A first assessment of the finding of Professor of National Technical University of Athens, Dimitris Karonis, for the Tempiperformed by talking to newsit.gr Kostas Kappos is a mechanical-engineer and energy engineer, specializing in burns and flares.
As he reports on The Technical University’s finding for Tempiit was obvious that “there was no possibility that there was another flammable material, when the sequence of the events betrayed, at least to people who knew some things about them, how the fire was ended.”
Mr. Kappos explained what happened, among other things: “The passenger train transformer, because this is why the bickering is done, suffered scary mechanical stress, shells, deformations that led to a short -circuit of the middle voltage of 25,000 V. They turn into flammable gases and these flammable gases are ignited. “
“The distinguished colleague examined all the details without any prejudice”
“A first reading of the Karoni exhibition, because of course consists of 123 pages and it is not easy for any technician to examine it within 1 hour and conclude, need more examination, but I see that the distinguished colleague examined all the elements without any prejudice and the only one, They see, while “dancing in front of their eyes” to say so popular. That is, it was obvious, something obvious that there was no possibility that there was any other flammable material, when the sequence of the events betrayed, at least to the people who knew some things about them, how the fire was ended, “Mr. Kappos said.
And he goes on to say: “There has been a sequence of events, which excludes the existence of elaborate materials that have long been saying, that is, I can tell you in a list of events exactly what happened that night, those seconds that ended up in the tragic event. In the first phase, what we saw was a trading train weighing about 800 tonnes and a speed of 100 km/h colluting with a trading train weighing about 550 tonnes and had a speed of about 150 – 160 km/h. With a minimum time available for braking, braking, which did not reduce their speeds more than 10%. This kinetic energy released within 2, 3 seconds is equivalent to putting 210 kg explosive TNT and suffering the consequences of such an explosion. That is, the electrician of the passenger train and the canteen wagon was literally dissolved, killing most of the victims instantly. At the same time, however, the transformer of the passenger train, because this is why all the fight is done, suffered frightening mechanical stresses, shells, distortions that led to a short -circuit of the 25,000 V voltage and the creation of an electric arc, flammable gases to ignite. This essentially created all this fireplace and we are talking that this process is done within two milliseconds. That is, from the time of the collision within two milliseconds, if there is an electric arc, due to a short circuit, this whole process is automatic, huge amounts of elafal gases are produced, that is, hydrogen, methane, ethani, methylene, methylene.
“If 1 liter of oil is ignited by the transformer, 8000 liters of bilar gases are produced”
“This is exactly what Mr. Karonis was examined, of course in a much more detailed way. Quitable all the quantities of these elaborate gases produced by the burglary and short circuit of the transformer and gave us this fireplace. Imagine that if 1 liter of oil is ignited by the transformer, 8000 ransom of diligence gases are produced. That is, for 1000 liters we can say that they took part in this ignition, 8,000 cubic meters of cross -gases were created that created this fireplace. So this thing was examined by Mr. Karonis, and on the other hand, these traces of wood, which were found around the train, were nothing more than some pollutants. We call pollutants, that is, when an organic matter is burned and this burning is incomplete, it is not perfect with blue flames because there is oxygen overtraining, a whole bunch of aromatic compounds are created as pollutants, who fall around and have found some of them! This was some material carried by the train, ”he says.
And he concludes: “What needs to be added to this issue, but I think they are more responsible for the lawyers to explain than a technician as me, is that by excluding the quantity and smuggling of flammable materials on the train, we need to think about what extensions are in the way.
