The core working principle of a thermal oil boiler is: the thermal oil is heated to a certain temperature (usually 30ºC-350ºC, and special models can reach higher) through a heat source (fuel combustion or electric heating), and then the circulating pump drives the thermal oil to circulate in a closed system to transfer heat to the heat-using equipment (such as reactors, dryers, etc.). The cooled thermal oil returns to the boiler for reheating to form a closed-loop heat transfer cycle.
Thermal oil (also known as heat transfer oil) has the characteristics of good thermal stability, large specific heat capacity, and high boiling point (up to 300ºC or more at normal pressure). Therefore, it does not need to rely on a high-pressure environment like a steam boiler to provide a high-temperature heat source. The system is safer to operate and has less heat loss.
1. High efficiency and energy saving
The heat transfer efficiency of thermal oil is high, and the heat utilization rate can reach more than 90%, which is much higher than that of traditional steam boilers (about 60%-70%);
There is no loss of steam condensate, and there is no need to consume a lot of water resources (only a small amount of thermal oil needs to be replenished), and the operating cost is lower.
2. Stable temperature and precise temperature control
The thermal oil can reach high temperature (such as 300ºC) at normal pressure or low pressure, and the temperature fluctuation is small;
With intelligent control system, it can achieve precise temperature control of ±1ºC, meeting the precision process requirements of chemical, food and other industries.
3. Safe and reliable
The system operates in a closed environment, without open flames (fuel/gas type requires standardized combustion system), and the thermal oil is not easy to vaporize, avoiding the risk of high-pressure explosion of steam boilers;
Equipped with multiple protection devices such as over-temperature, over-pressure, and low liquid level, the safety is significantly improved.
4. Wide range of application
It can provide a continuous heat source of 30ºC-350ºC, and can adapt to different fuel types (such as electricity, gas, fuel oil, biomass, etc.) to meet the needs of diverse scenarios.
5. Easy installation and maintenance
Compact structure, small footprint, no need for complex chimneys or water treatment equipment (steam boilers require water softening devices), short installation cycle;
Daily maintenance mainly involves replacement of thermal oil, inspection of circulating pumps, etc., and is easy to operate.
Thermal oil boilers are widely used in the following industries with their stable high-temperature heat source and flexible temperature control capabilities: Chemical industry: heating for polymerization, distillation, concentration, crystallization and other processes; Food industry: baking, frying, sterilization, chocolate tempering and other production lines; Building materials industry: hot pressing of artificial boards, deep processing of glass, drying of tiles, etc.; Textile printing and dyeing industry: fabric shaping, dye heating, drying and other processes; Pharmaceutical industry: extraction of traditional Chinese medicine, synthesis of western medicine, sterilization of medicinal packaging, etc.; Other fields: rubber vulcanization, drying of lithium battery materials, carbon fiber molding, etc. Thermal oil boilers have become the core equipment in the field of industrial heating with their high efficiency, safety and precision, and are especially suitable for scenarios that require high temperature and stable heat sources.
