摘要:Selectivce Catalytic Reduction (SCR) denitrification is the most widely used flue gas denitrification technology for coal-fired power plants due to its excellent comprehensive performance. The key to the denitrification efficiency is the uniform mixing of the reducing agents NH3 and NOX in the flue gas. In this paper, the linear controlled ammonia injection grid, partition-controlled ammonia injection grid and mixed element of type ammonia injection grid are compared. The advantages and disadvantages of various gas flow field uniformity adjustment techniques are analysed. It is pointed out that the mixed element of type ammonia injection grid technology is the main direction of the current ammonia injection technology development. Finally, the future development trend of the ammonia injection mixing device is pointed out.
