| description | The performance of mist eliminator in wet desulfurization system is critical to the flue gas emission level of coal-fired power plants. Appropriate analysis method should be adopted to analyze the liquid droplets carried in the flue gas of desulfurization. In this paper the impacting method was used to study the droplet size distribution in flue gas of wet desulfurization. The sampling principle, operation manual, data analysis and processing of impact method are introduced. The application examples and precautions in the testing process of impact method are also put forward. The results show that by using the microscope to observe and count the imprints of droplets carried by flue gas on the impact plate, the distribution of droplet size can be obtained according to the diameter and number of the imprint. At the same time, the mass concentration of droplets in flue gas can be calculated as well. Hence corresponding data support is provided from the derived calculation result for the research and optimization of the operation of the demister. |
