Infrared heating reaction kettle

Heating by infrared radiation, with operating temperature ranging from 300℃ to 600℃. Stable operation and adjustable temperature; it is the first of its kind domestically.

The high-efficiency and energy-saving infrared technology was vigorously promoted nationwide by the Ministry of Energy as early as the 1970s. In 2000, our company took the lead in developing and elaborately designing infrared technology, rationally applying it for heating and thermal insulation of vessels such as reaction kettles, distillation kettles, enamel kettles, polymerization kettles, drying equipment and pipelines, which has won consistent praise from users.

The far-infrared electric heating device features large heating area, stable and rapid temperature rise, uniform heat release and convenient temperature control. It supports segmented temperature control at upper, middle and lower sections. The temperature of the kettle wall inside the reactor can be easily controlled without any side effects on materials in the kettle. It operates silently with no pollution and long service life (more than 30,000 hours), achieving remarkable energy saving (over 28%). The heater temperature can be arbitrarily set from ambient temperature up to 800℃. To meet user requirements, our company has upgraded the heating equipment so that the whole heating device meets explosion-proof requirements and has passed the appraisal by the National Quality Inspection Center for Explosion-proof Electrical Products. It thoroughly solves the explosion-proof problem that users have long been concerned about and cannot be resolved by other heating methods.

Comparison Table of Energy-saving Performance between Heat Transfer Oil Heating and Far-infrared Heating for Reaction Kettles
Example based on a 4000L reaction kettle in actual operation:
No.	Heating Method	Heat Transfer Oil Heating	Far-infrared Heating	Remarks
No.	Item	Heat Transfer Oil 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 parts
3	Thermal Response Time	It takes 1.5 hours and consumes 250 kWh to heat 1 ton of heat transfer oil in the jacket to 280℃	The outer wall of the reaction kettle reaches 400℃ after 30 minutes of power-on, power consumption: 42 kWh
4	Actual Operating Power	Full load operation at 160KW	Only the middle and lower sections (84KW) are required to meet process requirements
5	Power Consumption per Batch	1764 kWh per batch of materials	814 kWh per batch of materials	53% power saving
6	Safety Standard	Electric heating tubes are not explosion-proof	The whole heating assembly complies with explosion-proof requirements with valid explosion-proof certificates
7	Hygiene & Environmental Performance	Diphenyl mixture is added into heat transfer oil; oil vapor leakage at high temperature is toxic and harmful to humans	No pollution, no noise during operation; no carbonization or coking of materials. No additional thermal insulation needed after installation
8	Applicable Reaction Temperature	Up to 300℃	Capable of heating materials up to 700℃ with adjustable temperature setting
9	Regular Maintenance Cost	Heat transfer oil is prone to carbonization; oil and heating tubes need replacement at least once a year	No extra costs within 3 years, easy installation and maintenance	Cost saving: 10,000 CNY / year
10	Heat Transfer Principle	Heat transfer oil in the jacket is heated, and heat is transferred to materials inside the kettle via oil	Resistance heating elements generate heat when energized. Heat is evenly radiated to materials in the kettle through silicon carbide far-infrared radiation
