A thermal oil furnace is an efficient heat energy device. Below is a detailed analysis of it:

I. Definition and Working Principle

Thermal oil furnace, also known as an organic heat carrier furnace or heat 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

The gas is transferred to a heat transfer oil for heating, and then the heated heat transfer oil is transported through pipes to the equipment or process that requires heating, for effective heat transfer.

Part Two: Structure and Composition

The basic components of a thermal oil furnace include a burner, flue gas pipes, a thermal oil circulation system, and heating equipment. Among them, the burner is responsible for the combustion of fuel and the generation of high-temperature flue gases; the flue gas pipes convey the high-temperature flue gases to

Thermal oil undergoes heat exchange; the thermal oil circulation system is responsible for transporting the heated thermal oil to the heat-using equipment, where it returns to the electric thermal oil furnace for reheating via the outlet of the heat-using equipment, forming a complete circulating heating system; heating

Equipment that heats using thermal oil to transfer heat energy.

Section 3: Technical Features

High Temperature, Low Pressure: The operating temperature of the thermal oil furnace is generally high, usually above 200°C, but the operating pressure is relatively low, which makes its 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, reaching the desired temperature in a short time, thus enhancing production efficiency.

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

Four: Application Fields

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

Building Materials Industry: Used for drying of gypsum boards, protection and curing of concrete components for prefabrication, tile molding, drying of decorative materials, and heat for asphalt felt production lines.

Road Construction Projects: Used for asphalt heating, dissolution, asphalt storage tanks, asphalt concrete, and heat preservation for emulsified asphalt.

Metallurgy, Machining, and Casting Industries: Used for degreasing tanks, Dewar vessels, pickling tanks, cleaning tanks, electroplating tanks, Lüyang plate oxidation tanks, electrode manufacturing, shower heat treatment equipment, phosphating equipment, baking machines

Room drying, sand core drying, varnish spraying and drying, assembly handling equipment heating, etc.

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