calculate the theoretical oxygen to fuel ratio for acetylene?? Answer is 3.1
Homework Answers
Acetylene : C2H2
Balanced Oxidation reaction of acetylene : C2H2 + 2.5 O2 ------> 2CO2 + H2O
Atomic weights of the atoms that make up Acetylene and oxygen:
- Carbon (C) = 12.01
- Oxygen (O) = 16
- Hydrogen (H) = 1.008
*So 1 molecule of Acetylene has a molecular weight of: 2* 12.01 + 2 * 1.008 = 26.036 amu
*One oxygen molecule weighs: 2 * 16 = 32 amu
*The oxygen-fuel mass ratio is then: 2.5 * 32 / 1 * 26.036 = 80 / 26.036= 3.07
*So we need 3.07 kg of oxygen for every 1 kg of fuel.
*Rounded to single decimal place : we need 3.1 kg of oxygen for every 1 kg of acetylene.

Gas fired furnace (a) Oxygen-gas combustion is being pursued for use as a supplement and/or replacement for conventional air-gas chemistry in a variety of applications. The first order design assessment in such instances is illustrated in part by the following thermochemical analysis of an acetylene cutting torch burning oxygen or air. Using ideal complete combustion of acetylene at equivalence ratio values of 1.00, 0.83, 0.71, determine (i) the mass of oxidant consumed per mass of fuel burned for oxygen and...
