A combustion model connected burnout with chemical dynamics parameters and quantitative study on it are rarely reported. Pulverized coal combustion reaction dynamics parameters are one of necessary important datum of thermal calculation on combustion equipment based on pulverized coal fuel and basic theory study on pulverized coal particle combustion characteristics .With the development of computer science , mathematical model of pulverized coal combustion is being applied to boiler design and operation little by little. This is required to calculate pulverized coal combustion process as accurately as possible, important initial data in the calculation is reaction dynamics parameters, it quantitatively describes reaction ability of coal and gives change rule of reaction ability of different coals with temperature . According to need of HuNan Hua-Yin ZhuZhou power plant’ 2nd alteration project , fifteen conventional coals that they provided and will burn in the power plant’ W flame furnace are studied on conventional industrial analysis、 element analysis 、actual combustion characteristics and slagging characteristics. Adaptation reactions of coals are analyzed, coal ranges selected of better combustion effect in the flame furnace is given. ground is provided for determining burning coals.
