- Abstract
- During this report period, revision and publication was completed on a paper entitled, "Heat of Gasification for Pyrolysis of Charring Materials." The research results described in this paper have been summarized in our previous Final Report. Our major effort during the current period was devoted to work on the experiment to measure the rate of production of volatiles and heat of gasification for pure and fire retarded cellulose. During the experiment, 25 mm diameter thermally-thick test samples are subjected to an external, radiant heat flux at levels comparable to those which occur during flaming combustion. The tests are conducted in an inert atmosphere (nitrogen) to simulate the oxygen-free condition between a diffusion flame and the fuel surface. After making the initial experimental runs, it was found that extensive modification of the apparatus was needed.
