Abstract

trata-se de um método para controlar uma quantidade de injeção de amônia de um sistema de dessulfurização e desnitrificação de carbono ativado. o método inclui: adquirir dados de situação de gás de combustão de entrada, dados de situação de gás de combustão de saída, um valor de um fluxo de gás de combustão de entrada compensado por temperatura e pressão e um fluxo de ar de diluição de amônia, calcular uma primeira quantidade de injeção de amônia para correção com uso de um primeiro modelo de cálculo predefinido, com base nos dados de situação de gás de combustão de entrada, nos dados de situação de gás de combustão de saída, no valor do fluxo de gás de combustão de entrada compensado por temperatura e pressão, no fluxo de ar de diluição de amônia e nos parâmetros predefinidos, e calcular uma primeira quantidade-alvo de injeção de amônia que corresponde à primeira quantidade de injeção de amônia para correção com uso de um segundo modelo de cálculo predefinido. proporciona-se, ainda, um dispositivo para controlar uma quantidade de injeção de amônia de um sistema de dessulfurização e desnitrificação de carbono ativado.It is a method of controlling an ammonia injection amount from an activated carbon desulphurization and denitrification system. The method includes: acquiring inlet flue gas status data, outlet flue gas status data, a value of a temperature and pressure compensated inlet flue gas flow, and an ammonia dilution airflow , calculate a first amount of ammonia injection for correction using a first predefined calculation model, based on the input flue gas status data, the output flue gas status data, the flow value of temperature and pressure compensated inlet flue gas, ammonia dilution airflow and predefined parameters, and calculate a first target amount of ammonia injection that corresponds to the first amount of ammonia injection for correction using a second default calculation model. A device for controlling an ammonia injection amount of an activated carbon desulphurization and denitrification system is also provided.
