Open Condition 11005SecondPort 4; 40 kW loading experiment; The model assumes initial adiabatic flame temperature (2071 °C) and a linear temperature decay to Port 1. PFAS introduced with the natural gas or combustion air (t=0 sec) experience the full temperature profile (Figure 3) and flame chemistry before being analyzed by FTIR at Port 18 (t~7.4 sec). However, PFAS introduced at Ports 4‐12 experienced reduced temperatures, residence times, and exposure to flame chemistry.
