| description | The demand for industrial wet plume elimination has been rising sharply in the current environmental protection strategy. In this paper the influence of environmental conditions are analyzed quantitatively and comprehensively, such as ambient temperature, ambient relative humidity and air pressure, as well as the flue gas temperature on the degree of superheat, which is the key parameter in wet plume elimination technology. The results show that the degree of superheat decreases exponentially with the increase of ambient temperature or the decrease of air pressure, and increases exponentially with the increase of ambient relative humidity or flue gas temperature. When ambient temperature is above 10 °C, the sensitivity of ambient relative humidity to the degree of superheat is slightly higher than that of ambient temperature. As the fluctuations of air pressure may cause drastic changes of the degree of superheat, the variations of regional air pressure should be taken into fully consideration in the design for different projects. Since the degree of superheat also varies significantly with flue gas temperature, the flue gas temperature should be monitored under strict control in wet plume elimination such that the technical advantages of Cooling &Reheating method could be fully utilized. |
