    摘要: A pneumatically conveyed flow of solids is continuously introduced into a pressurized container (42) in which a fluidized bed is maintained by adding an aerating gas, said bed being heated by heat exchange with a heat transfer medium (58). The mixture of solid/gas is continuously removed from the fluidized bed and separated into a lean gas phase and a highly compressed solid /gas mixture by gravitational or centrifugal deposition. The highly compressed solid/gas mixture is then continuously discharged into a pneumatic conveyor line (221) and conveyed pneumatically. The solid content of the pressurized container (42) is continuously monitored. Via a controlled gas removal (68) from the lean gas phase the continuos discharge of the highly compressed solid/gas mixture into the pneumatic conveyor line (221) is controlled in such a manner that the solid content of the pressurized container (42) remains substantially constant.

    摘要: L'invention concerne un dispositif d'échange thermique comprenant un premier échangeur thermique (ET1) suivi d'un deuxième échangeur thermique (ET2) disposé dans un lit fluidisé dense, ce deuxième échangeur étant constitué d'une pluralité de faisceaux tubulaires (F1, F2, F3) disposés le long du trajet des particules en suspension dans le lit fluidisé dense.
    Le deuxième échangeur (ET2) comportant au moins deux alimentations situées de part et d'autre de son centre, ces alimentations reçoivent chacune un mélange distinct du fluide d'entrée et du fluide sortie du premier échangeur (ET1), de sorte que la température du fluide entrant dans chacun des faisceaux (F1, F2, F3) soit une fonction croissante de sa distance à l'entrée des particules dans ce lit fluidisé dense.

    摘要: L'échangeur de chaleur comporte au moins un premier (3A) et un second (3B) panneau de tubes montés suspendus dans un caisson. Ces deux panneaux sont juxtaposés dans un plan vertical, le premier panneau de tubes raccordant un premier collecteur d'entrée (4A) d'un fluide disposé en partie basse latérale du caisson (1) à un collecteur de sortie (5) disposé en partie haute centrale du caisson, le second panneau de tubes (3B) raccordant un second collecteur d'entrée (4B) du fluide disposé en partie basse latérale du caisson au collecteur de sortie (5). Chaque panneau comporte des premiers tubes (31) qui s'étendent horizontalement dans la partie basse du caisson, des seconds tubes (32) raccordés aux premiers tubes (31) et qui s'étendent verticalement entre la partie basse du caisson et la partie médiane du caisson, et des troisièmes tubes coudés (34) raccordés aux seconds tubes (32) et qui s'étendent entre la partie médiane du caisson et la partie haute du caisson. Cette disposition permet d'obtenir une grande surface d'échange thermique pour un encombrement réduit de l'échangeur. Cet échangeur de chaleur est destiné à être installé dans un lit dense externe équipant un foyer à lit fluidisé circulant.

    摘要: Heat exchanger consisting of a reservoir with upwardly directed tubes through which flow a liquid to be heated and fluidized bed particles for internally cleaning the tubes. Connected to the reservoir is an external downcomer (5) for collecting fluidized bed particles coming from the top box of the reservoir and to be transported back to the bottom box (7) of the reservoir. The connecting line (4, 2, 1, 3, 6) between downcomer (5) and bottom box (7) is designed as two sections (2, 3) with an expansion bellows (1) arranged between them. The bottom section (3) is connected via two or more connecting stubs (6A, 6B) with the bottom box (7) for the uniform distribution of the flow of fluidized bed particles.

    摘要: The present invention refers to a method of regulating the steam superheating temperature in a circulating fluidized bed type gas cooler. Hot gas is introduced into a mixing chamber, where it is mixed with solids having a temperature lower than that of the gas, whereby the temperature of the mixing chamber settles to a mixing temperature. The mixture of the gas and solids is taken from the mixing chamber via a riser to a solids separator, heat being thereby cooling the mixture of gas and solids and transferring heat to heat transfer surfaces. Solids are separated from the gas in the separator and recirculated into the mixing chamber. In connection with the cooling of the gas, superheated steam is generated in evaporators and superheaters arranged in the cooler. The mixing temperature in the mixing chamber, according to the invention, is utilized for temperature regulation of the superheated steam generated in connection with the gas cooling. The mixing temperature may be regulated by controlling the amount and temperature of solid material being introduced into the mixing chamber.
