What should I do if the temperature of the expansion tank of the organic heat carrier boiler is high

Guide: The organic heat carrier boiler can reach a higher temperature with a lower working pressure, and can be used in the drying process of a variety of industries. The boiler is equipped with an expansion tank and an oil storage tank, which together with the pipeline constitute the heat transfer oil circulation system of the boiler. What should I do if the temperature of the boiler expansion tank is high? The organic heat carrier boiler is also called the heat-conducting oil boiler. What are the functions of the high-position tank of the heat-conducting oil boiler?

1. Solutions to the high temperature of the expansion tank of the organic heat carrier boiler

　　1- Is the installation height of the expansion tank insufficient? Normally, the bottom of the expansion tank needs to be 4-6 meters higher than any oil passing point;

　　2-Is the auxiliary exhaust valve not closed? That is, the valve on the auxiliary exhaust pipe connected to the oil return line and the top of the expansion tank should be closed during normal operation; the heat carrier boiler has good energy-saving effect, and the tail is equipped with a waste heat boiler or an economizer. Effective use of boiler waste heat.

　　3-Is the initial boiling point of the heat-conducting oil low? This should contact the heat-conducting oil supplier to issue a test report, and then find the heat-conducting oil boiler supplier to confirm whether the initial boiling point is too low? That is the oil problem;

　　4- The pressure of the system should also be considered to prevent the pressure of the return pipe from being higher than the static pressure of the expansion tank, resulting in circulation;

2. The function of the high slot of the heat-conducting oil boiler

　　1. The heat transfer oil expands in volume as the temperature rises during the heating process. The expansion tank is used to accommodate the excess heat transfer oil due to expansion. The heat transfer oil expands, buffers and stores in the tank, so it is called the expansion tank .

　　2. When the amount of oil in the system is insufficient due to the leakage of heat transfer oil and the evaporation of low boiling substances generated during operation, an appropriate amount of oil can be supplemented to the system to act as an oil supplement tank.

　　3. The expansion tank can play the role of the exhaust tank for the gas discharge generated during the dehydration, boiling process and high temperature operation of the system.

　　4. For systems using nitrogen sealing, it plays the role of nitrogen sealing tank. The position of the boiler oil tank in the system is important to the crew, and the user should choose carefully.

　　5. The expansion tank is placed in the highest position of the heating system to supplement the pressure head and has the function of a high-position tank. Make the suction port of the circulating pump have a considerable liquid column pressure to ensure that the pump does not produce cavitation and maintains normal operation.

　　6. In the event of a sudden power failure, the cold oil in the expansion tank can be used to replace the hot oil in the heating furnace to act as a replacement tank. The cold oil in the expansion tank is used to absorb the heat storage in the furnace and reduce the furnace temperature, which can protect the heating furnace and ensure that the oil film does not over-temperature.

　　7. Oil can also be injected into the expansion tank when the system is filled with oil, and it flows from the expansion tank to the heating furnace and the system, acting as an intermediate tank.

The above introduces the high temperature of the expansion tank of the organic heat carrier boiler to solve the function of bibimbap and the high tank of the boiler.
