Abstract:

Pyrolytic and flaming combustion gases were sampled in a series of experimental fires in a small wind tunnel at the U.S. Forest Service laboratory in Riverside, CA and in 30 meter (m) x 30 m plots in longleaf and slash pine forests located at Ft. Jackson, SC. Wind tunnel fires burned 2.4 m long fuel beds composed of longleaf pine needles and combinations of small fetterbush, sparkleberry, blueberry and inkberry nursery-produced plants under no wind and 1 meter/second wind. Gases were captured in canisters and consist of light hydrocarbons up to C7, CO, CO2, H2 and light aromatics. 88 wind tunnel fires and 5 field fires yielded a total of 195 canisters. The objective of the experiment was to compare pyrolysis products produced by traditional methods (see the data product "Pyrolysis Gases Produced by Fast and Slow Pyrolysis of Foliage Samples from 15 Plants Common to the Southeastern US Coastal Plain" - https://doi.org/10.60594/W4WC78) with products produced using a fire as the heat source (this data product and the data product "Pyrolysis gases determined by FTIR spectroscopy in a wind tunnel and at Ft. Jackson, SC" - https://doi.org/10.60594/W41596).
