Solid-State Power Combining for Heating Small Volumes of Mixed Waste Materials
نویسندگان
چکیده
Microwave heating of waste results in chemical breakdown that can lead to conversion mixed materials fuel. Heating mixtures with microwave energy rather than incineration faster and therefore be more efficient. Here we address small volumes food widely differing temperature-dependent electrical properties. Uniform is accomplished mode mixing within a loaded cavity by spatial power combining solid-state amplifiers (SSPAs). We present comparison two circuit-combined spatially-combined 2.45 GHz 70-W 65% efficient GaN SSPAs controlled relative phase. The efficacy shown improve volumetric inside the loading. temperature changes several locations for common are investigated compared FEM electromagnetic simulations, as well FDTD multi-physics simulations incorporate thermal dependence material approach scalable volume power, demonstrated simulation 1.4 L 5.2 volume.

A soft-sphere discrete particle model was used to simulate mixing behavior of solid substrate particles in a slow rotating drum for solid-state fermentation. In this approach, forces acting on and subsequent motion of individual particles can be predicted. The (2D) simulations are qualitatively and quantitatively validated by mixing experiments using video and image analysis techniques. It was ...
