Effect of ozone on coal combustion

With the principle that ozone generates when air is exposed to strong UV radiation, UV-radiated air flowed into a thermobalance to react with pulverized coal. The thermal analysis method was used to study the effect of ozone on coal combustion. It is showed that small amount of ozone can advance the burning time and the weightlessness time of pulverized coal. Dynamics analysis reveals that ozone decreases the activation energy of pulverized coal combustion reaction. Thermodynamic calculations show that the higher the temperature is, the more easily the oxygen atoms are stimulated by oxygen molecules exposed to UV radiation. The idea is proposed that strong UV-radiated hot blast air flow should be used to increase the combustion efficient of injected coal for a blast furnace.
