Question

A producer gas, used as an industrial fuel gas with the following composition by volume: $H_{2}=28%$, $CO=12%$, $CH_{4}=2%$, $CO_{2}=16%$ and $N_{2}=42%$. Find the volume of air required for the complete combustion of $1~m^{3}$ of this gas [Air contains 21% $O_{2}$ by volume].

• A. \(1.143~m^{3}\)
• B. \(3.005~m^{3}\)
• C. \(2.286~m^{3}\)
• D. \(1.523~m^{3}\)

Hint:

Always ignore \(CO_{2}\) and \(N_{2}\) in combustion calculations as they are already fully oxidized or inert. Focus only on the "hungry" molecules like \(H_{2}\), \(CO\), and Hydrocarbons!

Answer 1

The Correct Option is A
