Fluidized device

Abstract

Abstract PURPOSE: To enable the collection of burnt residue with little unburnt content by a mehtod wherein troubles in a fluidized bed such as adhesion, hardening and formation of clinker are reduced and, the generation of NO x being controlled, the burning efficiency of heavy crude oil is raised. CONSTITUTION: The fluidized air 5 is introduced into a lower fluidized bed 1 through the intermediary of a dispersion plate 6. The heavy crude oil ash is introduced into the lower fluidized bed 1 from a nozzle 7, while additive oil 11 being also introduced into the lower fluidized bed 1 from a burner 10. Then, the heavy crude oil ash and a fluidizing medium subjected to the pre-processing of melting dissolution of the content of ammonium sulfate in the lower fluidized bed 1 rise up to an upper fluidized bed 2. Into the upper fluidized bed 2 introduced the anxiliary air 13 from the primary air nozzles 12. The fluidizing medium extracted from an overflow nozzle 16 provided in the upper part of the upper fluidized bed 2 through the inter- mediary of a rotary valve 17 is supplied to a fluidizing-medium regenerating device, where the ash content stuck to the fluidizing medium is removed.
