Abstract

Abstract A method for reducing the emissions of sulfur dioxide and sulfur trioxide in exit gases resulting from the burning of sulfur bearing fuels, which includes the step of igniting at least a member selected from the group consisting of alkaline earth metal nitrates, alkali metal nitrates and ammonium nitrate simultaneously with the igniting ofthe fuel. The method provides for the burning of high sulfur content fuels while maintaining strict environmental emission requirements established for lower sulfur content fuels.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 55 words
A method of reducing the sulfur content of exit gases resulting from combustion.of sulfur bearing fuels or like products, said method comprising the step of igniting the sulfur bearing fuel in the presence of at least one member selected from the group consisting of the alkaline earth metal nitrates, alkali metal nitrates and ammonium nitrate.
Claim 2
Independent Claim 55 words
A method of reducing the sulfur content of exit gases resulting from combustion.of sulfur bearing fuels or like products, said method comprising the step of igniting the sulfur bearing fuel in the presence of at least one member selected from the group consisting of the alkaline earth metal nitrates, alkali metal nitrates and ammonium nitrate.
Claim 3
Dependent Claim 23 words
A method as claimed in claim 1, wherein a mixture of the sulfur bearing fuel with said at least one member is ignited.
Claim 4
Dependent Claim 18 words
A method as claimed in claim 1 or 2, wherein the alkaline earth metal nitrate is calcium nitrate.
Claim 5
Independent Claim 24 words
A method as claimed in claims 1-3, wherein a mixture of calcium nitrate and ammonium nitrate is ignited together with the sulfur bearing fuel.
Claim 6
Dependent Claim 20 words
A method as claimed in claim 4, wherein the mixture represents a double salt of calcium nitrate and ammonium nitrate.
Claim 7
Dependent Claim 18 words
A method as claimed in claim 1 or 2, wherein the alkaline earth metal nitrate is magnesium nitrate.
Claim 8
Independent Claim 25 words
A method as claimed in claims 3-6, wherein the alkaline earth metal nitrate is placed in solution prior to combining with the sulfur bearing product.
Claim 9
Independent Claim 26 words
A method as claimed in claims 3-6, wherein the alkaline earth metal nitrate is placed in a dispersion prior to combining with the sulfur bearing product.
Claim 10
Independent Claim 25 words
A method as claimed in claims 3-6, wherein the alkaline earth metal nitrate is placed in emulsion prior to combining with the sulfur bearing product.
