Evaluating the Global Equivalence Ratio Concept for Compartment Fires: Part II–Limitations for Correlating Species Yields:

An examination of the suitability of the Global Equivalence Ratio (GER) to a compartment with prototypical building features for the prediction of carbon monoxide generation is presented. Based on an analysis of the species yields, it is seen that the GER concept is not appropriate for correlating and predicting species generation in prototypical building fires. In addition, the analysis showed that the species yields need to be calculated accounting for external burning. A new methodology to correlate the species yields from a compartment fire is presented and discussed. Good correlation for all four species examined in this study was obtained based on the new methodology.
