- Abstract
- In this paper the problem of cellulosic material burning in air is explored in the following three ways: (1) The buoyant boundary adjacent to a fuel surface is examined to obtain heat tne mass transfer coefficients for fuel elements of a variety of sizes and orientations. (2) The gross behavior of burning cellulose cylinders, pressed from pure a-cellulose filter clippings is studied. (3) Cellulose cylinders were pressed, cured and dried. Thermocouples were installed on the surface and at varying depths. Tests were run at temperatures which precluded pyrolysis but permitted the determination of the thermal diffusivity and the uniformity of the material.
