Heat transfer oil boiler

It is strictly forbidden to mix water or other low-boiling impurities and flammable and explosive substances into the heat-conducting oil. When driving, the water in the system should be drained first, then the intake valve and the check valve should be opened, and the temperature should be raised to remove the water in the heat carrier; the newly replaced or added heat transfer oil must be preheated and dehydrated before it can be added; In case of moisture, the air valve should be opened first, and then the temperature of the heat transfer oil should be raised to 150℃ with a heating rate of 5℃/h on a small fire, so that the moisture can evaporate and escape. Then close the vent valve, and heat it up to 250°C at a heating rate of 10°C/h. During the heating process, if you hear the sound of water hammer or see that the pressure is too high, you should immediately open the large vent valve to expel the water vapor, and then close the vent valve to drive. When the furnace is shut down, t
