Chemical Mechanistic Approaches for the Suppression of Soot Formation in the Combustion of High Energy Density Fuels.

Abstract

Significant advantages can be gained by the use of high energy density fuels in volume limited applications. However, excessive soot formation that accompanies the combustion of these fuels presently limits their application. Fuel additive approaches prove attractive as they require minimal modifications to already existing equipment. In the present study, a variety of flame configurations were used to study the additive effects on soot formation. Through tests conducted on laminar diffusion flames carbon disulfide (CS2) and methanol (CH3OH) were found to be the most effective soot suppressants. Chemical interaction by either additive was found to far surpass the physical influences. However, the exact nature of the chemical action could not be established with the current set of experiments. Additionally, both of these additives were found to reduce soot formation in at least one high energy density fuel - quadricyclane (C7H8). To further validate this approach, studies were conducted using droplet flames and high-pressure spray flames.
