-dimensional mathematical model.Application of this model to the one-dimensional pulverized coal-fired boiler furnace and the gas combustion numerical calculation shows that The model can be used effectively for rapid and multiphase flow simulation direct-current pulverized coal combustion process,given a stove drawing a charge main parameters such as the inner temperature,NOx distribution.
