摘要： The invention concerns the design arrangement of the cap for the inlet of fluid into the fluidization bed which is heated or cooled by the methods described in U.S. Pat. Nos. 3,897,546 and 3,908,284. The cap is formed by an inlet pipe closed at its upper end on which are formed two or more mutually separated chambers, while in this pipe a number of holes is drilled for the inlet of fluid into the chambers. Into these chambers a number of holes are drilled for the outlet of fluid from these chambers into the fluidized-bed. The vertical distance of the inlet holes from two neighboring chambers of the cap either equals or is smaller than one and one-half times the height of the heat exchanger situated in the particular fluidization bed formed between these two neighboring chambers of the same cap. The caps were used for the inlet of the combustion air into a fluidized-bed combustor, while the pressure drop of the lower part of the cap did not exceed 10% of the pressure drop of the upper part of the caps.
摘要翻译：本发明涉及用于入流入流化床的流体入口的盖的设计布置，其通过美国专利No. 第3,897,546和3,908,284号。盖由其上端封闭的入口管形成，其上形成有两个或更多个相互分离的腔室，而在该管道中钻出若干孔用于进入腔室的流体入口。在这些腔室内钻出许多孔，用于从这些腔室流入流化床的流体出口。入口孔距盖的两个相邻室的垂直距离等于或小于位于同一盖的这两个相邻室之间形成的特定流化床中的热交换器的高度的一倍半。将盖用于燃烧空气的入口进入流化床燃烧器，而帽的下部的压降不超过帽的上部压降的10％。
