はのＮＯｘ乞生じる。This is because at the top of the fluidized bed, the bed material flows violently, and the air bubbles blown up from below coalesce and rise as air bubbles, knocking off the bed material and scattering it.On the other hand, some of the bed material flows The fins are not uniform as a whole because there are some parts that do not match, and as a result, some of the bed material collides with the water vapor pipes and other pipes in the equipment and the walls, causing severe fin abrasion. . In addition, the scattered bed material or ash is carried outside the equipment, resulting in so-called carry and over. Also, because the flow is not uniform, a high temperature area is created in a part of the combustion, resulting in a large amount of NOx.

設けたことを特徴とする流動層反応装置である。In addition, since the flow is not uniform, blow-through occurs in a part of a large-area fluidized bed combustion apparatus, making uniform combustion impossible. This may cause large load fluctuations to the blower in the pressurized air supply system. In addition, in the case of a boiler, etc., it may greatly affect the generation of steam in the internal piping. This invention was made to solve such problems, and this invention Regarding the drawings showing the embodiment, in Figure 2, the bed material is placed in a main body 3 having an air supply section 1 that supplies air to the bed material and a reaction material supply section 2 that supplies a reaction material. This is a fluidized bed reactor characterized by being provided with a vibrating device 4 for vibrating.
