Abstract: Optimisation studies based on computer simulations of a 450kW combustion chamber are presented and discussed. A matrix burner which develops an array of premixed flames is used in this type of combustion chamber to achieve power modulation. The optimisation parameters were pollutant emissions, efficiency and simplicity of construction. In addition to the currently used combustion chamber, four other geometrical configurations or modifications were considered and simulated. Two of them were found to be better than the current combustion chamber geometry: (1) The insertion of a heat exchanger in the combustion chamber would reduce NO_x emissions; (2) using a flat bottom configuration of the combustion chamber instead of a round bottom one would be a simpler configuration and would not change the other optimisation parameters.
