ABSTRACT

Applied combustion systems should ensure the optimal safety of operation and required qualitative parameters of a technological process. Selection of the path equipment components is determined by pressure drops resulting from local flow resistances and by the utilisation requirements of a heated device. Their flow characteristics as well as methods for calculating pressure drops in the system and local resistance numbers are presented. The combustion process was found to influence a change in the airflow characteristics, limiting the potential for achieving the nominal power of the burner with no increased overpressure of the combustion air. The determined flow characteristics and local resistance number values can be used for the algorithms of burner designs in order to obtain optimal operating parameters.

Keywords: gas burner, substrate delivery system, resistance number
