摘要：
A system is provided. The system includes an exhaust aftertreatment system configured to treat emissions from a gas turbine. The exhaust aftertreatment system includes multiple ammonia injection grids arranged in multiple stages. Each ammonia injection grid of the multiple ammonia injection grids is configured to inject ammonia into an exhaust flow from the gas turbine. Each ammonia injection grid of the multiple ammonia injection grids is individually tuned to operate with a specific load condition of the gas turbine.
