Comparison of Costs and Advantages between Electric Heating Thermal Oil Furnace and Other Boilers
Dari Electric recommends for you
Electric heating thermal oil furnace is a new type of special industrial furnace that is safe, energy-efficient, low-pressure, and capable of providing high-temperature heat. It uses electricity as the energy source and thermal oil as the heat carrier, utilizing a circulating oil pump to force liquid circulation, transferring heat to the heat-using equipment, and then returning to be reheated in a direct-flow special industrial furnace. This cycle repeats, achieving continuous heat transfer and raising the temperature of the heated object to meet the process requirements. Due to its advantages of high temperature (standard type 220°C, high-temperature type 250°C, 300°C, 350°C) and low pressure (0.3-0.5MPa), and its heating temperature can be precisely controlled (±1°C, custom-made up to ±0.1°C), it is an indispensable auxiliary equipment in modern industrial production.
As can be seen from the above table, the operating cost of electric heating thermal oil furnace is 2.3 times that of coal-fired boiler, 1.7 times that of gas-fired boiler, and 0.8 times that of oil-fired boiler. However, considering that the first three types of boilers cause serious environmental pollution, require dedicated personnel for operation and maintenance (monthly labor costs), and need special warehouses for fuel storage, as well as involving fire safety issues and explosion risks, and their control accuracy is far lower than that of electric heating boilers, the advantages of electric heating boilers are very obvious.
Advantages of electric heating boiler:
(1) Compact and scientific appearance design: The product adopts a cabinet-style design, with a beautiful appearance and compact internal structure, making it an ideal choice for saving space.
(2) Unique internal structure design: The electric heating tube is connected to the furnace body with a flange, facilitating replacement, maintenance, and repair.
(3) Precise temperature control system: Users can adjust the temperature from room temperature to 200°C as needed, making it more user-friendly. Temperature control accuracy ±0.1°C
(4) One-step electric control system: The boiler operating system is fully automatic, and all control parts are integrated on a single computer control board. To operate, simply connect water and electricity, press the on/off key, and the boiler will automatically enter full automatic operation mode, safe and worry-free.
(5) Multiple interlocking safety protection functions: The product is equipped with a vent to prevent pressure buildup and explosion accidents; it also has low water level protection, which automatically stops the boiler when water supply is interrupted, preventing dry heating that could damage the heating elements or cause burnout. The leakage protector ensures the safety of operators and equipment; even in case of circuit short circuit or leakage due to improper operation, the boiler will automatically cut off the circuit, promptly protecting the operator and control circuit safety.
(6) Using electricity is more environmentally friendly and economical: Electric energy is pollution-free and more environmentally friendly compared to other fuels. Using off-peak electricity can significantly reduce equipment operating costs.
