Abstract

Methods and systems for clean-up of hazardous spills are provided. In some aspects, there is provided a system for burning an water-oil emulsion that includes an enclosure configured to hold a water-oil emulsion; one or more conductive rods disposed throughout the enclosure, each rod of the one or more roads having a heater portion to be submerged in the water-oil emulsion and a collector portion to project above the water-oil emulsion, wherein the collector portion is longer than the heater portion; and a delivery system for supplying an water-oil emulsion to the enclosure, the delivery system is configured to maintain a constant level of the water-oil emulsion in the enclosure as the water-oil emulsion is burned. The enclosure may further include one or more adjustable air inlets.

First claim

What is claimed is:

1. A system for burning a liquid comprising:
an enclosure configured to hold a liquid to be burned;
a plurality of heat conductive rods disposed throughout the enclosure, each rod of the plurality of the heat conductive rods having a heater portion to be submerged in the liquid and a heat collector portion to project above the liquid; and
a delivery system for supplying the liquid to the enclosure.

2. The system of claim 1 wherein the liquid comprises a liquid fuel or an emulsion of a liquid fuel.

3. The system of claim 1 wherein the plurality of the heat conductive rods have an adjustable height.

4. The system of claim 1 wherein a ratio of a length of the heat collector portion to a length of the heater portion is between 2 and 6.

5. The system of claim 1 wherein a height of the rods is between 25% to 75% of a baseline flame height.

6. The system of claim 1 wherein the plurality of the heat conductive are distributed among a plurality of zones, with rods in a same zone having same height and rods in different zones having different height.

7. The system of claim 5 wherein the height of the rods increases toward a center of the enclosure.

8. The system of claim 5 wherein the zones are concentric to one another.

9. The system of claim 1 wherein the enclosure further includes one or more inlets.

10. A method for burning a liquid comprising:
supplying a liquid to be burned to a holding enclosure to a pre-selected level, the enclosure having a plurality of heat conductive rods disposed therein, each rod of the plurality of heat conductive rods having a heater portion to be submerged in the liquid and a heat collector portion to project above the liquid; and
igniting and burning the liquid from the enclosure while maintaining the pre-selected level of the liquid in the enclosure.

11. The method of claim 10 wherein the liquid comprises a liquid fuel or an emulsion of a liquid fuel.

12. The method of claim 10 wherein a ratio of a length of the heat collector portion to a length of the heater portion is between 2 and 6.

13. The method of claim 10 wherein a height of the rods is between 25% to 75% of a baseline flame height.

14. The method of claim 10 wherein the plurality of heat conductive rods are distributed among a plurality of zones, with rods in a same zone having same height and rods in different zones having different height.

15. The method of claim 14 wherein the height of the rods increases toward a center of the enclosure.

16. The method of claim 10 wherein the enclosure further includes one or more inlets.

17. The method of claim 16 , wherein each of the one or more inlets includes a cover mechanism to adjustably change the shape of the inlet.

18. The method of claim 10 further comprising preheating the plurality of heat conductive rods before igniting the liquid.
