Working principle of explosion-proof heater for heat transfer oil furnace: For electric heating oil furnaces, heat is generated and transmitted by electric heating elements immersed in heat transfer oil. Using heat transfer oil as the medium and a circulation pump, the heat transfer oil is forced to undergo liquid-phase circulation, transferring heat to one or more heat-using devices. After being unloaded by the heat-using devices, it returns through the circulation pump to the heater, absorbs heat again, and transfers it to the heat-using devices. This cycle repeats, achieving continuous heat transfer, raising the temperature of the heated object to meet the process requirements of heating.
The heat transfer oil furnace electric heater equipment directly inserts the electric heater into the organic carrier (heat transfer oil) for direct electric heating, and uses a high-temperature oil pump for liquid-phase circulation to transport the electrically heated heat transfer oil to the heat-using equipment, then returns from the outlet of the heat-using equipment to the heat transfer oil heating furnace for electric heating, forming a complete circulating electric heating system. The electric heating heat transfer oil furnace uses a digital temperature controller for temperature control, with over-temperature alarm, low oil level alarm, and over-pressure alarm functions.
The heat transfer oil furnace is also called an organic heat carrier heat transfer oil heating furnace, commonly known as a heat transfer oil boiler, with the official name being hot oil furnace. It is a new type of electric heating thermal energy equipment that uses coal, oil, or gas as fuel and heat transfer oil as the circulating medium for heat supply. The heat transfer oil furnace refers to a new type of thermal energy conversion equipment where the heat-carrying working medium is high-temperature heat transfer oil (also called heat medium or heat carrier). Its capacity is usually expressed in "MW" (megawatts), and the old unit is also expressed in "ten thousand kilowatts/hour" or "ten thousand kilocalories/hour", i.e., "104kcal/h". The advantage of the heat transfer oil furnace lies in its "high temperature and low pressure" and stable operation, which is why it is widely used.
In industrial use, the heat transfer oil furnace explosion-proof electric heater is mainly used for heating crude oil and natural gas, as well as the processing, storage, and transportation of mineral oil. Refineries use heat transfer oil to preheat cold materials, and it has been successfully used for electric heating in solvent and extractant evaporation devices in the lubricating oil manufacturing process. Compared with steam heating, heating with a heat transfer oil furnace has advantages such as uniform heating, simple operation, safety and environmental protection, energy saving, high temperature control accuracy, and low operating pressure. In modern industrial production, it has been widely used as a heat transfer medium.
