A thermal oil furnace is an efficient heat energy device; here is a detailed explanation of it:


I. Definition and Working Principle

Thermal oil furnace, also known as an organic heat carrier furnace or hot oil furnace, is a new type of thermal energy equipment that uses coal, oil, or gas as fuel and thermal oil as the circulating medium for heating. Its working principle involves burning fuel to produce high-temperature flue gas, which heats


Heat is transferred to the thermal oil for heating, which is then transported through pipes to the equipment or process requiring heating, effectively transferring thermal energy.


II. Structure and Composition

Basic components of a thermal oil furnace include the burner, flue gas pipe, thermal oil circulation system, and heating equipment. The burner is responsible for fuel combustion and the generation of high-temperature flue gas; the flue gas pipe transmits the high-temperature flue gas to


Thermal oil is used for heat exchange; the thermal oil circulation system is responsible for transporting the heated thermal oil to the heat-using equipment, and then returning to the electric thermal oil furnace through the outlet of the heat-using equipment to be reheated, forming a complete circulating heating system; heating


Equipment that heats using thermal oil to transfer heat energy.


III. Technical Features

High temperature low pressure: The working temperature of thermal oil heaters is generally high, usually above 200°C, but the working pressure is relatively low, which makes the operation more stable and safe.

High temperature control accuracy: The thermal oil furnace uses a digital temperature controller for precise temperature control, featuring over-temperature, low oil level, and over-pressure alarms, ensuring accurate temperature control.

Fast heating speed: The thermal oil furnace heats up quickly, capable of reaching the required temperature in a short time, thereby enhancing production efficiency.

High thermal efficiency: Heat transfer oil, as a heat medium, boasts excellent thermal conductivity and chemical stability, allowing for stable operation at higher temperatures with high heat transfer efficiency.

Section 4: Application Fields

Thermal oil furnaces are widely used in various industries, including but not limited to:


Building Materials Industry: Used for gypsum board drying, concrete component curing protection and prefabrication production, tile molding, decorative material drying, and hot rolling in asphalt felt production lines.

Paving Engineering: Used for asphalt heating, dissolution, asphalt storage tanks, asphalt concrete, and heating insulation of emulsified asphalt.

Metallurgy, machining, and casting industry: metal degreasing pools, Dewar bottles, acid washing tanks, cleaning tanks, electroplating tanks, Lüyang board oxidation tanks, electrode manufacturing, shower heat treatment equipment, phosphate treatment equipment, baking machines


House, sand core drying, varnish spraying and drying, and heating for assembly treatment equipment.

Food Industry: Used for bread baking equipment, biscuit baking equipment, candy production equipment, grain drying equipment, oil extraction and refining equipment for edible oils, distillation pots, autoclaves, and heating for conveyor belt dryers.
