摘要： The invention relates to the method and equipment for treatment of fuel for fluidized bed combustion, which includes drying, classification and crushing of the fuel. The method for treatment of fuel comprises mixing the fuel with hot ash removed from the fluidized bed combustor and drying said mixture in a fluidized bed dryer in which the velocity of the fluidization fluid equals or is lower than the minimum fluidization velocity of particles in the fluidized bed combustor. The equipment for treatment of fuel comprises a bunker, crusher and dryer, comprising a fluidized bed dryer provided with appropriate piping for interconnection of the fluidized bed dryer, fluidized bed combuster, fuel bunker and crusher.

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％。

摘要： The invention concerns the method of feeding particles at multiple points into a fluidized bed by forming at least one auxiliary fluidized bed of the particles and fluidization fluid from which the particles in fluidized state are introduced through a system of inlets into the main fluidized bed. The invention relates to equipment for performing the method consisting of at least one chamber for formation of the auxiliary fluidized bed including the inlet of solid particles and a grid for the inlet of fluidization fluid, and a chamber for the main fluidized bed including the inlet of fluidization fluid, and a system of inlet pipes by which both chambers are mutually interconnected. The system of inlet pipes has the cross-sectional area smaller than 10% of the horizontal cross-sectional area of the main fluidized bed.
