    Abstract: A pyrolysis apparatus comprises a furnace (1) operating by fluidized bed combustion, a pyrolyzer (4) and flow paths, which connect the furnace (1) and the pyrolyzer (4) for arranging the circulation (C) of carrier material of the fluidized bed combustion between the furnace and the pyrolyzer .The apparatus also comprises a supply inlet (14) for supplying fuel to be pyrolyzed to the pyrolyzer (4), fluidizing gas supply means (5) arranged in the pyrolyzer for fluidizing the mixture of carrier material and fuel, and an outlet (6) for taking condensible gaseous substances separated from the fuel to be pyrolyzed out of the pyrolyzer (4), and a condenser for condensing the condensible gaseous substances. The carrier material circulation is arranged at the furnace (1) by a cocurrent principle along the flow path of hot flue gases, which comprises a separator (3) located higher than the pyrolyzer (4), which separator is arranged to separate carrier material from flue gases, while the circulation also comprises a connecting conduit (11) between the separator (3) and the pyrolyzer (4) for moving the carrier material by gravity to the pyrolyzer (4), and a return path (12) between the pyrolyzer (4) and the furnace (1) for returning the carrier material to the furnace (1). The outlet (6) is arranged in the chamber formed by the pyrolyzer (4) in its upper part in a space above the fluidized mixture of carrier material and fuel in order to remove the condensible gaseous substances from the pyrolyzer.

    Abstract: To raise or lower the operating temperature of a fluidised bed to a desired level, the operating temperature of a second fluidised bed is raised or lowered to a temperature above or below that of the desired level and bed material is transferred between the two beds to bring the operating temperature of the first bed to the desired level. The first bed may be an incinerator and to lower the operating temperature the bed material of the second bed is cooled by a fluid in a heat exchanger and material is transferred between the two beds. The transfer of bed material may be brought about by a pump or one bed may be caused to overflow into the other with a corresponding counter-flow of bed material through a duct connecting the two beds.

    Abstract: An internal recycling type fluidized bed boiler includes a primary fluidized bed incinerating chamber constructed by an air diffusion plate, and an inclined partition wall provided above a portion of the diffusion plate where the mass flow of the air injected from the diffusion plate is greater than that from another portion so as to interfere with the upward flow of the fluidizing air injected from that portion and deflect it towards the portion above the diffusion plate where the mass flow of gas injected is smaller. A thermal energy recovery chamber is formed between the inclined partition wall and a side wall of an incinerator. The inclined partition wall is inclined by 10.degree.-60.degree. relative to the horizontal and is arranged such that the length of its projection in the horizontal direction is 1/6-1/2 of the horizontal length of the bottom of the incinerator bottom. A method of controlling the above fluidized bed boiler with respect to the amount of thermal energy recovered from the thermal energy recovery chamber includes regulating the amount of air injected from a diffuser in the thermal energy recover chamber, based on demands from the user side utilizing the recovered thermal energy. The amount of fuel to the primary fluidized bed incinerating chamber is controlled based on the temperature in the primary fluidized bed incinerating chamber.
