Description
Summary:In coal-fired power plants, approximately 5% of sewage sludge solid fuel mixed with coal is used as power generation fuel for environmental protection and global warming prevention. The co-firing method needs a sewage sludge solid fuel crusher that can crush sewage sludge solid fuel to generate a fine powder. This study aims to determine the size of the rotor perpendicular plate hole that can minimize accumulation of the crushed fuel in the roller type sewage sludge solid fuel crusher to be used in the co-firing method. The range of the design parameters for optimization of the rotor perpendicular plate hole is selected and make an orthogonal array table according to design of experiments. The CFD is performed to analyze effect of design parameters according to an orthogonal array table. In addition, the dimension of the rotor perpendicular plate hole that can minimize accumulation of the fuel inside the crusher is drawn using the Multi-objective optimization method.
