Thermal Oil Boiler Precautions

Precautions

1. For oil and gas heat carrier boilers that use thermal oil as the heat carrier, the system should be equipped with expansion tanks, oil storage tanks, safety components, measuring instruments and control devices.

2. When the heat transfer oil is put into use, at the beginning of operation, start the circulating oil pump first, and then ignite and heat up after half an hour of operation. The temperature should be raised slowly during the first use, and the temperature should be about 20 ℃ per hour. When the temperature reaches 180~200 ℃, keep it warm for a period of time before it can be put into normal use.

3. During use, check carefully to prevent leakage of water, acid, alkali and low boiling point substances into the use system. The system should be equipped with a filter device to prevent all kinds of debris from entering and ensure the purity of the oil.

4. After half a year of use, an oil product analysis should be performed. After long-term use, if the heat transfer effect is poor or other abnormal conditions are found, the oil product should be analyzed, and the addition or replacement should be decided according to the analysis result. Judgment standard amount: alkali carbon is not more than 1.0%, acid value is not more than 0.5mgK(OH)/g, ignition point change is not less than 20%, viscosity change is not more than 10%, one of which exceeds the standard should be replaced with new oil.

5. In order to ensure the normal service life and heat conduction effect of heat transfer oil, it is strictly prohibited to use it over temperature.

6 The design and installation of the heating system of the heat-conducting oil furnace should strictly follow the design regulations of the hot oil furnace formulated by the relevant state departments to ensure the safe operation of the system.
