Microbeam recently launched a new project, “Managing Slag Flow Behavior in Combustion and Gasification Systems” (Tools II), toward advancing methods to predict slag-flow behavior in high-temperature slagging combustion and gasification systems. The project sponsors include the North Dakota Industrial Commission (Lignite Energy Council) and industry.
This project involves integrating the chemical and physical processes involved in slag formation and flow behavior into a three-dimensional computation fluid dynamics (CFD) framework. The CFD will utilize key information derived on high-temperature partitioning of fuel impurities between slag and gas-phase entrained vapors and particles to predict slag layer formation, ash/char retention in slag, slag layer thickness, slag freezing, and slag flow.
The CFD modeling efforts will be used to develop relationships that can be utilized on a day-to-day basis to predict slag behavior as a function of fuel properties, system design, and operating conditions. Current CFD modeling efforts of slag-flow behavior are based on bulk ash composition and do not consider ash partitioning (vapors and liquid/solid particles), ash/char particle retention in slag, chemical and physical properties of slag, and slag layering.
This project advances the findings of Microbeam’s completed “Optimization Tools to Manage Coal Properties and Plant Operations” (Tools I) project which developed improved tools to manage lignite properties and plant operations based on measurable lignite properties.
Both projects received funding through the Lignite Research Fund (administered through a partnership between the Lignite Energy Council and the North Dakota Industrial Commission).
