The aim of this project was to investigate the best scenario for designing andinstalling a natural gas burner into the Peirce-Smith Converter. Initial data wasreviewed on practices of different heating processes used in other converters andrelated devices. Development of heat balance models evaluated the heat lossesduring the various heating stages, which was achieved by using a 1D analyticalanalysis. The pattern of heat flow released inside the furnace for various burnerpositions was also analysed with the CFD software package Fluent. Thisinformation allowed for the optimisation and identification of the mosteconomical and effective position for placement of the new burner.An off the shelf burner was then decided on as it complied with Australian GasStandard and was capable of handling the three different heating processes usedin the running of the converters. Insertion and retraction of the burner system isoutlined to achieve minimal downtime between roll outs as well, a maintenanceschedule has been addressed in this project as working with combined spaces andexplosive fuel can be a very dangerous combination.With the placement of a natural gas burner the new converter furnace combustionsystem will assist in the improvement of the furnace temperature control,minimise the damage caused to the refractory which will inturn maximise therefractory life, minimise environmental effects and lower fuel expenses savingthe company a considerable amount of money.
