the development of culture fire began to render more and more benefits to the Man. In the Middle Age people have already abandoned the worship of Fire as divinity; the scientists began to study the phenomenon of fire and came to the conclusion that the combustion of a substance is the escape from this substance of a subtle and imponderable element,
which they termed as 'Phlogiston'. 85. 2784, p. 68–
"After about 300 years, with the development of expeirmental chemistry, the scientists, amongst them, the famous A.L. Lavoisier (1743-94), came to the conclusion that combustion means combination of a substance with the oxygen, with resulting evolution of heat. Finally, about 50 years ago, experiments showed that in the absolute absence of water-vapours, combustion of a substance does not occur or occurs with great difficulty. This means that combustion is fostered considerably by the presence of steam or moisture. With further research on combustion still due, it may be said that in the process of flame-less combustion, or perfect combination of gas and oxygen on the incandescent refractory surface, the surface shows negative charge, which leaves room to believe that combustion or combination of a substance with the oxygen means ionisation of the
reacting substances." 86. 284, Page 28–
"Fuel is a substance which, when burnt, i.e., on coming in contact and reacting with oxygen or air, produces heat. Thus, the substances classified as fuel must necessarily contain one or several of the
following combustible elements : carbon, hydrogen and hydro-carbons." 87. 248-t, page 28– - "Fuels may be classified in various ways, i.e., (1) according to the
physical state in which they exist in nature-solid, liquid and gas
eous..." 88. 2018-7, page 128
"Chemical reactions among substances take place more quickly and intensively, the closer is the contact among the reacting substances and the larger the surface of contact. The duration of a chemical reaction depends upon thermal conditions, which might be created either before the beginning of reaction, or during the reaction. All chemical reactions, in the present case combustion, i.e., combination
