Research Initiation: A Systematic Investigation of Circulation Fluidized Bed Scale-Up

利用一种具有良好时间和空间分辨率的新型电容探头，可以测量循环床内的轴向和径向固体浓度。该设备的独特之处在于可以使用不同的气体作为流态化介质。这应该允许通过单个冷流设备来模拟大规模的热燃烧室。这项研究将为循环床提供更好的放大程序，循环床是高效、高通量的气固接触的非常有前途的候选者。这种装置可能会被用作下一代的燃煤燃烧器。

Axial and radial solids concentration within circulating fluidized beds will be measured using a new capacitance probe capable of good time and space resolution. The facility is unique in that different gases can be used as the fluidising medium. This should permit the simulation of large scale, hot combustors by a single cold flow facility. The research should provide better scale-up procedures for circulating fluidized beds which are very promising candidates for efficient gas- solid contacting with high throughput. Such devices may be used as the next generation of coal combustors.
