<p class="MsoNormal"><span style="font-size:13.5pt;font-family:times;color:#00002E;background:white">Was this written by someone who is unfamiliar with combustion? How could such a statement be supported? Liquid hydrocarbons are easily burned soot-free by
providing the correct conditions. Kerosene is an example of a hydrocarbon fuel. Not only is it possible to burn it without any formation of soot, it can be burned without any flame! The Japanese have led the field for some time (FLOX, it is called – flameless
oxidation). <o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:13.5pt;font-family:times;color:#00002E;background:white">So the formation of a swirling blue flame brings these researchers from the past into the 80`s or 90`s. FLOX moves past having any flame at all. Perhaps that
will provide the next opportunity for a coding project.<o:p></o:p></span></p>
