摘要： The present invention relates to a fluidized bed furnace in which by forming a fixed-bed adjacent to a fluidized-bed, wastes are moved together with a fluidized medium onto the fixed-bed by utilizing a splashing action of the fluidized medium in an upper portion of the fluidized-bed, thereby allowing a reaction such as drying and pyrolysis of the wastes to proceed slowly with time, and thus the wastes can be dried and pyrolyzed slowly in the entire furnace. The fluidized bed furnace includes a base plate (30) disposed at a bottom portion of a furnace body (10) and having gas supply ports for supplying a fluidizing gas to fluidize the fluidized medium, and a fluidized bed (20) formed on the base plate (30) in the furnace body (10) to take the wastes into the fluidized medium and pyrolyze the wastes. The fluidized bed (20) has the fixed-bed (23) where the fluidized medium is kept in a resting state, and the fluidized-bed (22), formed adjacent to the fixed-bed (23), where the fluidized medium is fluidized.

摘要： The present invention relates to a process for producing metal oxide from metal com pounds, in particular metal hydroxide or metal carbonate, in which the metal compound is conveyed into a reactor (25) with fluidized bed, heated there to a temperature of 650 15 to 1150°C by combustion of fuel, and metal oxide is generated, as well as to a corre-sponding plant. To improve the utilization of energy, it is proposed to introduce a first gas or gas mixture from below through a gas supply tube (26) into a mixing chamber (20) of the reactor (25), the gas supply tube (26) being at least partly surrounded by a stationary annular fluidized bed (27) which is fluidized by supplying fluidizing gas, and 20 to adjust the gas velocities of the first gas or gas mixture and of the fluidizing gas for the annular fluidized bed (27) such that the Particle-Froude numbers in the gas supply tube (26) lie between 1 and 100, in the annular fluidized bed (27) between 0.02 and 2, and in the mixing chamber (20) between 0.3 and 30.

摘要： A circulating fluidized bed (CFB) boiler includes a reaction chamber, where a bubbling fluidized bed (BFB) is contained within an enclosure within the lower portion of the reaction chamber and contains an in-bed heat exchanger (IBHX) that occupies part of the reaction chamber floor. A plurality of in-bed secondary air nozzles comprise a plurality of tubes which are grouped together and run across the width of the BFB between the BFB enclosure wall and an outside wall of the CFB. The nozzles are positioned to prevent the deflection of solids falling onto the BFB from the CFB by the secondary air jets while avoiding a complicated structure that would interfere with gas and/or solids movement in the furnace. The nozzles' exit openings are flush, or almost flush, with the BFB enclosure wall.

摘要： An internal circulation type fluidized bed boiler in which a fluidized bed primary combustion chamber is formed by providing above the portion of an air distributing plate from which the air having a higher mass velocity is ejected an inclined partition wall which is adapted to intercept an upward flow of the fluidization air ejected from this air ejection portion, and turn this upward flow of the air toward the position above the portion of the air distributing plate from which a gas having a low mass velocity is ejected, with a heat recovery chamber formed between the inclined partition wall and a furnace wall. The inclined partition wall is formed so as to have an angle of inclination of 10°-60° with respect to a horizontal plane, and a horizontal projection length of 1/6-1/2 of the horizontal length of the furnace bottom. The method of controlling this fluidized bed boiler consists of the steps of controlling the quantity of heat recovered from the heat recovery chamber in compliance with the request by the users of recovered heat by suitably regulating the flow rate of the air ejected from a diffuser for the heat recovery chamber, and controlling the feed rate of the fuel supplied to the fluidized bed primary combustion chamber, on the basis of the temperature of the fluidized bed primary combustion chamber.
