Thermal oil furnaces are widely used as heating equipment in many places. But how much do you know about the detailed usage of thermal oil furnaces? Below, the editor introduces a few points for you:

The required temperature of the material being heated in the thermal equipment of a thermal oil heater determines the operating temperature of the thermal oil. The temperature of the thermal oil must be higher than that of the heated material. The greater the temperature difference, the smaller the heating area required. A larger temperature difference necessarily leads to a higher thermal oil temperature. However, certain chemical materials are prone to cracking and carbonization at high temperatures. Therefore, the selection of the temperature difference should be determined based on specific circumstances to avoid the thermal oil exceeding its maximum operating temperature or damaging the heated material.

Thermal oil heaters are crucial equipment in heating systems. To prevent overheating and coking, the flow rate of thermal oil within the furnace tubes should not be too low. However, a high flow rate increases fluid resistance, leading to higher energy consumption from the circulating pump. The exhaust gas temperature of thermal oil heaters is relatively high, typically ranging from 300 to 400°C. Auxiliary heating surfaces such as air preheaters or energy-saving water heaters should be added at the tail end to reduce exhaust gas temperature, thereby improving thermal efficiency and conserving energy consumption.
