The objective of this proof-of-concept study is to develop the concept and design of a simple prototype system to directly burn off oil slicks in booms at high efficiencies and with low emissions. The approach uses noncombustible and conductive immersed object to enhance the heat transfer from flames back to the fuel to achieve higher vaporization rates. The proof-of-concept project will be carried out in three phases: Phase I: Small-scale (10 and 25 cm diameter burn pans): Determine how basic material and geometric parameters affect the heat transfer and mass loss rates. Effects of thickness, surface area and void volume of the metal mesh/wool blanket as well as the diameter, pitch, and material of the springs will be measured. Further investigation of the controlling parameters of heat and mass transfer including the height and number of springs will be analyzed. Phase II: Intermediate-scale (70 cm diameter burn pan): Analysis and modeling of the 25 cm pan tests will be used to design the test parameters in Phase II. The data from Phase II will then be used as a guide for designing and conducting the large-scale tests. Phase III: Large-scale (140 cm diameter outdoor burn pan): Experimental tests in a 140 cm pan will be used to evaluate the prototype burner for field use. The concept prototype system will be tested in the USCG's test tank in Mobile, Alabama.
