FIRE RESEARCH - A COLLECTION OF PAPERS REPRESENTING RESEARCH COMPLETED DURING THE YEAR ENDING OCTOBER 15, 1969.
Abstract
A sand-filled pan burner was used to study the heat and mass transfer phenomena during various phases of the burning episode for large turbulent fire plumes. The total heat fluxes and radiant heat fluxes to the fuel surface are given for luminous and non-luminous flames as well as fire plume mean optical depths for axially symmetric plumes and fire plumes with fire whirls. Heat transfer and burning rates are given for vertically hanging cotton cloth panels as a function of distance from an isothermal wall. The maximum burning rate, radiant heat transfer, and convection heat transfer occurred at 3, 1.5, and 0.75 inches, respectively. Combustion of pure alpha-cellulose cylinders treated with KBr are studied to obtain the effects of size, KBr concentration and a heat flux on ignition, mass loss rates, temperature profiles and mode of burning. It is suggested that the effectiveness of fire inhibitor compounds may be limited to a given burning geometry. A literature review is given for mass coefficients for large sources as they are influenced by atmospheric phenomena. (Author)
