teraction of heat transfer, drying and thermochemical processes in a hearth furnace floor (C03)

C3考察了对流、辐射、接触传热和颗粒运动对热厚颗粒干燥的综合影响。在底炉中，颗粒位于圆盘上。颗粒在圆盘的外围进入炉膛，然后由粗糙的手臂输送到圆盘中心的出口。通过对流（溢流、通流）、辐射（电辐射加热器）和接触（电加热盘）提供热量。实验将从具有各向同性特性的硅胶制成的球形颗粒开始。浸湿的颗粒中掺杂了一种对湿度敏感的颜色指示器，并用摄像机和红外摄像机记录下来。C3将提供独特的数据集，可以在DEM/CFD模拟的背景下验证颗粒力学、传热和干燥。

C3 examines the combined effect of convection, radiation, contact heat transfer and particle motion on drying of thermally thick particles. In hearth furnaces particles are located on a disc. The particles enter the hearth at the periphery of the disc and are then transported by rabble arms to an outlet in the centre of the disc. Heat will be provided by convection (overflow, throughflow), radiation (electrical radiant heater) and contact (electrically heated disc). Experiments will start with spherical particles made of silica gel with isotropic properties. The wetted particles, which are doped with a humidity sensitive colour-indicator, are recorded with a video and an infrared camera. C3 will deliver unique data sets which allow to verify particle mechanics, heat transfer and drying in the context of DEM/CFD simulations.
