Combustion is the sequence of exothermic chemical reactions between fuel and an oxidant accompanied by the production of heat and conversion of the chemical species to new ones. In the article the combustion process is demonstrated by different artworks where the author believes that the artistic demonstrations of combustion gives to this phenomenon a wider view and it becomes more attractive to the viewer.
Combustion, burning or fire is the sequence of exothermic chemical reactions between fuel and an oxidant accompanied by the production of heat and conversion of the chemical species to new ones. Combustion supplies most of the energy required by human civilisation where the visible result is fire and flames usually consisting of hot gases and light. The phenomenon of fire is mentioned already in the Bible in Genesis 15:17 as follows:”When the sun had set and darkness had fallen, a smoking firepot with a blazing torch appeared and passes between the pieces.” Probably the earliest reasonably scientific attempt to explain combustion was that of Johannes Baptista van Helmont , a Flemish physician and alchemist. He observed
the relationship among a burning material, smoke and flame and said that combustion involved the escape of a “wild spirit” from the burning material. In 1667 Johann Joachim Becher , a German alchemist and physician, proposed the phlogiston theory. According to it there exist fire-like elements called “phlogiston” that is contained within combustible bodies and are released during combustion. The theory was an attempt to explain processes such as combustion and the rusting of metals, which are now understood as oxidation. It was the great French chemist Antoine Laurent Lavoisier  who rejected traditional thinking and framed a new definition of combustion that was widely accepted. Combustion, he said, is the process by which some material combines with oxygen.
In the following combustion is presented via artworks.
Figure 1 demonstrates practical application of combustion to
burners used in domestic and outdoors gas stoves. The regular
burner and its flame are shown on the top of the figure. Due to the
arrangement of the holes in the burner that are turning outside,
the flame is also turning outside. In 1990 the author developed
an efficient gas burner in which the holes are turning to the
centre of the burner and are located at some angle with respect
to the radius of the burner. In this year, the largest manufacturer
of camping equipment in Israel launched the market with a new
product, the Rotoflame Camping Cooker.
The burner and its flame are shown at the bottom of (Figure
1) where its flame is concentrated and rotating. The stove based
on it has the following characteristics:
1) Thermal efficiency is higher by 20-25% than regular
burners. 2) Boiling of water is accelerated considerably. 3) Due
to rotation of the flame, mixing with air is better, thus reducing
air pollution. The Polish surrealist artist Jaceck Yerka  painted
Figure 2 entitled “Eruption” that demonstrates combustion
inside a big hole of a mountain. The Belgium surrealist artist Rene Magritte (1898-1967) painted Figure 3 entitled “The Discovery
of Fire” and Figure 4 (right-hand-side) entitled “Portrait of
Edward James”. In order to emphasise the effect of combustion
in artwork the authors changed the colour from yellow to red in
Figure 4 (left-hand-side).
Figure 5 is a surrealistic artwork, “The Fire”, painted by
Giuseppe Arcimboldo , Mannerism Italian painter. Figure
6 entitled “Whaaam” demonstrates combustion due to firing
of the enemy by an aircraft. Roy Lichtenstein, an American
pop artist, painted it. Rudolph Ackerman an Anglo-German
bookseller, inventor and lithographer painted Figure 7 entitled
“Fire in London”. Figure 8 entitled “Funky Fire” demonstrates a
surrealistic fire giving an impression of a terrible combustion.
Figure 9 demonstrates a surrealistic “Atomic Bomb Tree”
artwork associated with fire. Figure 10 is another surrealistic
artwork of fire entitled “Sacred Fire of Pele, Goddess of Hawaii
Volcano” that is located in the Hawaiian Art Gallery by Olga
Schevchenko . In Figure 11 an interesting surrealistic folding
fire is presented where our demonstrations are terminated in
Figure 12 by the impressive artwork of Magritte entitled “The
Gradation of Fire”. In conclusion the author believes that the
artistic demonstrations of combustion gives to this phenomenon
a wider view and it becomes more attractive to the viewer.
