Abstract:In order to solve the problem of low SCR denitration efficiency and catalyst attrition under low temperature conditions, SCR denitration technology with heating method is used to optimize the flue gas mixer, diversion and ammonia injection system through numerical simulation methods, so that the relative standard deviation of velocity, relative standard deviation of concentration, temperature deviation, velocity deflection angle, and pressure drop and so on, meet the design requirement, that is effectively ensuring the denitration efficiency and reducing high-temperature flue gas to erode walls and reducing the erosion of the catalyst surface by flue gas. At the same time, based on the actual operating conditions of the project, the temperature and pressure drop compared with the simulated operating conditions proves the reliability of the SCR denitration technology simulation analysis with heating method. The actual operating results have also been tested by third parties and fully meet the emission requirements.
