This study presents the description of a computer program developed for purpose of carrying out an approximate heat balance for a rectangular furnace at the design stage. This is often necessary in order to determine the heat input, its expenditure and the fuel consumption. The program which was written in MATLAB estimates surface areas, calorimetric and actual furnace temperatures, input heat from fuel combustion and the heat output for metal melting, waste gases, and lining losses. Fuel requirement was obtained by equating total heat input and output. The various percentages were determined as well as the thermal indicators. The result of the application of the program to a furnace design of dimension 700600600 mm using gaseous fuel (Butane) is presented. The percentage of heat lost through the waste gases, the unit energy consumption and coefficient of total heat utilization compare well with what is obtainable in practice as revealed in literatures. The program will be useful for furnace design purposes.
