Definitions
- This invention relates to an incinerator which is utilized for incinerating municipal and industrial wastes and a method for incinerating such substances. More specifically, it is concerned with an incinerator the structure of which with regard to after-burning is improved, and a method for incineration to be conducted in such an incinerator.
- Figure 3 illustrates one example of a known mechanical incinerator.
- substances to be incinerated such as municipal and industrial wastes which are supplied into a hopper chute b of the mechanical incinerator a are introduced into a main stoker c and undergo a primary combustion while the main stoker c rotates.
- the substances burned in the main stoker c are then introduced into an after-burning substoker d which is connected to the downstream end of the main stoker c so as to undergo a secondary combustion therein.
- ashes together with unburned materials and incombustible matters are water-cooled and discharged through a discharging port e connected to the downstream end of the substoker d.
- Numeral f designates a space where firing takes place by firing means, such as burners.
- Figure 3 illustrates another example of the prior art. As shown in figure 3, a main stoker c where a main or primary combustion takes place and a substoker d where after- or secondary combustion takes place are inclined downwardly in sequence.
- a mechanical incinerator a of the above-mentioned type has the following disadvantages.
- the substances contain moisture so that dehydration is necessary in order to more easily handle the substances.
- the object of this invention is to provide an incinerator which is capable of realizing a desired combustion performance without care on operation or special controlling equipments.
- Another object is to provide an incinerator from which ashes are discharged in dried state, and a method therefor.
- Still another object is to provide an incinerator which does not require special preparations or preprocessings such as breaking and crushing of the substances to be incinerated, and which is capable of simplifying a manipulation concerned with combustion.
- Claim 2 describes a preferred further development of the incinerator of claim 1.
- this combustion stoker 3 To the downstream end of this combustion stoker 3 there is connected a fluidized bed incinerator 4 where unburned matters which are already pre-burned in the stoker 3 and carried downstream thereof undergo after-burning.
- the stoker 3 is connected to penetrate the side wall of the fluidized bed incinerator 4 which surrounds and defines the firing space formed in its upper section.
- Said hopper chute 2 and the stoker 3 connected thereto are both inclined downwardly toward the fluidized bed incinerator 4.
- Numeral 6 designates air diffuser tubes for supplying air into the fluidized bed incinerator 4, numeral 7 a discharging mechanism for carrying sand or the like out of the incinerator, and numeral 8 an exhaust port for discharging substances including ashes, incombustible materials and sand.
- substances to be incinerated such as municipal and industrial wastes are introduced into the stoker 3.
- substances to be incinerated such as municipal and industrial wastes are introduced into the stoker 3.
- those substances are ignited at its entire surface and undergo a mechanical pre-combustion.
- ashes are removed through gaps between the water tubes which are separated from each other.
- the unburned substances are agitated and introduced into the fluidized bed incinerator 4 because the stoker 3 is inclined downwardly. Since the inlet opening of the incinerator 4 is located at a high level, the manipulation of combustion is simplified and drawbacks of the conventional incinerator are eliminated.
- this equipment does not require a crane for handling the substances to be incinerated. Furthermore, preparation or pretreatment such as breaking and crushing the substances is not necessary.
- the ash can be discharged in dried state from the incinerator.
- the incinerator of this invention combines the advantages of both mechanical incinerators and fluidized bed incinerators.
