Definitions

  • the present invention relates to the field of fuel additives, in particular, to an additive for solid hydrocarbon fueled burners, furnaces and flames to enhance efficiency and/or reduce undesirable emissions, such as pollutants.
  • Solid hydrocarbon fuels such as coal
  • Coal particularly lignite and other low BTU coals, does not burn very efficiently and generates considerable smoke, NOx, SO 2 , particulate matter and other undesirable emissions including CO.
  • Chemical compounds have been used as combustion improvers to enhance combustion efficiency, of solid fuels.
  • many of these additives contain heavy metallic elements such as manganese, zinc, iron, copper, cerium, calcium and barium. On burning, some of these elements can produce heavy metal solid residues, which are highly undesirable.
  • a fuel additive that includes a combustion catalyst to reduce smoke and particulate emissions from coal fired burners, furnaces and other direct-fired applications would be advantageous.
  • a fuel additive that increases efficiency and/or decreases pollutants for coal and other solid fuels including low quality coal such as lignite, used in these applications would be particularly advantageous.
  • R would also be advantageous to reduce smoke, particulate and nitrogen-containing emissions from fuel applications.
  • reduction or elimination of other toxic pollutants, such as SO 2 are highly desirable.
  • An additive that does not result in the formation of heavy metal precipitates and residues during the combustion process would be desirable. Summary of the Invention

  • One preferred embodiment includes adding these components, in the presence of water, to create the phosphorus-containing parent solution as an aqueous parent solution.
  • the water acts as the solvent.
  • Other preferred parent solution solvents include alcohols.
  • Another group of preferred cations would be the alkali metals or Group IA elements. While NH 4 used as Y creates a fuel additive that enhances fuel performance, there are instances when it is preferred to avoid ammonium and thereby ammonia altogether.
  • Another preferred embodiment of the phosphorus-containing parent solution includes the addition of [NH 4 J 2 HPO 4 to the [Y] x H 2 PO 4 , [Y] x+ HPO 4 , and water.
  • Yet another embodiment includes the addition of NH 4 C 2 H 3 O 2 where C 2 H 3 O 2 " ion is an acetate group such that the solution contains [Y] x H 2 PO 4 , [Y] X+ HPO 4 , [NH 4 ] 2 HPO 4; NH 4 C 2 H 3 O 2 and water.

  • orthophosphoric acids have been described, also called phosphoric acids, this includes pyrophosphoric acids, which are the condensed analogs of orthophosphoric acid.
  • the PO 4 3 becomes P 2 O 7 2" or other condensed phosphates. Therefore, [Y] x H 2 PO 4 , and [Y] X+ HPO 4 are precursors to pyrophosphoric acids.
  • the use of the pyrophosphoric and other condensed forms is therefore encompassed within the definition of the orthophosphate form.
  • the phosphorus-containing parent solution can be applied directly to the solid fuel in any manner capable of producing a uniform coating, such as spraying, dipping, slurring or the like.
  • a uniform coating such as spraying, dipping, slurring or the like.

  • the phosphorus containing parent solution can advantageously be included with this water spray.
  • other methods known in the art to contact an aqueous solution with the solid hydrocarbon can also be used.
  • the fuel additive of the invention is useful to enhance combustion such that more complete combustion is achieved with increased combustion to CO 2 and H 2 O as compared to the combustion of the solid fuel without the fuel additive.

  • the result of adding the additive to the solid hydrocarbon fuel is an enhanced fuel that has a substantial amount of solid hydrocarbon fuel suitable for combustion, and an amount of the fuel additive operable to enhance combustion.
  • the enhanced fuel contains phosphorus in an amount operable to reduce emissions upon combustion of the enhanced fuel as compared to the combustion of the hydrocarbon fuel without the fuel additive. More preferably, the enhanced fuel contains phosphorus of between about 1 and 150 ppm by weight. Another preferred embodiment is between about 1 and 80 ppm by weight.
  • the fuel additive can be introduced onto the coal prior to burning, onto fly ash prior to a secondary burning or can be injected into the fluidized bed or partially fluidized bed during the combustion process by means known in the art.
  • An alternate embodiment of the invention includes a process for enhancing fuel performance of a hydrocarbon fuel in a combustion system including the steps of adding a chemical addition composition to the hydrocarbon fuel in an amount effective to enhance fuel performance.

  • KH 2 PO 4 , K 2 HPO 4 , [NH 4 J 2 HPO 4 and water are created into the phosphorus containing parent solution.
