Abstract
Thermal generation of combustible vapors has been measured up to 500°C for green Douglas-fir, ponderosa pine, and lodgepole pine foliage. The relative contributions to combustible products are given for ether, benzene-ethanol, and total extractives, as well as for holocellulose and lignin. Each of these components makes a sizeable contribution to flammable vapors. Extractives account for about 80 percent of the volatiles below 300°C. Most of these low-temperature volatiles were extracted with benzene-ethanol, but only 15 to 30 percent were ether soluble. For thè fuels, ether extractive content was found to be of limited value as an indicator of diffénces in flammability. Forest Sci. 26:347–360.
