This paper discusses the generation and use of a data package for the validation of a computer model of a horizontally fired, cylindrical, research tunnel furnace. The combustion experiments discussed in this paper involved the combustion of either coal or oil in eleven separate experiments. The volatile content of the coal varied from 21 to 35 percent by weight and the swirl number of the flow varied from 0.0 to 0.4. The measurement scheme included the axial variation of the total and radiant heat flux from the flame, and a mapping of the gas temperature and major species concentration profiles. To complete the measurements inside the furnace a mapping of the gas velocity profiles was made at two total air flow rates and seven swirl settings ranging from a swirl number of 0.0 to 0.9. The use of these data to validate a combustion simulation code is demonstrated in this paper. The computer code used for this study is called 'MODTUN' and was developed at Imperial College. This computer program is based on the 'TEACH' code and incorporates the necessary sub routines to model the devolatilization and combustion of pulverized coal. A reasonable measure of success was obtained in comparing the measured to predicted data. By using this data package not only was it possible to determine the appropriate models for the physical processes involved but empirical parameters for these models were also identified. The most significant of these is the amount of volatile material released relative to that predicted by proximate analysis.
