Every customer is concerned about the service life of products he purchases. Extending the service life of thermal oil heater is helpful for reducing customer’s costs and increasing profits. Different existing thermal oil heaters on the market have different service years.
The combustion air will be heated to the flame temperature. This heating cost money. If you have some waste heat to be used for preheating the combustion air it will pay.
The thermal oil heater is a heater that uses heat medium oil as medium for heat transfer. The low-pressure and high-temperature heating can be realized by the utilization of the high-temperature characteristics of heat medium oil.If there is too much moisture in the low-temperature heat medium oil, there will be pressure fluctuations, which will cause some other problems. In addition, if the heat medium oil does not flow in the furnace owing to the stop of pump, the oil temperature will rise and exceed the limit value, which not will greatly affect the service life of the heater and cause the deterioration of the heat medium oil.
Generally, there is moisture in heat medium oil. And, the moisture will be evaporated during the heating process of the oil. If the water vapor is not discharged from the thermal oil heater, it will cause the fluctuation of heat medium oil pressure. However, the oil-gas separator can separate the water vapor from the heat medium oil and discharge it from the heater, which ensures the stable oil pressure.
If the circulating pump of a thermal oil heater stops working suddenly. Then, some measures should be taken immediately to remove the fire source. If not, the stop of circulating pump will cause coking in the oil tube, which will shorten the service life of the heater.
1. The storage tank is used to store the heat medium oil of the heating system;
2. The storage tank is used to receive the overrunning heat medium oil；
3. The storage tank is used to supplement heat medium oil for the heating system;
4. The storage tank should be placed at the lowest position of the system;
5. A firewall should be placed between the storage tank and the thermal oil heater;
6. The storage tank should be operated at a low liquid level.
The selection of a burner of the gas-fired thermal oil heater should be determined according to the boiler proper structure and fuel characteristics and in combination with the actual conditions and requirements. In addition, this kind of boiler can adopt a waste heat recovery device to improve thermal efficiency and reduce heat energy loss.
