\begin{equation}\label{eq:gas-composition-get-mass-flue-gas-components-cpp} m_{i} = \sum_{j} \frac{g_{i,j} \cdot f_{j}}{MW_{j}}\end{equation}

\(m_{i}\)	Mass of flue gas constituent i \([\unit{ \pound}]\)
\(g_{i,j}\)	Generated amount of constituent i from fuel j \([\unit{ \pound}]\)
\(f_{j}\)	Weight fraction of fuel constituent j \([\unit{ \unitless}]\)
\(MW_{j}\)	Molecular weight of fuel constituent j \([\unit{ \gram\per\mole}]\)
