Teknisk område Nærværende opfindelse angår et affaldsforbrændingsanlæg omfattende en ovn med en rist, hvorpå affaldet, som afbrændes, transporteres fra affaldstilgangen til askeafgangen.TECHNICAL FIELD The present invention relates to a waste incineration plant comprising an oven with a grate on which the waste which is incinerated is transported from the waste access to the ash disposal.

55

Sidevæggene, som forløber langs risten, omfatter en slidzone i form af et fluidkølet panel placeret umiddelbart i tilstødning til risten og den øvre vægzone over slidzonen er tilvejebragt i form af ildfast beklædning.The side walls extending along the grate comprise a wear zone in the form of a fluid-cooled panel located adjacent to the grate, and the upper wall zone above the wear zone is provided in the form of refractory lining.

10 Kendt teknik I forbrændingsanlæg af denne art er det kendt at tilvejebringe en sådan slidzone i form af fluidkølede paneler placeret umiddelbart i tilstødning til risten, idet slidzonepanelet er placeret hovedsageligt horisontalt langs risten og omfattende en fleksibel tætning imellem slidzonepanelet og den vertikale ovnvæg, som strækker sig over slidzone-15 panelet. Yderligere har den øvre vægzone været beskyttet imod for høje temperaturer ved at have perforerede vægkakler i den nævnte øvre vægzone ved positioner, som er udsat for den mest intensive forbrændingszone på risten, og køleluft tilført igennem de nævnte perforerede vægkakler. Imidlertid har disse perforerede vægkakler en tendens til at tilstoppes og revne, hvilket fører til nødvendig tidlig udskiftning af de nævnte 20 kakler.Prior Art In incinerators of this kind, it is known to provide such a wear zone in the form of fluid-cooled panels located adjacent to the grate, the wear zone panel being positioned substantially horizontally along the grate and comprising a flexible seal between the wear zone panel and the vertical furnace wall which extends. say over the wear zone-15 panel. Further, the upper wall zone has been protected from excessive temperatures by having perforated wall tiles in said upper wall zone at positions exposed to the most intense combustion zone on the grate, and cooling air supplied through said perforated wall tiles. However, these perforated wall tiles tend to clog and tear, leading to necessary early replacement of the said 20 tiles.

Omtale af opfindelsenDisclosure of the Invention

Det er formålet med nærværende opfindelse at tilvejebringe et affaldsforbrændingsanlæg af den ovenfor nævnte art, hvori det er muligt at beskytte den ildfaste 25 beklædning i den øvre vægzone imod forhøjede temperaturer uden de ovennævnte problemer med tilstopning og tidligt slid af de perforerede kakler, og dette formål opnås med et affaldsforbrændingsanlæg af den nævnte art, som i overensstemmelse med nærværende opfindelse også omfatter det træk, at det fluidkølede panel er forsynet med åbninger, hvorigennem kølegas indføres med henblik på at reducere den 30 termiske belastning af den øvre vægzone. Med dette arrangement indføres kølegassen igennem åbninger i det fluidkølede panel og føres sammen med de brændende gasser langs sidevæggene opad, hvorved de køler den øvre vægzone og tilvejebringer en buffer imellem flammerne over det afbrændte affald og den nævnte øvre vægzone.It is the object of the present invention to provide a waste incinerator of the kind mentioned above wherein it is possible to protect the refractory cladding in the upper wall zone from elevated temperatures without the aforementioned problems of clogging and premature wear of the perforated tiles, and for this purpose. is achieved with a waste incinerator of the kind which, in accordance with the present invention, also includes the feature that the fluid-cooled panel is provided with openings through which cooling gas is introduced to reduce the thermal load of the upper wall zone. With this arrangement, the cooling gas is introduced through openings in the fluid-cooled panel and, together with the burning gases, along the side walls upwards, thereby cooling the upper wall zone and providing a buffer between the flames over the burnt waste and said upper wall zone.

Beskrivelse af den foretrukne udførelsesformDescription of the preferred embodiment

Sidevægssektionen i en affaldsforbrændingsanlægsovn vist i fig. 1 omfatter et fluidkølet panel 5, som er placeret umiddelbart i tilstødning til risten 2.The side wall section of a waste incinerator furnace shown in FIG. 1 comprises a fluid-cooled panel 5 located immediately adjacent to the grate 2.

20 Det fluidkølede panel 5 er sammensat af et antal hovedsageligt horisontale rør 10 til cirkulation af kølefluidet, idet de hovedsageligt horisontale rør 10 er indbyrdes forbundet med finner 9 med henblik på at tilvejebringe en massiv væg i slidzonen. Et antal åbninger 7 er tilvejebragt igennem det fluidkølede panel 5 ved positioner imellem rørene 10, dvs. i finnerne 9, som indbyrdes forbinder rørene 10, hvorved kølegas kan 25 indføres igennem disse åbninger 7. På den side af det fluidkølede panel 5, som er modsat ovnkammeret, er der anbragt en manifold 11 for tilførsel af kølegas til åbningerne 7.The fluid-cooled panel 5 is composed of a plurality of substantially horizontal pipes 10 for circulating the cooling fluid, the substantially horizontal pipes 10 being interconnected with fins 9 to provide a solid wall in the wear zone. A number of openings 7 are provided through the fluid-cooled panel 5 at positions between the tubes 10, i.e. in the fins 9, which interconnect the pipes 10, whereby cooling gas 25 can be introduced through these openings 7. On the side of the fluid-cooled panel 5 opposite the furnace chamber, a manifold 11 is provided for supplying cooling gas to the openings 7.

| Kølefluidet, som cirkuleres i det fluidkølede panel 5 er fortrinsvis kedelvand.| The cooling fluid circulated in the fluid cooled panel 5 is preferably boiler water.

