摘要： PURPOSE:To prevent a melt slag from adhering to and solidifying on a grate, and thereby allowing for a continuous operation, while at the same time substantially reducing a fuel cost remarkably by burning and melting from inside a slag layer with the temperature retained by the slag layer. CONSTITUTION:An incineration slag N containing unburned carbons is stacked on a grate 20 and falls towards the inclining direction as a moving layer 11 over the grate. On the other hand, a burning air with an elevated temperature is supplied to an air box 27 via a burning air supply tube 30, and wherefrom to a moving layer through a burning air spousing port 31 defined in the overlapped portion of grate 20, and thereby burning unburned carbons and the accompnaying heat is utilized to melt an incineration ash. An air is thus supplied in a parallel fashion from the lower portion of slag to the moving layer directly. The slag thus can be burnt from its internal portion, radiating less amount of heat. Therefore, a burning heat may be retained in the moving layer so that it may be effectively utilized form melting.

摘要： PURPOSE:To rapidly regulate combustion air blowing amount in response to variations in a flame due to alteration of charging amount of article to be incinerated by imaging the interior of a furnace of a fluidized bed type incinerator, processing the imaged picture, recognizing the size and color of the flame, and regulating the combustion air blowing amount into the furnace on the basis of the recognition. CONSTITUTION:A picture processor 21 recognizes variations in a flame when a large quantity of article to be incinerated is charged from a picture imaged by a television camera 30. When it is input to a computer 22, the computer 22 immediately outputs a control signal to a damper 12 to largely open the damper 12, and opens the closed damper 12 in a predetermined opening. Thus, secondary combustion air blowing amount to be blown into a furnace 1 by a secondary blower 8 is rapidly increased, and part of the primary combustion air fed under pressure by a primary blower 6 is blown as secondary combustion air into the furnace 1, thereby accelerating the combustion of decomposed gas generated in a large quantity.

摘要： PURPOSE:To avoid any possible danger of melting an air nozzle in a combustion zone by operating a pusher immediately when the temperature of a combustion zone rises up to the temperature right after incinerated ashes starts melting and extruding the incinerated ashes which has started melting in said combustion zone up to a melting zone where no air nozzle is installed. CONSTITUTION:A large pusher 12 installed to an end wall on the upper stream side of a furnace body 2 is primarily adapted to mix and transfer incinerated ash 20 in a filling zone 5 and a combustion zone. However, when the temperature in a combustion zone 6 rises to the temperature right after the incinerated ash 20 starts melting, the large pusher 12 operates immediately based on the instruction from 8 pusher controller 15, extending its stroke length from the present position to the melting zone, and extrudes the incinerated ash 20 which has started melting in the combustion zone 6 to the melting zone where there exists no air nozzle 10. Therefore, the incinerated ash 20 can be perfectly melted in the melting zone, thereby preventing the air nozzle 10 located in the combustion zone 6 from the danger of being melted.

摘要： PURPOSE:To perform normally stable high temperature combustion and melting, by a method wherein an unburnt substance remaining in incineration ash is burnt in incineration ash, a content of the unburnt substance is determined from generated melting gas and oxygen concentration, and melting is effected in a way that air feed amount is regulated to a value corresponding to the content. CONSTITUTION:Incineration ash A conveyed in a melting furnace 2 is orderly burnt and melted on a furnace floor part 5. In this case, the temperature of melting gas generated along with combustion and oxygen concentration are detected. From the oxygen concentration, a computing unit 18 calculates an air excess factor (air ratio). From temperature detected based on a relational diagram, a current unburnt carbon content is determined, and an air feed amount corresponding to the unburnt carbon content is determined. An air amount control device 20 regulates an air feed means so that a difference between an air feed amount judged by the computing unit 18 and a detected air amount is eliminated. Thus, an air amount corresponding to a residual unburnt carbon in the incineration ash A is fed to an ash melting furnace 2, which can effect stable high temperature combustion and melting.

