    摘要: The invention has its object to arbitrarily adjust an amount of particles to be circulated without changing a flow rate of a gasification agent to thereby enhance gasification efficiency in a fluidized bed gasification furnace.The fluidized bed gasification furnace 107 comprises first and second chambers 113 and 114 in communication with each other in a fluidized bed 105. The hot particles 102 separated in the separator 104 and raw material M are introduced into the first chamber 113. The particles 102 introduced from the first chamber 113 through interior in the fluidized bed 105 to the second chamber 114 are supplied in an overflow manner to the fluidized bed combustion furnace 100. A first pressure controller 121 is provided to control the resultant gas induction means 116 such that the pressure in the first chamber 113 is kept to preset pressure 120; and a second pressure controller 124 is provided to control the exhaust gas induction means 118 such that difference between pressure in the first and second chambers 113 and 114 is equal to the preset differential pressure 123, so that the fluidized bed 105 in the first chamber 113 is controlled in height to control an amount of particles 102 to be circulated.

    摘要: A loop seal for a fluidized bed reactor comprising a vertical downcomer segment connected to a dipleg for receiving solids particles from the dipleg, a horizontal segment downstream of the downcomer, a riser segment downstream of the horizontal segment, and a downwardly inclined segment downstream of the riser, whereby the solids are entrained to the fluidized bed reactor. An eductor is added to the angled leg to induce the underflow gas from the cyclone; one of the preferred motive fluids to the eductor is the fines from fuel preparation and the carrying gas for the fines. Also provided are a fluidized bed reactor comprising the loop seal, and a method for producing syngas from coal and steam using the same.

    摘要: 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.

    摘要: A moving bed heat exchanger (155) includes a vessel having an upper portion (200), a lower portion (210) with a floor (272) including a discharge opening therein, and an intermediate portion (205). The vessel directs a gravity flow of hot ash particles (140) received thereby from the upper portion (200) through the intermediate portion (205) to the floor (272) of the lower portion (210) of the vessel, where the hot ash particles (140) are collected. Tubes in the intermediate portion (205) of the vessel direct a flow of working fluid in a direction substantially orthogonal to the direction of the gravity flow of the hot ash particles (140) through the intermediate portion (205) of the vessel such that heat from the hot ash particles (140) is transferred to the working fluid thereby cooling the hot ash particles (140).