3030

Som det kan ses i fig. 2, kan separate manifolder 11 være tilvejebragt for separate sektioner i den hovedsagelige horisontale retning af det fluidkølede panel 5, hvorved individuel tilpasning af tilførslen af kølegas kan tilvejebringes. Som det ses i fig. 1, er åbningerne 7 i finnerne imellem rørene i det fluidkølede panel 5 anbragt i en 35 hovedsagelig vertikal del af det fluidkølede panel 5 og en øvre skrå del 8 af det i DK 176970 B1 3 fluidkølede panel 5 ovenover de nævnte åbninger 7 forløber i retning mod den ildfaste beklædning 6 i den øvre vægzone 6 over slidzonen 7.As can be seen in FIG. 2, separate manifolds 11 may be provided for separate sections in the substantially horizontal direction of the fluid-cooled panel 5, allowing individual adjustment of the supply of cooling gas. As seen in FIG. 1, the openings 7 in the fins between the tubes of the fluid-cooled panel 5 are arranged in a substantially vertical portion of the fluid-cooled panel 5 and an upper inclined portion 8 of the fluid-cooled panel 5 above said openings 7 extending in the direction against the refractory lining 6 in the upper wall zone 6 above the wear zone 7.

Ved denne konstruktion forhindres en eventuel flydende slagge i at løbe ned langs det 5 fluidkølede panel 5 og tilstoppe åbningerne 7 deri. Åbningerne 7 kan naturligvis være tilvejebragt enten som cirkulære åbninger eller slidser eller en vilkårlig anden geometrisk form for åbning. Med henblik på at lette fremstillingen foretrækkes det, at åbningerne 7 tilvejebringes i form af cirkulære huller.In this construction, any liquid slag is prevented from running down the fluid cooled panel 5 and clogging the openings 7 therein. The openings 7 can, of course, be provided either as circular openings or slots or any other geometric form of opening. For ease of manufacture, it is preferred that the apertures 7 be provided in the form of circular holes.

10 Med henblik på at sikre den ovennævnte undgåelse af blokering af åbningerne 7 med flydende slagge, er åbningerne 7 placeret i den vertikale del af det fluidkølede panel 5 | og antallet af kølerør 10 ovenover de nævnte åbninger 7 er fortrinsvis større end tre.10 In order to ensure the aforementioned avoidance of blocking the liquid slag openings 7, the openings 7 are located in the vertical part of the fluid-cooled panel 5 | and the number of cooling pipes 10 above said apertures 7 is preferably greater than three.

Med henblik på at være i stand til at styre strømningen af kølegas igennem åbningerne 15 7 kan en strømningsmåleindretning være tilvejebragt, eventuelt i form af adskillige sådanne måleindretninger, én for hver af de separate manifolder 11 for tilførsel af kølegassen. Yderligere vil det naturligvis være passende at tilvejebringe en eller anden form for styring af mængden af kølegas, som leveres til hver af manifolderne 11, idet styringen eventuelt tilvejebringes i afhængighed af passende målte parametre, 20 såsom målte temperaturer i forskellige positioner i ovnen 2, mængden af affald, som forbrændes i anlægget, etc.In order to be able to control the flow of cooling gas through the openings 15 7, a flow measuring device may be provided, optionally in the form of several such measuring devices, one for each of the separate manifolds 11 for supplying the cooling gas. Further, it will, of course, be appropriate to provide some form of control of the amount of cooling gas supplied to each of the manifolds 11, the control being optionally provided depending on appropriately measured parameters, such as measured temperatures at various positions in the furnace 2, the amount of waste incinerated in the plant, etc.

Kølegassen kan tilføres fra luftblæseren for sekundær-luft, hvorved kølegassen er atmosfærisk luft og således tilføres via de nævnte åbninger 7 i stedet for eller 25 supplerende til sekundær-luft, som tilføres via sekundærluftdyser. Tilførslen af sekundær-luft via sekundærluftdyser er velkendt inden for den kendte teknik for affaldsforbrændingsanlæg.The cooling gas can be supplied from the secondary air air blower, whereby the cooling gas is atmospheric air and thus supplied via the said openings 7 instead of or 25 in addition to secondary air supplied via secondary air nozzles. The supply of secondary air via secondary air nozzles is well known in the prior art for waste incineration plants.

En anden mulighed for tilførslen af kølegas kan være, at benytte recirkuleret røggas 30 udtaget eksempelvis umiddelbart før skorstenen, eller andetsteds i affalds-forbrændingsanlæggets røggasbehandlingssystem, hvor røggassen har en passende lav temperatur med henblik på kølegassens køleformål. Anvendelsen af recirkuleret røggas reducerer eller eliminerer risikoen for at forøge forbrændingen og således temperaturen ved indføringen af kølegas.Another possibility for the supply of cooling gas may be to use recycled flue gas taken out, for example, immediately before the chimney, or elsewhere in the waste incinerator's flue gas treatment system, where the flue gas has a suitably low temperature for the cooling purpose of the cooling gas. The use of recycled flue gas reduces or eliminates the risk of increasing combustion and thus the temperature of the introduction of cooling gas.
