Matters needing attention of heat transfer oil boiler

1. For oil-gas heat carrier boilers using Starr heat transfer oil as heat carrier, the system shall be equipped with expansion water tank, oil storage tank, safety elements, measuring instruments and control devices.

2. When the heat transfer oil is put into use, at the initial stage of operation, start the circulating oil pump first, run for half an hour, and then ignite to raise the temperature. When it is used for the first time, the temperature should be raised slowly, about 20℃ per hour. When the temperature rises to 180~200℃, it should be kept warm for a period of time before it can be put into normal use.

3. When in use, check carefully to prevent water, acid, alkali and low-boiling substances from leaking into the use system. The system should be equipped with a filtering device to prevent all kinds of sundries from entering and ensure the purity of oil products.

4. After half a year's use, the oil should be analyzed once. After long-term use, if poor heat transfer effect or other abnormal conditions are found, the oil should be analyzed according to the analysis results and added or replaced. Judgment standard quantity: basic 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%, and viscosity change is not more than 10%. If one of them exceeds the standard, replace it with new oil.

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

The design and installation of heating system in heat conduction oil furnace should strictly implement the design regulations of hot oil furnace formulated by relevant state departments to ensure the safe operation of the system.

Equipment risk analysis

1, general accident, minor injuries and slight economic losses.

2, a major accident, personnel light, serious injury, death, significant economic losses.

3, major, especially major accidents, workers died, especially significant economic losses.
