The combustion behaviour of six emulsions, prepared by CSGI (Center for Colloids and Surface Science) in Florence, was studied in the single droplet combustion chamber. A first series of tests was devoted to study the effect of ageing on the combustion behaviour. Tests were performed on fresh emulsions (within 1 month after preparation) and after 2 months ageing at 20 °C. The emulsions resulted stable with the exclusion of the samples where 15% of water was added. The second series of tests had the aim of studying the combustion properties of emulsions when compared with commercial diesel oil. Independently of emulsions composition, in terms of concentration of oil, surfactant and co-surfactant, as well as the size of the oil droplets in the emulsion, the homogeneous combustion rate resulted identical for emulsions and diesel oil.
