Abstract

the fluid flow in the selective catalytic reduction (SCR) system of a 600MW power plant was simulated and optimized with a wide variety of duct configuration evaluated; certain configuration parameters such as the location and number of guide plates as well as size of AIG(ammonia injection grid) nozzle were modeled and studied numerically under various load. It is shown that the deviation of NH3 concentration is reduced at the entrance to catalyst after optimization, the flow field and distribution of ammonia can be improved with certain arrangements comparing with the original design.
