The principle of the thermal oil furnace:
1. Fueled by coal, heavy oil, light oil, combustible gases, and other combustible materials, with thermal oil as the heat carrier.
2. Utilize a recirculating oil pump to force liquid-phase circulation, transferring thermal energy to the heating equipment and then returning it to the special industrial furnace for reheating in a direct current (DC) mode.
3. Thermal oil, also known as organic heat carrier or heat transfer medium oil, has been used as an intermediate heat transfer medium in industrial heat exchange processes for over fifty years.
4. An organic heat carrier boiler is a new type of special boiler that uses a heat-conducting liquid as the heating medium, featuring low pressure and high-temperature operation. With the development of industrial production and the advancement of science and technology, the organic heat carrier boiler has seen continuous growth and application.
5. Although the working pressure of an organic heat carrier furnace is relatively low, the temperature of the heat conducting fluid inside the furnace is high and most of them are flammable and explosive. In case of a leak during operation, it could cause fires and other accidents, potentially resulting in injuries or deaths and property damage.
Therefore, the safe operation and management of organic heat carrier boilers must be given top priority.
Based on the process characteristics of the thermal oil electric heating furnace, a high-precision digital display programmable temperature controller is selected to automatically initiate optimal process program parameters for PID temperature control. The oil heating furnace control system is a closed-loop negative feedback system, where the oil temperature signal detected by the thermocouple is transmitted to the PID stable control instrument, which drives a non-contact controller. It controls the output power of the heater by adjusting the duty cycle within a fixed period.
Features include:
Over-temperature alarm and automatic shutdown of the heating power supply.
2. Alarm for broken coupling and automatic disconnection of the heating power supply.
3. Over-pressure alarm, and automatic shutdown of the heating power supply
The working principle of the thermal oil heater is a new type of energy conversion equipment that is environmentally friendly. It uses electricity as its energy source, converting electrical energy into heat energy through electrical heating elements; it then forces the thermal oil to circulate within the system using a high-temperature oil pump, repeatedly heating it to continuously meet the heat energy requirements of the heating equipment; it also meets the requirements for process temperatures set in the production process and high-precision temperature control.
