Intermediate Heat Transfer Medium for Thermal Oil Heaters

A thermal oil boiler is a boiler that utilizes thermal oil for heating. Thermal oil, also known as organic heat carrier or heat medium oil, has been used as an intermediate heat transfer medium in industrial heat exchange processes for over 50 years. This type of direct-flow boiler is developed based on a forced circulation design. It typically uses coal, oil, or steam as fuel, with thermal oil as the medium. A hot oil circulation pump forces the medium through liquid phase circulation, delivering heat energy to heat-consuming equipment before returning it to the heater for reheating. This system achieves high operating temperatures at low pressures and offers high control over the medium's operation. Today, we've summarized the performance and features of thermal oil heaters, hoping they will be helpful. As a high-quality heat source, this electric thermal oil heater can deliver hot oil up to 350°C at atmospheric pressure. The main heating power supply utilizes a solid-state module contactless switching circuit, accommodating frequent on/off cycles without disrupting the power supply network. It also features dry-burn protection. A hot oil cooling system can be added upon request to meet production process requirements requiring rapid cooling after a temperature rise. Energy conservation and low operating costs. High thermal efficiency and economical performance. Heat utilization is 40%-50% higher than steam. The thermal oil boiler system operates in a closed liquid-phase circuit, with a 20-30°C difference between the oil outlet and return temperatures. This means that heating only requires a 20-30°C difference to reach the operating temperature. Furthermore, this system requires no water treatment equipment and eliminates the heat losses associated with steam boilers, such as evaporation, dripping, or leakage. This results in high heat utilization, saving approximately 50% energy compared to steam boilers. Low equipment investment. Due to the simplicity of the thermal oil boiler system, the lack of water treatment equipment and extensive auxiliary equipment, and the low boiler pressure, the overall system investment is relatively low.
