【 摘 要 】

In this paper was solved modification of combustion burner for experimental exam of methane combustion in the electric field with high intensity voltage. The burner was originally designed for the combustion stack gas. The burner must have been necessary adjusted, because the mixture of stack gas and air was replaced by mixture of methane and oxygen. The fundamental requirement is to adjust the height of the flame that may reach a maximum of height 100 mm. This height was re-quired because the application of electric field intensity with the maximum voltage of 100 kV. An-other objective was to achieve a geometrically stable methane-oxygen flame. Gas mixture of methane and oxygen were chosen because the simplicity of combustion reactions. This paper includes a detailed description of stack gas burner, the recalculation of the parameters for a mixture of me-thane and oxygen with the calculation of flow rate regulation for individual gasses, calculation of flow velocity and differential pressure. From the results of calculations and using the experimental configuration, the burner was configured on flow rate 0.1045 m3·h-1 of oxygen and 0.051 m3·h-1 of methane and pressures 2 bar for methane and 5.9 bar for oxygen, which corresponds to approximately power of burner 0.5 kW. At this setting, the flame showed a perfect geometry and flame height for the subsequent application of high intensity electric field to the flame zone.
