Abstract: The present invention provides an air-filling cushioning material which can sufficiently inflate cells and, in addition, which can hold the crease of the fold when being formed into a three-dimensional configuration. An air-filling cushioning material 1, in which a plurality of cells 2 having an air-fillable space are formed by adhering overlapped flexible sheets 1a, 1b at predetermined spots wherein one sheet 1a is flat while the other sheet 1b is molded beforehand into a configuration of the cells 2 in inflation at the position where the cells 2 are to be formed. Therefore, there is no such problem, as in the conventional case where the cells are formed by tucking the other sheet, the cells cannot inflate well. The cells 2 formed on the other sheet 1b can inflate sufficiently into a configuration as molded.

Abstract: A circulating fluidized bed reactor is provided, based on a multi-inlet cyclone, comprising an elongated riser channel (5; 25), which has a lower portion (4; 24) and an upper portion, whereby solid matter and fluidization gas can be fed into the riser through the lower portion (4; 24). In the upper portion of the riser channel, there is a multi-inlet cyclone comprising a separation chamber (7; 27), with a set of guide vanes (6; 26), a central tube (8; 28) connected to the separation chamber, an outlet (11; 31) and a return channel (10; 30). The set of guide vanes (6; 26) of the multi-inlet cyclone, the cyclone chamber (7; 27) and the central tube (8; 28) are annularly fitted about the riser channel (5; 25). The configuration of the circulating fluidized bed reactor allows for advantageous flow dynamics and the reactor may be used as a dryer or steam boiler.
