Thermal Oil Electric Heater [1] is a direct-flow special industrial furnace that uses coal, heavy oil, light oil, combustible gas or other combustible materials as fuel and thermal oil as heat carrier. It uses a circulating oil pump to force liquid phase circulation, transfers heat energy to the heat-using equipment, and then returns to reheat. Thermal oil, also known as organic heat carrier or heat transfer oil, has been used as an intermediate heat transfer medium in industrial heat exchange processes for more than fifty years. Organic heat carrier boiler is a new type of special boiler that uses heat transfer fluid as the heating medium. It has the characteristics of low pressure and high temperature operation. With the development of industrial production and the advancement of science and technology, organic heat carrier boilers have been continuously developed and applied. Although the working pressure of organic heat carrier boilers is relatively low, the temperature of the heat transfer fluid inside the furnace is high, and most of them are flammable and explosive. Once leakage occurs during operation, it may cause fire, explosion and other accidents, even resulting in casualties and property losses. Therefore, great attention must be paid to the safe operation and management of organic heat carrier boilers. Thermal Oil Electric Heater is a new type of special industrial furnace that is safe, efficient, energy-saving, low-pressure (under normal pressure or lower pressure) and can provide high-temperature heat energy. It uses thermal oil as the heat carrier, and circulates the heat carrier through a hot oil pump to transfer heat to the heat-using equipment.
The electric heating thermal oil furnace system consists of an explosion-proof electric heater, organic heat carrier boiler, heat exchanger (if any), on-site explosion-proof operation box, hot oil pump, expansion tank, etc., combined into a skid. Users only need to connect the power supply, inlet and outlet pipes of the medium, and some electrical interfaces to use.
Working Principle
For the thermal oil heater, heat is generated and transmitted by the electric heating element immersed in the thermal oil. Using thermal oil as the medium and a circulating pump, the thermal oil is forced to undergo liquid phase circulation, transferring heat to one or more heat-using equipment. After being unloaded by the heat-using equipment, it returns through the circulating pump to the heater, absorbs heat again, and transfers it to the heat-using equipment. This cycle repeats, achieving continuous heat transfer, raising the temperature of the heated object, and meeting the heating process requirements.Functional Features
