| Abstract: | Presently, the SCR flue gas denitrification projects in thermal power plants are entering into the stage of substantial commissioning services. Unfortunately since then many hidden problems from the process of project implementation have emerged gradually. Regarding the present situation of the flue gas denitrification in thermal power plants, several key technical issues are analyzed and explored based on the summary of present SCR denitrification projects, such as the selection of design parameters, the determination of performance guarantee values, the type selection of catalyst and sootblower, the fluid field design, the ash bucket setup and other related modifications. Finally, corresponding suggestions are provided and solutions to these problems are put forward. |