摘要： PURPOSE:To provide a stable melting operation without requiring any heating source by a method wherein a required amount of unburnt substance left in combustion ashes by forwarding or retracting it in a transmitting direction in such a way as a complete combustion position of waste material during its transportation enters a proper range and then the remaining unburnt substance is burnt in the combustion ashes. CONSTITUTION:A ratio of inclusion (r) of unburnt carbon in combustion ashes A is calculated in order to get a proper melting operation within an ash melting furnace 2. An inclusion ratio (r) of the unburnt carbon at that time is inspected while supervising a melting condition in the ash melting furnace 2 so as to calculate the desired ratio of inclusion (r). The inclusion ratio (r) of the unburnt carbon and a position of a complete igniting position 12 within a main body 3 of the furnace have a cooperative relation. As a complete igniting point 12 is retracted, i.e. moved toward an upstream side 9 of the transporting operation, the combustion ashes A are exposed more to a flame while its transporting operation, so that an amount of unburnt carbon in the combustion ashes A is reduced and in turn as it may advance to move toward the downstream side 10, its amount is increased. Accordingly, the inclusion ratio (r) of the unburnt carbon in the combustion ashes A can be increased or decreased by moving the burn completing point 12 toward the transporting direction E in an aft and fro direction.

摘要： PURPOSE:To obtain a desired combustion performance and to enable to take ashes out of a furnace in a dry state, by providing a fluidized-bed furnace in order to after-burn pre-burned matter to be incinerated which is burned by a combustion stoker and is gradually led to the side of an after flow. CONSTITUTION:A matter to be incinerated such as city refuse and industrial waste being thrown into the hopper chute 2 of an incinerator 1 is led into a combustion stoker 3 and is mechanically pre-burned, being swirled by a rotating water pipe. The pre-burned matter to be incinerated is gradually conveyed into a fluidized-bed furnace 4 because the combustion stoker 3 is inclined downward. The pre-burned matter to be incinerated which is still in the unburned state, being led into the fluidized-bed furnace 4, is after-burned and is burned completely. Ashes are dried in the fluidized-bed furnace 4 and is taken out of a furnace from a discharge port 8 by a discharger 7.

摘要： PURPOSE:To reduce a ventilating resistance inside a moving layer for thereby facilitating the burning and melting of unmelted ash, by positively draining a melt slag from the moving layer and preventing their induced flow. CONSTITUTION:An incineration slag N containing unburned carbons from industrial waste materials such as an urban refuse burnt is stacked upon a grate 22 inside a melting furnace 11. The slag thus stacked falls towards an inclined, or drainage direction as a moving layer 10, while being pushed by a pusher 14. On the other hand, the moving layer 10 is progressively heated up by the exothermic body 28 of heating means 27 provided at the lower portion of grate, while simultaneously burning carbons, its unburned component, by a burning air supplied thereat from a burning air blow-off port 19. An incineration ash is melted by a burning heat produced during this operation. A melt slag thus produced falls along the grate and is discharged immediately in the direction of gravity, and thereby separating the slag from the moving layer 10. Thus, the slag can be transferred over the grate merely with an unmelted ash being separated, and therefore the contact of unmelted ash with the burning air can be improved. The improvement in burning and melting operation is therefore accomplished.

摘要： PURPOSE:To efficiently melt the residue and to form into slag by a method wherein heat of burnt gas generated in burning treatment process and heat of buring uncombusted carbon in combustion residue is utilized to melt the combustion residue. CONSTITUTION:Solid waste 16 is charged from inlet 2 into the main combustion chamber 16 and is burnt by ignition burner 3 and combustion-air 12 guided from wind box 4 via water pipe wall opening. The combustion residue 17 is guided into the after-combustion chamber 6. The combustion in the chamber 1 is controlled so that unburnt carbon will remain in amount of 7-25%, or preferably 10-20% in the residue 17. The residue 17 gradually falls through the after-combustion chamber 6 in filled-state, meanwhile combustion-air 13 is supplied from air supplier 7 so that the unburnt carbon is burnt and the residue is melted. The melted residue becomes molten slag 18 and is sent to slag cooling tank 8.
