Sažetak
A gas burner is a device which delivers defined amounts of gas fuel and oxidiser to the combustion zone as well as stabilises the flame at its outlet and ensures it has required parameters, i.e. a proper shape and, determined by the heating process, an appropriate level and a balanced distribution of temperatures. Selecting a burner for an existing furnace and designing a new burner for a furnace under development are very complex tasks. Intensification of flame gas dynamics requires high pressure to ensure a high outflow substrate velocity. In the paper, aspects of optimal utilisation of diffusion gas burners are presented. The effects of design and gas-dynamic parameters on burner operation in terms of applied optimisation criteria were analysed. The combustion process was found to influence a change in the air flow characteristics, limiting the potential for achieving the nominal power of the burner with no increased overpressure of the combustion air.
