Numerical Simulation Of Altitude Impact On Pulverized Coal Combustion

摘要：

A drop-tube Furnace simulation model has been developed to investigate the pulverized coal combustion characteristics under different altitudes using the commercially available software Fluent.The altitude conditions of 0m,500m,1000m,1500m have been discussed.The results included the fields of temperature,pressure,velocity,the coal burnout,CO burnout and NO emission in the tube furnace.The variation of these parameters with altitude has been analyzed.The coal combustion characteristics were affected by the altitude.The time and space for coal burnout should be increased with the rise of altitude.The valuable results could be referenced in the design of coal-fired furnaces for the high altitude areas.
