It is suitable for users with higher requirements on environment and quality in automobile, communication, electronics, hardware, chemical, printing, plastic, building materials, food, medicine and other industries.
2. Gas-fired tunnel furnace heated by gas
Advantages: Low cost in later period.
Disadvantages: The temperature requirement is not high about 150 degrees.
Suitable for hardware, ceramics, textile printing and dyeing, spraying coating, chemical industry, pollution treatment and other industries on the temperature and environmental requirements are not high, gas source sufficient enterprises can consider using gas tunnel furnace operation.
3. Microwave tunnel furnace heated by microwave
Advantages: clean, sterilization, high temperature
Disadvantages: High energy consumption.
Suitable for: food, medicine, agricultural products, chemical and other industries of product medium internal drying and sterilization treatment of heating equipment.
4. Steam heated steam tunnel furnace
Advantage: Make full use of heat energy.
Disadvantages: Unstable steam source
Enterprises with steam sources can use steam power supply mode, suitable for the temperature requirements of the enterprise is not high.
5. Heat conducting oil tunnel furnace using heat conducting oil as medium
Advantage: High temperature
Disadvantages: large energy consumption, energy saving is not obvious. It is usually suitable for enterprises with low environmental requirements.
In addition, other methods such as coal burning, diesel burning and boiler burning are also adopted. In the current development of environmental protection and energy saving, it is not recommended to adopt heating methods such as coal burning, diesel burning and boiler burning in urban areas.
