新泻大学提出了一种新型的开窗式粒子流化床太阳能接收器/反应器的概念[1，2]。在反应器顶部有一个透明石英窗的接收器/反应器中，粒子流化床直接受到集中太阳辐射的照射（图1）。集中的太阳辐射向下穿过窗口并直接加热颗粒流化床的上部区域中的颗粒。内循环流化可以通过使气体以更快的流速从底部分配器的中心区域通过来产生，这促进了颗粒从床的顶部到底部的良好传热，以产生通过床的均匀温度分布。
A novel concept of a windowed, particles fluidized bed solar receiver/reactor has proposed by Niigata University [1,2]. A fluidized bed of particles is directly irradiated by concentrated solar radiation in the receiver/reactor which has a transparent quartz window on top of the reactor (Fig. 1). Concentrated solar radiation passes downward though the window and directly heats the particles in an upper region of the particles fluidized bed. The internally-circulating fluidization can be created by passing gas with a faster flow rate from the center region of the bottom distributor, which promotes good heat transfer by particles from the top to bottom of the bed to create uniform temperature distribution through the bed.
