. Heating of chemical materials in the chemical industry, some powder drying under certain pressure, chemical process of air heater manufacturers and spray drying.
2, hydrocarbon heating, including petroleum crude oil, heavy oil, fuel oil, heat transfer oil, oil, paraffin and so on.
3. Process water, superheated steam, molten salt, nitrogen (air) gas, water gas, etc., which are heated by heating.
Commissioning Procedure for Air Heated Tubes The air heater housing and control cabinet enclosure are reliably grounded. Whether the power cable, output wiring, and thermal resistance wiring are correct, the insulation is good, and the components and fasteners of the control cabinet are loose. If there is any abnormality, it should be dealt with in time. Close the power switch, close the air switch in the control cabinet, the relevant indicator light should be on, and the digital display temperature controller light is on. Set the highest and lowest temperature values on the intelligent digital display temperature controller. The electric heater is turned on, the heater starts to work, and it is automatically controlled according to the set temperature. When the temperature is lower than the minimum value, the electric heater is automatically activated; when the temperature exceeds the highest value, the control cabinet alarms the power failure, the electric heater does not work, but can maintain a certain temperature for a short time. Move the transfer switch to check if the three-phase voltage is balanced. If there is an imbalance, you can change the phase and balance. If it is still unbalanced, further inspection and treatment are required.
