Description

  

      Verfahren    zum Vermindern störender Wirkungen von Verbrennungsprodukten.    Die     Erfindung    bezieht sich auf ein Ver  fahren zum Vermindern störender     Wirkun-          gen    von Verbrennungsprodukten, die bei der  Verbrennung     vanadiumhaltiger    Brennstoffe  in einer Brennkammer entstehen, mittels  eines spätestens nach der Verbrennung den  Verbrennungsgasen zugesetzten phosphorhal  tigen Zusatzes.  



  Es wurde gefunden, dass die störenden       Wirkungen    der sich bei der Verbrennung  bildenden Produkte, darunter insbesondere  des sieh bildenden     V205,    wesentlich vermin  dert werden können, wenn Phosphor bzw.       P..,0;;    oder diese enthaltende Verbindungen  während oder nach der     Verbrennung        aznve-          send    sind. Anscheinend wird das     V205    durch  Bildung von Phosphorverbindungen so fest       gebunden,        class    nicht nur der Dampfdruck  geringer wird, sondern auch die katalytische  Fähigkeit für Oxydationen stark     zuriiekgeht.     



  Die Menge des Zusatzes an phosphorhal  tigen Stoffen richtet sich nach der Menge  an     V205;    ein     Molverhältnis    von 3 :1 bis 1 :5  ist vorteilhaft..  



  Allerdings kommt es bei alleinigem Zusatz  von Phosphor bzw. phosphorhaltigen Verbin  dungen in den meisten Fällen zur Bildung  störender Ablagerungen; man hat daher bis  her die Verwendung von Ölen mit phosphor  haltiger Asche vermieden. Diese Ablagerun  gen treten aber nicht auf, wenn gleichzeitig  entsprechende Mengen von Stoffen, welche  bei der Verbrennung feinverteilte feuerfeste  Verbindungen liefern, oder von fein verteil-         tem        Si02,        A1203    usw., während oder nach  der     Verbrennung    zugefügt werden.

   Diese  Stoffe haben die Aufgabe, die     geschmolzenen     Anteile - meist Natriumsulfat plus V205     -f-          P205    - aufzunehmen, sei es     adsorptiv    oder  durch Reaktion bzw.     -Glasbildung,        und    damit  die     Ablagerung    zu verhindern. Die Menge  dieser Zusätze beträgt etwa das     lOfache    der       P205-Menge.    Ein im Verhältnis zum Kiesel  säurezusatz zu hoher     P205-Gehalt        bringt    un  erwünschte Ablagerungen.  



  Die Zugabe von Phosphor bzw. phosphor  haltigen Verbindungen erfolgt am besten in       F'oian    von     Suspensionen,    Emulsionen oder Lö  sungen in Brennöl; so bewährten sich Emul  sionen von Phosphorsäuren und Suspensionen  von rotem Phosphor in Brennöl und Gemische  von Brennöl mit     Trikresylphosphat    usw. Auch  die Zugabe von komplexen     Phosphor-Poly-          kieselsäuren    ist manchmal vorteilhaft.  



  Sämtliche Zusätze können auch als solche  in fein verteilter Form während oder nach  der Verbrennung den Verbrennungsgasen zu  gefügt werden.



      Method for reducing the adverse effects of combustion products. The invention relates to a method for reducing the disruptive effects of combustion products that arise during the combustion of vanadium-containing fuels in a combustion chamber by means of a phosphorus-containing additive added to the combustion gases at the latest after combustion.



  It has been found that the disruptive effects of the products formed during combustion, including in particular the V205 which forms, can be significantly reduced if phosphorus or P .., 0 ;; or compounds containing these are consumed during or after the combustion. Apparently the V205 is bound so tightly by the formation of phosphorus compounds that not only does the vapor pressure decrease, but also the catalytic ability for oxidation is greatly reduced.



  The amount of phosphorus-containing substances added depends on the amount of V205; a molar ratio of 3: 1 to 1: 5 is advantageous.



  However, the sole addition of phosphorus or phosphorus-containing compounds results in the formation of disruptive deposits in most cases; the use of oils with ash containing phosphorus has therefore hitherto been avoided. These deposits do not occur, however, if at the same time corresponding amounts of substances, which produce finely divided refractory compounds during combustion, or of finely divided SiO2, A1203 etc., are added during or after the incineration.

   These substances have the task of absorbing the molten fractions - mostly sodium sulphate plus V205 -f- P205 -, be it adsorptively or through reaction or glass formation, and thus prevent deposits. The amount of these additives is about 10 times the amount of P205. If the P205 content is too high in relation to the silica addition, undesired deposits are created.



  The addition of phosphorus or phosphorus-containing compounds is best done in the form of suspensions, emulsions or solutions in fuel oil; Emulsions of phosphoric acids and suspensions of red phosphorus in fuel oil and mixtures of fuel oil with tricresyl phosphate etc. have also proven successful. The addition of complex phosphorus-polysilicic acids is sometimes advantageous.



  All additives can also be added to the combustion gases as such in finely divided form during or after the combustion.
