Following the oxygen consumption principle and specification method, a calculation method of combustion and species concentrations in a zone fire model is presented. Firstly, combined with McCaffreys empirical formulas for plume entrainment, the calculation method of heat release rate of the fire source is discussed; secondly, based on the mass balance of the individual atoms in chemical reactions, species producing rates in the combustion process are calculated with specification method; then, the formulation for calculating species concentrations in each zone is given from the mass conservation principle. On the above basis, a numerical example is given to predict the heat release rate and species concentrations. Also, the numerical and experimental results of the interface height, average temperature rise of each room and the pressure difference between the two rooms near the ceiling are presented. Finally, the advantages of the method and the work necessary to be further studied are analyzed.
