Abstract
The present invention is directed to pyrotechnic aerosol fire suppression compositions that burn rapidly, but coolly. The rapid burning of the compositions of the present invention produces a voluminous flame-suppressive aerosol that is useful in suppressing and/or extinguishing both small and large fires. The compositions of the invention contain at least one oxidizer and a fuel component comprising at least one organic acid salt, which combination produces a rapid burning composition that burns at low temperatures with little or no flame and have a low heat of combustion.
Claims18
A pyrotechnic aerosol fire suppression composition comprising:
- an oxidizer represented by the formula M(XOx)y, wherein M is selected from a Group IA atom, a Group IIA atom, and a Group IIIA atom, X is selected from the group consisting of Cl, Br and I, x is 1-4, and y is 1-3;
- and
- a fuel component comprising melamine cyanurate, a Group IA or Group IIA salt of an organic acid, or a mixture thereof;
- and
- wherein the oxidizer is present in a greater amount by weight percent than the fuel component, and wherein the composition has a heat of combustion of between about 250 calories per gram and 600 calories per gram;
- wherein the combustion products consist essentially of about 8 percent to about 12 percent H2O, about 15 percent to about 25 percent CO2, about 1 percent to about 10 percent nitrogen, about 40 percent to about 55 percent potassium bromide, and about 18 percent to about 25 percent potassium carbonate by total weight of the combustion products.
A pyrotechnic aerosol fire suppression composition comprising:
- an oxidizer represented by the formula M(XOx)y, wherein M is selected from a Group IA atom, a Group IIA atom, and a Group IIIA atom, X is selected from the group consisting of Cl, Br and I, x is 1-4, and y is 1-3;
- and
- a fuel component comprising melamine cyanurate, a Group IA or Group IIA salt of an organic acid, or a mixture thereof, and
- wherein the oxidizer is present in a greater amount by weight percent than the fuel component, and
- wherein the combustion products consist essentially of about 9 percent to about 11 percent H2O, about 18 percent to about 22 percent CO2, about 2 percent to about 12 percent nitrogen, about 45 percent to about 50 percent potassium bromide, and about 18 percent to about 22 percent potassium carbonate by total weight of the combustion products.
A pyrotechnic aerosol fire suppression composition consisting essentially of:
- an oxidizer;
- and
- a fuel component comprising at least one organic salt, wherein the oxidizer is present in a greater amount by weight percent than the fuel component,
- wherein the combustion products consist essentially of about 5 percent to about 15 percent H2O, about 10 percent to about 30 percent CO2, about 0.5 percent to about 15 percent nitrogen, about 40 percent to about 90 percent potassium bromide, and about 10 percent to about 30 percent potassium carbonate by total weight of the combustion products.
