double wall ceramic mugs How the structure and working principle of the electric heater?

double wall ceramic mugs cupOut of order from the working oil tank, heavy oil is further heated to 110 ℃, the viscosity of the heavy oil is further reduced, thereby enhancing the atomization of the burners, domestic ceramics factory generally set between the supply pump and the oil burner heavy oil electrically heateddevices.

Electric heater structure is very simple, the main heating element in a steel casing loaded. The heating element is a nickel chrome resistance wire on a small metal pipe, the rest of the capillary tubes of the voids filled with oxides of good thermal conductivity and insulating performance. Pass on the current, its maximum operating temperature of 300 ° C, Serve a heating element. Use, the heavy oil from the inlet pipe into the inside, the contact with the heating element is heated to about 110 ℃, i.e. from the outlet, into the pipe, the output to an oil burner, for its atomization and combustion. Effective heating surface of the heater, must ensure that the dip in the heavy oil. For safety
reasons, usually installed point of contact thermometer, and temperature of the automatic adjustment, so that the heavy oil to the heating does not exceed a predetermined maximum temperature.
