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 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 m/s 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 "Pyrolysis Gases Produced by Fast and Slow Pyrolysis of Foliage Samples from 15 Plants Common to the Southeastern US Coastal Plain" data product) with products produced using a fire as the heat source (this data product and "Pyrolysis gases determined by FTIR spectroscopy in a wind tunnel and at Ft. Jackson, SC" data product.

A flat flame burner was used in conjunction with a radiant panel to perform fast pyrolysis of foliage samples from 15 common fuels from the southeastern United States. A pyrolyzer (kerogen retort) performed slow pyrolysis of the same 15 fuels. This data set contains the molar ratio of the light gases (CO, CO2, H2, CH4) and condensable pyrolysis products (tars) identified using gas chromatographs. Three replications of each pyrolysis experiment were performed. The data were collected in order to compare the composition of gases produced by traditional methods of pyrolysis (this data product) with gas composition produced by pyrolysis caused by heating from a wildland flame (Wind tunnel and Ft. Jackson canister and FTIR data products). The use of trade or firm names is for information and does not imply endorsement by the US Department of Agriculture of any product or service.

This data set contains pyrolysis gas composition resulting from experimental fires in longleaf pine fuel beds burned in a wind tunnel and in small experimental fires at Ft. Jackson, SC. The gases were sampled and then measured by Fourier Transform Infrared (FTIR) spectroscopy. These data were collected from the same experiments contained in the "Pyrolysis gases measured by gas chromatography and mass spectrometry from fires in a wind tunnel and at Ft. Jackson, SC" data set and many of the data files and metadata in that product describe the locations, fuels, environmental conditions and fire behavior information related to this data product. The wind tunnel data spectra were captured in real time using both static (composite sample) and dynamic (time-series) modes; the Ft. Jackson data were collected in canisters and processed offline within a day of collection. A total of 29 gases were identified including small alkanes, alkenes, aldehydes, nitrogen compounds, and aromatics, most previously measured by FTIR in wildland fires. A total of 33 static (23 wind tunnel and 10 field) and 10 dynamic (wind tunnel) samples were analyzed. Wind tunnel gas concentration data estimated using external cavity quantum cascade lasers are also included. The pyrolysis gas composition in this data set, in combination with the data product "Pyrolysis gases measured by gas chromatography and mass spectrometry from fires in a wind tunnel and at Ft. Jackson, SC", were compared with the pyrolysis gas composition determined using traditional methods contained in the data product "Pyrolysis gases produced by fast and slow pyrolysis of foliage samples from 15 plants common to the southeastern US coastal plain".
