Theories of Combustion

Lavoisier checked Ptiesdey s work and recognizing that air contains mainly two gases, named one vital air and the other azote (nitrogen), the latter not supporting life. Later, vital air became oxygen, from the abiUty to form acids ox, ie, sharp (taste) 2in.dgen, to form. In 1777, Lavoisier developed the theory of combustion. His ideas became widely estabhshed and were firmly fixed by his textbook, Ixi Traitu Elumentaire de Chemie (2). 

Draw the fire triangle and explain the simple theory of combustion. 

The aim of this section is to introduce the fundamentals of incineration, adsorption, absorption, condensation, and biological treatment in order to provide a basic knowledge for the selection of suitable equipment. The waste gas characteristics that play a major role in the selection of gas-cleaning equipment are also considered. A detailed presentation of the theory of combustion, adsorption, absorption, condensation, or biological decomposition required for a complete understanding of the subject is not covered in this section (the theory can be found in the handbooks such as Perry s Chemical Engineers Handbook). 

A. L. Lavoisier recognized oxygen as an element, developed the modem theory of combustion, and demolished the phlogiston theory.

After Lavoisier had developed his theory of combustion, he was able to go a step further. First, with the assistance of the physicist Simon Laplace, he repeated Cavendish s experiment by burning hydrogen and oxygen in a closed vessel. Next, he passed steam over red-hot iron and found that it could be decomposed into hydrogen and oxygen again. Clearly, water was not an element. It was a compound formed from two gaseous elements. 

The scientific revolution that began when Lavoisier announced his new theory of combustion was far from over. Chemists stuck to the phlogiston theory and some of them continued to cling to the old four-element theory as well, objecting that Lavoisier hadn t really shown that water could be decomposed. The hydrogen, they said, could have come from the hot iron over which the steam had been passed. 

Georg Ernst Stahl, 1660-1734. German chemist, physician, and professor. Co-founder of the phlogiston theory of combustion. Author of Fundaments Chymiae Dogmabcae et Expenmen-talis. He distinguished between potash and soda and recognized that alum contains a peculiar earth different from all others. 

John Mayow, 1641-1679, English chemist and physician, who died quite young. Famous for his early researches on combustion and respiration His theory of combustion was described in his tract entitled "De Sale Nitro et Spirito Nitro-aereo in 1674 ( 48).
