Abstract:

A new methodology was developed to conduct combustion experiments under constant global equivalence ratio (GER) conditions using a modified Fire Propagation Apparatus (FPA). The approach maintains fixed ventilation by applying calibrated, time-dependent air-flow profiles, enabling GER to remain constant despite continuous changes in fuel-pyrolysis rate. This method overcomes a key limitation of conventional FPA testing, in which time-varying GER introduces uncertainty in relating species yields and heat release to ventilation conditions. Continuous measurements of O2, CO2, CO, total hydrocarbons, particulate matter, NO, and HCN were obtained using calibrated analyzers, and the characteristic residence time of the combusting mixture in the test section was incorporated into the analysis framework.
