摘要： A gas diffusing nozzle device for a fluidized bed furnace having high thermal resistance and durability especially in a high-temperature environment and capable of being manufactured at a low cost, fluidizing a fluid layer uniformly using a fluidized gas jet with a low pressure loss and controlling the flow rate of the fluidized gas jet at the outer circumferential and central portions of the interior of a retort (11) in an arbitrary and individual manner. This device is provided with a circumferential gas supply pipe (19), a central gas supply pipe (24), and a circumferential gas diffusing nozzle section (14) and a central gas diffusing nozzle section (15) respectively connected to these two gas supply pipes. Each of the gas ' diffusing nozzle sections has a plurality of nozzle pipes (16b, 22) with a plurality of downwardly directed fluid gas ejection ports (17) formed in the lower surfaces thereof, and at least one ring-shaped nozzle pipe (16a, 21) joined to the free ends of these nozzle pipes.

摘要： A method of attaining a uniform flow in an elongated fluidized bed furnace, used for the purpose of preventing the expansion and uniting of bubbles in the fluidized bed, and setting the fluidized bed in a uniform flow state, so as to keep the flow condition of the bubbles excelent at all times. The purpose of this method can be achieved by withdrawing a fluidization gas from an arbitrary portion of a fluidized bed (13) through a fluidization gas venting means (A).

摘要： This invention relates to an ejector apparatus of a fluidized bed heat-treating furnace for performing heat-treatment of a work A put into a fluidized bed (2) by circulating an exhaust gas at the upper layer portion of a retort (1) driven by a compressed gas and enclosing therein the fluidized bed (2) from the bottom of the retort (1) to its inside so as to cause fluidization of the fluidized bed (2). The main body (5a) of an ejector (5) consists of at least three members (7, 8, 9), and at least two systems of compressed gases are supplied to contracting portions (8d, 9d) from compressed gas inlets (12,15) defined between the ejector members (7, 8, 9) through gaps formed between the ejector members (7, 8, 9). The gap of each ejector member (7, 8, 9) can be adjusted suitably by adjusting means (F, G). Therefore, the absorption efficiency of the ejector (5) can be freely adjusted over a wide range. Since a centre rod of a prior art apparatus does not exist, the ejector (5) has a simple structure as a whole and is moreover compact.
