A field investigation was initiated in the summer 1978 to quantify the influence of meteorological factors, ignition method, and fuel conditions on the behaviour of smoke plumes from open field burning. Measurements of air quality and meteorological conditions were performed…

This report outlines the development (section 2) and testing (section 3) of a simple mathematical dispersion model, — based on Gaussin plume models for air polution, — for predicting smoke concentration and visibility reduction downwind from prescribed burns in forests. The data…

We have used the high optical absorptivity of urban and source particulates to trace their ‘graphitic” component. The optical absorptivity and the particu late carbon loading show a strong correlation. Analyses of the data indicate that primary soot emissions compose a major…

Emissions from prescribed fire vary geographically. In the Northeast, for example, prescribed fires are rare. In other sections, e.g., the southern Coastal Plain, meteorological conditions, terrain, and light fuel loads minimize atmospheric concentrations of emissions. The…

Man began an intensive program to keep fire out of the woods about 70 years ago. Periodic ground fires once common in western pine forests were reduced, and a stand type that had been open, thrifty, and fairly resistant to wildfires lost those characteristics. The current status…

Flexible polyurethane foams that are char formers are capable of smoldering combustion. The smoldering process is an oxygen-limited, heterogenous oxidation process that slowly transforms the foam to a brittle, black replica of itself; for the foam examined here, the resultant…

The mass burning rates of several polymer systems, including polycarbonates, polysystrenes, polyethylenes, and wood were determined for steady-state combustion in an apparatus similar to that constructed at Factory Mutual Research. The work was undetaken to determine the…

Generalizations of the 'opacity method' of analyzing visible smoke-plume diffusion are presented. The horizontal dispersion length, sigma-y, is derived from the outline of a plume having an arbitrary vertical concentration distribution. The vertical dispersion length, sigma-z,…

A note on the features and control of the ground (soil fires that occur at intervals of 5-8 yr in the Soviet Far East. The winter ground fires occur when the snow cover is incomplete, after a warm dry autumn and when the water table is low. These fires often do not affect the…

In compartment fires a situation often develops in which a layer of oxygen-depleted gases builds up in the upper part of the enclosure. The downward reach of such a layer can be sufficient to make its lower boundary interact with the fire plume. In that case, while the…
