As illustrated in Fig. 13, above, the heptane spray burner represented the worst-case ignition source of those investigated, because it was not extinguished by the 50% propylene glycol solution. Additionally, the heptane spray burner produced a steady baseline fire size that increased the overall reproducibility and reliability of the ignition source. Tests were conducted by lighting the heptane burners, adjusting the heptane flow rate, allowing for 2 minutes of heating, and flowing antifreeze solution to an open A Scope A – Spray Ignition 25 sprinkler.
Further development is needed to characterize the droplet size distributions produced by a variety of sprinklers. The development or investigation of a small or medium scale test for ignition of antifreeze sprays may contribute to understanding the droplet size distributions of antifreeze that have the potential to ignite. Finally, the results of this research indicate that certain concentrations of glycerin and propylene glycol antifreeze solutions are not appropriate for use in residential sprinkler systems.
