Title (EN) A METHOD FOR MONITORING A FLUIDIZED BED
(FR) PROCEDE POUR SURVEILLER UN LIT FLUIDISE
Abstract: front page image
(EN)A method for monitoring the condition of the fluidized bed in a fluidized bed boiler, for monitoring the content of coarse material in the fluidized bed (6). In the method, e.g. the temperature (T2) of the upper part of the fluid­ized bed (6) as well as the temperature (T1) of the lower part of the fluidized bed (6) are determined, and the change in the difference between said temperatures (T1, T2) is monitored. Furthermore, the invention relates to a system for monitoring the condition of a fluidized bed (6) in a fluidized bed boiler, as well as a fluidized bed boiler comprising a system for monitoring the condition of a fluidized bed.
(FR)L'invention concerne un procédé pour surveiller l'état du lit fluidisé d'une chaudière à lit fluidisé, à savoir pour surveiller la teneur en matière grossière du lit fluidisé (6). Selon ledit procédé, on détermine, par exemple, la température (T2) de la partie supérieure du lit fluidisé (6), ainsi que la température (T1) de sa partie inférieure, et on surveille les modifications de la différence entre lesdites températures (T1, T2). L'invention concerne en outre un système pour surveiller l'état d'un lit fluidisé (6) dans une chaudière à lit fluidisé, ainsi qu'une chaudière à lit fluidisé comprenant un système pour surveiller l'état du lit fluidisé.
