TOMSK, Oct 18 – RIA Tomsk. Researchers of Tomsk Polytechnic University (TPU) conducted a series of experiments at University of
Nantes (France) to measure the state of complex biofuels in the process of
microexplosive dispersion and found out exactly what conditions are needed to
completely burn biofuels in turbines and engines, the university’s press
service said on Friday.
It is specified that the TPU Research School of
High-Energy Physics has been studying for many years the use of organo-coal and
emulsified fuels prepared for example from coal-processing and oil refining
waste, plant components, and municipal solid waste. Scientists are developing
new biofuels and more effective approaches to their ignition.
"The initiation of the combustion of composite
fuels – is one of the main problems in the energy sector, as the fuel contains
water ... TPU has developed several ways to intensify these processes. In
particular, scientists propose to grind fuel droplets due to the effects of
micro-explosive dispersion (spraying)", – is said in the message.
Scientists of University of Nantes also work with
biofuels. They are looking for optimal compositions, the most effective methods
and modes of ignition. At the same time, French scientists own a powerful database
of registration equipment, which allows to register the ignition process of
various fuel components during microexplosion of fuel droplets.

"They use the 2ColorLIF method, and we – Laser Induced
Phosphorescence – to determine the critical conditions for the decay of
droplets when they are heated. Our cooperation has been going on for 2.5 years.
We exchange data and have published several joint articles in international
journals. Now we have the opportunity to conduct joint experiments", – the
press service quotes the TPU professor Pavel Strizhak.
For two weeks, Tomsk scientists conducted experiments
with biofuel emulsions prepared by French colleagues. As a result, they
determined the modes under which the maximum surface area of evaporation and
burning of fuel is achieved. Thus, the conditions are established under which
it is possible to significantly increase the rate of heat release, emphasizes
