Infrared heating high-temperature reaction kettle

Adopting infrared heating, the operating temperature can reach 300-600°C. Stable operation with adjustable temperature, originally developed in China.

The high-efficiency and energy-saving infrared technology was vigorously promoted nationwide by the Ministry of Energy as early as the 1970s. Our company took the lead in developing and elaborately designing infrared technology in 1987, and reasonably applied it for heating and thermal insulation of vessels such as reactors, distillation kettles, enamel kettles, polymerization kettles, drying equipment and pipelines. It has been widely adopted by domestic and foreign large and medium-sized enterprises including Nanjing Chemical Plant, Tianjin Beacon Coatings Co., Ltd., Xuzhou Pesticide Factory, BASF Dyes, ICI Polyurethanes, CTCI Overseas Corporation, Jilin Chemical Group, Baling Petrochemical Corporation, Dalian Dye & Additive Plant, National University of Defense Technology, and has won consistent praise from users.
The far-infrared electric heating device features large heating area, steady and rapid temperature rise, uniform heat release, convenient temperature control with separate upper, middle and lower section regulation. The temperature of the kettle wall inside the reactor is easy to control. It has no side effects on materials in the reactor and will not cause carbonization of materials. It operates with low noise and no pollution, and has a long service life (over 30,000 hours) with remarkable energy saving effect (over 28%). The heater temperature can be arbitrarily set within the range from ambient temperature to 800℃. To meet user demands, our company has upgraded the heating equipment to make the whole heating device meet explosion-proof requirements, which has passed the appraisal by the National Quality Inspection Center for Explosion-proof Electrical Products. It completely solves the explosion-proof problem that users have long worried about and cannot be solved by other heating methods.
With the growing global awareness of environmental protection, the "far-infrared electric heating device" solves serious ecological pollution problems caused by traditional heating methods. Therefore, it is praised as a "green heating device" by industry professionals in China.

Comparison Table of Energy-saving Performance between Thermal Oil Heating and Far-infrared Heating for Reactors
——Case study of a 3800L water-containing reactor
No.	Heating Method	Thermal Oil Electric Tube Heating	Far-infrared Heating	Remarks
No.	Category	Thermal Oil Electric Tube Heating	Far-infrared Heating	Remarks
1	Design Power	168KW	120KW
2	Power Distribution	8 groups of electric heating tubes	3-section heating: upper, middle and lower
3	Thermal Response Time	It takes 1.5 hours and consumes 250 kWh to heat 1 ton of thermal oil in the jacket to 280℃	The outer wall of reactor reaches 400℃ after 30 minutes of power-on, consuming 42 kWh
4	Actual Operating Power	Full load operation at 160KW	Only the middle & lower sections (84KW) meet process requirements
5	Power Consumption per Batch	1764 kWh per batch	814 kWh per batch	53% power saving
6	Safety Standard	Non-explosion-proof	The whole heating unit complies with explosion-proof requirements with valid explosion-proof certificates
7	Hygiene & Environmental Performance	Diphenyl mixture is added into thermal oil; oil vapor leakage at high temperature is toxic and harmful to human body	Zero pollution & low noise during operation; no material carbonization or coking; no extra thermal insulation required after installation
8	Applicable Reaction Temperature	Suitable for reaction heating below 300℃	Capable of heating materials up to 700℃ with adjustable temperature setting
9	Normal Wear & Tear	Thermal oil is prone to carbonization; oil and electric tubes must be replaced at least once a year	No additional cost within 3 years; easy installation and maintenance	Cost saving: 10,000 CNY/year
10	Heat Transfer Principle	Heat is transferred to materials inside reactor by heating thermal oil in the jacket	Electric resistance heating element generates heat; silicon carbide far-infrared radiation uniformly transfers heat to materials inside reactor
Conclusion of Comparison: Compared with thermal oil heating, far-infrared radiation heating achieves 53% energy saving, saving 950 kWh per batch of product. It also saves the cost of 1 ton of thermal oil, replacement of electric heating tubes and loss caused by shutdown maintenance every year. Thanks to rapid and stable temperature rise of far-infrared heating, users can increase production output, improve product quality and reduce labor intensity while optimizing working environment. In addition, the far-infrared heating device features reasonable structural design, attractive appearance, easy installation and operation, flexible temperature control (separate control for upper, middle and lower sections), and explosion-proof safety performance.
