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 required because the application of electric field intensity with the maximum voltage of 100 kV. Another 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 methane 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 m 3 •h-1 of oxygen and 0.051 m 3 •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.
The work is dedicated to converting microwave radiation to heat. The article analyses different ways of heating residential and utility areas. Attention is paid mainly to infrared heating. Ceramic materials suitable for converting microwave radiation to heat from refractory ceramic composites are disclosed. The cooling curves of these materials after microwave heating are characterized in detail. The paper also presents a description of a microwave reactor with a fireclay brick together with the parameters of the living room heating.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
