An exemplary embodiment can be an exemplary method, which can include, for example, generating a cool flame(s) using a plasma-assisted combustion, and maintaining the cool flame(s). The cool flame(s) can have a temperature below about 1050 Kelvin, which can be about 700 Kelvin. The cool flame(s) can be further generated using a heated counterflow burning arrangement and a an ozone generating arrangement. The heated counterflow burning arrangement can include a liquid fuel vaporization arrangement. The ozone generating arrangement can include a micro plasma dielectric barrier discharge arrangement. The plasma-assisted combustion can be generated using (i) liquid n-heptane, (i) heated nitrogen, and (iii) ozone.

Process for generating cool flame and flameless fuel oxidation using non-equilibrium plasma activation

An apparatus and method for determining the average molecular weight of a complex mixture from a plurality of test samples of the complex mixture are disclosed. The method includes a) providing a chamber having two fixed conditions and one variable condition selected from three state variables of temperature, pressure and volume; b) introducing a test sample of known mass into the chamber; c) setting operating conditions of the state variables such that the test sample will be fully vaporized into a gaseous state without decomposition or chemical reaction; and d) measuring the change of the variable condition after full vaporization of the test sample is achieved. Steps b-d are repeated for several test samples having different masses. The average molecular weight of the complex mixture is determined as a linear gradient (slope) of the relationship for the change of variable condition as a function of test sample mass.
