Infrared heating high-temperature reaction kettle

Wuxi reactor adopts infrared heating, with operating temperature ranging from 300℃ to 600℃. It features stable operation and adjustable temperature, being an original domestic innovation.

The high-efficiency and energy-saving infrared technology was promoted nationwide by the Ministry of Energy as a key application back in the 1970s. Our company took the lead in developing and elaborately applying infrared technology to heating and thermal insulation of vessels including reactors, distillation kettles, enamel kettles, polymerization kettles and drying equipment & pipelines in 1987. The products have been widely adopted by large and medium-sized domestic and overseas enterprises such as 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 Additives Factory and National University of Defense Technology, winning consistent favorable comments from customers.

The far-infrared electric heating device features large heating area, stable and rapid temperature rise, uniform heat release and convenient temperature control with separate upper, middle and lower section regulation. The temperature of the kettle wall can be easily controlled, bringing no side effects to materials inside the vessel and avoiding material carbonization. It operates without noise or pollution, with a long service life (over 30,000 hours) and remarkable energy saving (over 28%). The heater temperature can be freely set from ambient temperature up to 800℃. To meet customer demands, our company has upgraded the heating equipment to fulfill explosion-proof requirements, which has been certified by the National Inspection Center for Quality of Explosion-proof Electrical Products. It thoroughly solves the long-concerned explosion-proof issue that cannot be addressed by other heating methods.

With growing global awareness of environmental protection, the far-infrared electric heating device resolves severe ecological pollution caused by traditional heating modes. Therefore, it is praised as a "green heating device" by domestic industry professionals.

Comparison Table of Energy-saving Performance between Thermal Oil Heating and Far-infrared Heating for Reactors
——Based on application data of a 3800L water capacity reactor
No.	Heating Method	Thermal Oil Electric Heating Tube Heating	Far-infrared Heating	Remarks
No.	Category	Thermal Oil Electric Heating Tube Heating	Far-infrared Heating	Remarks
1	Design Power	168KW	120KW
2	Power Distribution	8 groups of electric heating tubes	Three-section heating: upper, middle and lower
3	Thermal Response Time	It takes 1.5 hours and 250 kWh to heat 1 ton of thermal oil in 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 at 160KW	Only middle and lower groups (84KW) meet process requirements
5	Power Consumption per Batch	1764 kWh per batch	814 kWh per batch	53% power saved
6	Safety Standard	Not explosion-proof	The whole heating device meets explosion-proof requirements with relevant explosion-proof certificates
7	Environmental & Hygiene Performance	Diphenyl mixture added in thermal oil; toxic oil vapor leakage at high temperature is harmful to human	No pollution or noise; no carbonization or coking of materials; no extra insulation required after installation
8	Applicable Reaction Temperature	For reaction temperature below 300℃	Heating available up to 700℃ with freely adjustable temperature
9	Routine Wear & Tear	Thermal oil tends to carbonize; oil and heating tubes need replacement at least once per year	No extra cost within 3 years; easy installation and maintenance	Cost saving of 10,000 CNY per year
10	Heat Transfer Principle	Heat the jacket oil, then transfer heat to materials inside reactor via oil	Heat generated by resistance heating element is evenly radiated to materials via silicon carbide far-infrared emitter
Conclusion: Comparison of the two heating methods shows that far-infrared radiation heating achieves remarkable 53% energy saving compared with thermal oil heating, saving 950 kWh per batch. It cuts annual costs for 1 ton of thermal oil replacement, electric heating tube renewal and production downtime losses. With fast and stable temperature rise, far-infrared heating increases output and product quality, and improves labor intensity and working environment. Moreover, the far-infrared heating device boasts rational structural design, attractive appearance, convenient installation and operation, easy temperature control (separate upper/middle/lower regulation), explosion-proof safety and other advantages.
