| Abstract: | Based on electrothermal principle and heat transfer theory,calculation formulas of electro heat parameters for direct resistance heating appliance are deduced in this paper.Working voltage can be confirmed by the parameters of the end of the heating.Heating up time can be calculated by cut and try method.The measures of increasing power factor,electrothermal efficiency and decreasing specific electricity consumption are proposed.These form an important basis for industry. |
