ABSTRACT

The complex power plant system involves many subsystems such as the fuelhandling system, water-handling system, boiler-combustion system, boiler-combustion-security system, ash-handling system, dust-handling system, steam-generation system, turbine system, and generator system. This project focuses on four subsytems: the boiler-combustion-optimization model, boiler control, steam-temperature control, and boiler-turbine-generator model. Physical principles including energy conservation, momentum conservation, and mass balance are applied to develop the models. In addition, the genetic algorithm (GA) integrated with computational fluid dynamics (CFDs) is used to create a boiler-combustion-optimization model.
