Pyrolysis Gases Measured by Gas Chromatography and Mass Spectrometry from Fires in a Wind Tunnel and at Ft. Jackson, SC

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.

本数据集的气体样品采自两类实验场景：一是位于美国加利福尼亚州里弗赛德市的美国林务局（U.S. Forest Service）实验室小型风洞系列燃烧实验，二是南卡罗来纳州杰克逊堡的长叶松（longleaf pine）与湿地松（slash pine）林地内的30 m × 30 m野外火烧样地。风洞燃烧实验的燃料床总长2.4 m，燃料由长叶松针叶，以及苗圃培育的小型绊脚木（fetterbush）、亮果越橘（sparkleberry）、蓝莓（blueberry）和墨叶冬青（inkberry）的混合植株构成；实验分别在无风与1 m/s风速条件下开展。采集的热解与有焰燃烧气体被储存在采样罐中，成分涵盖碳数不超过C7的轻烃、一氧化碳（CO）、二氧化碳（CO₂）、氢气（H₂）以及轻芳烃类物质。本次实验共完成88次风洞燃烧与5次野外火烧，累计获得195个采样罐样品。本实验的核心目标为对比传统热解方法生成的热解产物（参见数据集《美国东南沿海平原常见15种植物叶片样品的快速与慢速热解气体》）与以火烧作为热源生成的热解产物，即本数据集以及《风洞与杰克逊堡现场通过傅里叶变换红外光谱（Fourier Transform Infrared Spectroscopy, FTIR）测定的热解气体》数据集所收录的产物。
