State-of-art technology of SCR system for coal fired boiler
More than 18 years have passed since the first SCR systems for the coal fired plant in the world provided by Mitsubishi was put into commercial operation. During the above period, SCR catalyst has been developed to overcome any difficulties which were experienced, especially because the flue gas contains the large amount of dust compared with gas and oil fired unit. For example, dust plugging, SO{sub 2} oxidation rate, pressure loss and erosion have been the main items to be solved. This paper describes the background of the above items and test results which was conducted before the application to the actual unit to confirm the initial performance and the durability against them. In addition to the above, the efforts to reduce the catalyst volume for coal fired unit by means of the application of smaller pitch catalyst is also presented together with the inspection result of smaller pitch catalyst after the operation.
