The focus is on coal combustion; gas-particle-flow and radiation heat transfer in the furnace. The dispersed flow of flue gas has to be modeled because radiation heat transfer gets considerably intensified by the contained coal and ash particles. Customized connectors for the dispersed flow of flue gas had to be developed on the base of Modelica.Fluid.
The component oriented approach supports the adaption of the model to different simulation tasks; such as stability analysis of the evaporator or influence of the coal mill on plant dynamics. Component structure; parametrization and spatial discretization were important aspects for the development of maintainable and re-usable components of the model library.
Keywords: steam power plant; coal; dispersed flow; radiation heat transfer; connectors
