摘要： PURPOSE:To make possible uniform coal supply and to prevent a heating pipe from corrosion by a method wherein coal is supplied to a premixing fluidized bed to overflow mixture with fluid medium beyond the upper edge of the partition board into the main fluidized bed. CONSTITUTION:Grains of coal supplied from a coal feeder 10 into a premixing fluidized bed is mixed fully with fluid medium. The fluid medium is supplied by a fixed amount from a fluid medium supply pipe 11, mixture of coal and fluid medium that are fully mixed is overflowed always by a fixed amount over the partition board into the main fluid bed 7 to burn coal in a fluid state. Fluid medium containing ashes is exhausted from the ashes exhaust port 12. This amount of exhaust is brought under control in the manner that the amount of the coal overflowing the partition board and that of the admixture of the fluidized medium are made equal. Thus, the main fluidized bed is kept constant in its height, it is mixed sufficiently by the premixing fluidized bed to make the atmosphere uniform in concentration in the main fluidized bed and to prevent the corrosion of the heat transfer pipe.

摘要： PURPOSE:To eliminate a necessity of doubly installing an air carrying equipment and a spreader equipment and simplify the control system by enabling to predetermine the ratio between the quantity of a coal fuel to be supplied to air conveyance and the quantity of a coal fuel to be supplied to the spreader system. CONSTITUTION:Coarsely pulverized coal is sent to a hopper 2 and sieved by first classifying means 3 and coarsely granulated coal is supplied to a conveyor 5. The coals are then stored in a coarsely granulated coal bunker (A) and sent to a feeder 8 each time in a required amount, and dispersed and supplied onto a fluidized layer 10 and burnt. On the other hand, the coarsely grnulated coal is sieved by second classifying means 11 and divided into coarsely granulated coal and finely granulated coal. The finely granulated coal is stored in a finaly granulated coal bunker (B), and the finely granulated coal is supplied to the bunker (A) or (B) by changeover means 14 and stored therein. The fuel in the bunker (B) is supplied into the fluidized layer 16 by an air conveyor pipe 15, and burnt.

摘要： PURPOSE:To prevent a harmful gas of one fluidized bed from flowing into the other fluidized bed, in sending a fluidized substance in one fluidized bed to the other fluidized bed by gravity, by making the pressure of the other fluidized bed side higher than that of one fluidized bed side. CONSTITUTION:A fluidized bed type regenerating furnace 1 of a used desulfurizing agent and a fluidized bed type cooler 2 of the regenerated desulfurizing agent are connected by a connecting pipe 3 having an angle of inclination theta larger than the angle of repose of a fluidized substance and this substance is transferred by gravity. That is, the used desulfurizing agent thrown and supplied into the regenerating furnace 1 from a throwing-in pipe 4 is burnt at about 1,000 deg.C to regenerate CaO and this regenerated CaO is sent the cooler 2 to be recovered from an emitting pipe 5 while cooled to about 300 deg.C. In this case, the pressure P2 of the connecting pipe part in the side of the cooler 2 is made higher than the pressure P1 of the connecting pipe part in the side of the regenerating furnace 1 to send air in the cooler 2 into the regenerating furnace 1 in a proper amount. By this mechanism, a harmful gas generated in the regenerating furnace 1 is prevented from being supplied into the cooler 2.

摘要： PURPOSE:To efficiently remove hydrogen chloride, to separately burn unburnt gas and unburnt particles and to prevent the abrasion and corrosion of a pipe by providing a cyclone to a lower stage gasifying furnace to separate the gas from the furnace into unburnt gas and unburnt particles and supplying the unburnt gas to the wind box of an upper stage combustion furnace by an ejector. CONSTITUTION:A cyclone 13 is provided to the upper part of a lower stage gasifying furnace 12 to separate the gas from the furnace into unburnt gas and unburnt particles. The unburnt gas is supplied to an upper stage combustion furnace 14. An ejector 15 is provided between the cyclone 13 of the lower stage gasifying furnace 12 and the wind box 33 of the upper stage combustion furnace 14 to almost adjust the pressure of the free board of the upper stage combustion furnace 14 and that of the unburnt gas conduit from the cyclone 13 to atmospheric pressure. By this constitution, hydrogen chloride generated from a chlorine compd. in waste refuse is removed and the abrasion and corrosion of the heat transfer pipe in a fluidized bed and the heat transfer pipe on the downstream side thereof are prevented.
