The Emperor's Palace was popular, and the footwear there was uniformly distributed throughout the country.
The temperature distribution is uniform, → 1, it is advantageous in terms of countermeasures against book separation, and it is excellent with 9 points as many as Banmeiden, and it is a recent Solft 5! From the point of view of heating efficiency, the hearth is designed as a greenhouse with no electricity cut off, so as the amount of I increases, both sides of the hearth increase. I'll come. Therefore, when using a fluidized bed with a single plane bed, a boiler spring flow occurs due to the bed structure and the installation area constraints, and it is difficult to make a big change, and in the end, the fluidized bed is divided and stacked. Efforts were made to develop a fluidized bed using a way stack structure.

Due to the relationship between stacking individual pieces, a bridge (1) is constructed, and straight partition walls m, c,...
Figure 1 shows the fluidized bed placed on one side and a common flow path for air gas installed in it. (6) is arranged as follows: combustion chamber I on the - floor, combustion chamber I on the second, third, and - floor @

The central firing chamber (2) also serves as a common flow path (1) for the firing gas.

)Kllllllary. In this O structure, as the ped pressure O increases, the gas flow velocity of the distant island (I) increases due to the increase in the combustion gas Oi & released from the fluidized bed at the top, and from a design point of view, The gas flow velocity at the top of the floating bird is suppressed to a certain value. Therefore, the gas flow velocity at the bottom of the common flow path is luck (bottle),! There is a risk that drawings for Dowa would result in a wasteful design.

The flow-bed boiler has a fluidized bed structured like O, and the *m of the fluidized bed decreases to an intermittent hook as it gets to the upper layer, and the 40" eTo has many passageways. , Hall I
II and Figure 8, the flow path expands by 1%/% for the fIA gas O- stationary, whereas in the Kujoji Boitz shown in Figure 8, the flow path expands to 1%/%. I'm not happy about the fact that the speed of a single tower is so limited when expanded.
