The composition of the combustion products of a fire in an enclosure determines to a large extent toxicity, visibility and heat release. Composition, which depends on the nature of the fuel, the oxygen supply and the temperature, has been calculated by assuming homogeneity and chemical equilibrium at a uniform temperature. Elements considered in fuels are carbon, hydrogen and oxygen. The results of simultaneous numerical solutions of the equations of material conservation, heat conservation and chemical equilibria are presented graphically; and critical temperatures for soot formation are shown for four fuels. With cellulose as fuel, quantities of the individual combustion products and ratio of carbon monoxide to carbon dioxide are shown, with temperature and oxygen deficit as independent variables.
