Difficult problems of boiler heat transfer oil

1.Theoretically, the highest point of the boiler should be the highest point of the boiler body, and the exhaust pipe seat is set at the highest point of the boiler, and the separator is installed above the exhaust pipe base;

2.The temperature of the upper oil tank should be basically the same as the ambient temperature, and the small amount of gas separated has no great effect on the temperature of the oil tank.

What model of boiler do you have?

Boiler fuel is broadly divided into coal, oil, gas, and its combustion inevitably consumes resources and emits carbon dioxide, among others. But it is only one of the items in energy conservation and emission reduction. There are also electricity saving, water saving, etc. Therefore, boiler fuel is inseparable from energy conservation and emission reduction, and is included in it.

For example: Beijing Weilang Century Technology ****.

Dynamic thermal control energy-saving system.

Imported equipment for energy saving and emission reduction of gas-fired oil hot water boilers. By dynamically adjusting the combustion mode of the boiler, the combustion time of the boiler is reduced, and the water output of the boiler is guaranteed to meet the requirements of use. Reducing the combustion time also reduces the amount of gas, and the reduction of gas volume also reduces the emission of carbon dioxide and other gases.

Standard energy saving and emission reduction. But it's just gas oil.

It is obviously caused by carbon deposits in the heating coil, and it is recommended to use carbon deposition cleaning agent to remove the carbon deposits. At the same time, the heat transfer fluid you used is reported to be discontinued after testing. The reason why you want to stop using the heat transfer oil is that the heat transfer oil you are using now has been used for a long time, and it is easy to form carbon deposits in the coil.

Therefore, it is recommended that you switch to a new heat transfer fluid after removing the carbon deposits.

Analysis: The boiler heated by heat transfer oil is called heat transfer oil boiler. Heat transfer oil, also known as organic heat carrier or hot medium oil, has been used as an intermediate heat transfer medium in the process of industrial heat exchange for more than 50 years.

Compared with the traditional heat transfer medium water and water vapor, heat transfer oil has the following characteristics:

At almost atmospheric pressure, very high operating temperatures can be obtained. That is, it can greatly reduce the operating pressure and safety requirements of the high-temperature heating system, and improve the reliability of the system and equipment.

It can meet the process requirements of heating and cooling at different temperatures in a wider temperature range, or realize the process requirements of high-temperature heating and low-temperature cooling with the same heat transfer oil in the same system. i.e., it can reduce the complexity of systems and operations;

The water treatment system and equipment are omitted, which improves the thermal efficiency of the system and reduces the maintenance workload of equipment and pipelines. That is, it can reduce the initial investment and operating costs of the heating system;

In the case of a leak in the system caused by an accident, there is a possibility of combustion when the heat transfer fluid meets an open flame, which is a problem for the heat transfer oil system compared to the water vapor system. However, in the absence of leakage, the heat transfer oil system is safer to operate than the water and steam system because it operates at low pressure.

Compared with molten salt, another type of high-temperature heat transfer medium, when the operating temperature is more than 400, molten salt has an absolute advantage over heat transfer oil in terms of heat transfer medium and service life, but it is at an obvious disadvantage in other aspects, especially in the complexity of system operation.

Summary. There are several possibilities for this situation you mentioned, first, first check whether the branch valves are not closed or other valves that should be closed or opened are not properly switched, resulting in the heat transfer oil not reaching the equipment and returning directly to the oil furnace system.

There are several possibilities for the situation you said, first, first check whether the branch valves have straight valves and have not been closed or other valves that should be closed or opened are not properly switched, resulting in the heat transfer oil not rolling and not reaching the equipment and returning directly to the oil furnace dry residual system.

Second, check whether the pressure gauge of the boiler in and out of the main pipeline has pressure or pressure difference, if there is no pressure or the pressure is too low, it means that there may be a problem with the main circulation pump of heat conduction oil, or the system lacks heat transfer oil, check whether the filter screen in front of the pump is blocked, check the oil level of the high groove, and quietly burn to see if there is a lack of oil.

Third, check whether there is a pressure difference between the inlet and outlet pressure gauges of the thermal equipment, and if the pressure difference is large, it means that the thermal equipment is blocked. You can check the heat conduction oil system according to these points, and if you have any questions, you can call our company for ** consultation.
