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 the report.
