Industrial Electric Boiler | Boiler Factory Direct Sales

Industrial electric boiler is a large-scale boiler equipment that uses electricity as energy and is widely used in various industrial production fields. The following is a detailed introduction to industrial electric boilers:

1. Definition and classification

• Definition：Industrial electric boilers are boiler equipment that uses electricity as energy and provides a large amount of heat source. It can be heated by electric heating tubes or electromagnetic induction principles.
• Classification：
  • According to the heating principle：traditional electric boilers are heated by electric heating tubes, while new electric boilers are heated by electromagnetic induction principles.
  • According to the installation method：they can be divided into packaged and bulk boilers.
  • Other classification methods include flue gas flow method (fire tube type, water tube type), boiler placement method (vertical, horizontal), purpose (industrial boiler, power station boiler), pressure level (low pressure, medium pressure, high pressure, ultra-high pressure), etc.

2. Working Principle

The main working principle of industrial electric boilers is to convert electrical energy into thermal energy through electric heating elements (such as electric heating tubes or electromagnetic induction coils), and then heat the water or heat-conducting medium in the boiler to reach the required temperature or generate steam to meet the needs of industrial production or heating.

Electromagnetic induction heating: Some high-efficiency industrial electric boilers use electromagnetic induction heating technology, which rectifies AC into DC through a high-frequency electromagnetic heating system, and then converts DC into high-frequency high-voltage electricity through a conversion module. High-frequency and high-voltage currents generate high-speed alternating magnetic fields in the coils, and the surface of the iron container cuts the alternating magnetic lines to generate eddy currents. The eddy currents cause the iron atoms at the bottom of the container to move irregularly at high speed, collide and rub against each other to generate heat energy, thereby achieving direct heating of the water. This method reduces the loss of heat during conduction and improves thermal efficiency.

Resistance heating: Another common heating method is resistance heating, but its thermal efficiency may be slightly lower than that of electromagnetic induction heating. However, by optimizing the design and material selection of resistance heating elements and strengthening insulation measures, the thermal efficiency of some resistance-type industrial electric boilers can also be close to or reach 98%.

3. Application fields

Industrial electric boilers have been widely used in many fields due to their high efficiency, environmental protection and stability:

Chemical production: Provide a stable and controllable high temperature environment to meet the reaction requirements in chemical production.

Food processing: Used for food heating, steaming, drying and other processing to ensure the quality and taste of food.

Printing and dyeing industry: Provide a high temperature and high pressure environment to promote dye penetration and improve printing and dyeing effects.

Pharmaceutical industry: Ensure the stability and safety of drugs during processing and meet the high standards of the pharmaceutical industry.

Other fields: such as metallurgy, building materials, papermaking, rubber, etc., all require industrial electric boilers to provide stable and efficient heating effects.

4. Advantages and Disadvantages

• Advantages：
  • Environmentally friendly and pollution-free: Since electricity is used as energy, no harmful gases and smoke are produced.
  • High energy efficiency conversion rate: Some high-tech boiler manufacturers can achieve an energy efficiency conversion rate of 98%.
  • Simple operation: convenient power control, easy to achieve automation and intelligent management.
  • Easy installation: small footprint, no chimney and fuel storage space required.
  • Quiet operation: Compared with other fuel boilers, electric boilers make less noise during operation.
• Disadvantages：
  • High operating cost: The relatively high cost of electricity may lead to an increase in overall operating costs.
  • High maintenance requirements: The circuit system is complex and requires regular inspection and maintenance to prevent circuit aging and fire risks.

5. Industry development trends

With the advancement of environmental protection policies and the adjustment of energy structure, industrial electric boilers will play a greater role in the clean energy supply of heating. At the same time, with the continuous development of information technology, Internet of Things technology and AI technology, industrial electric boilers will develop in the direction of automation and intelligence to improve operating efficiency and safety. In addition, with the popularization and application of new energy technologies, new energy boiler products such as electric boilers and molten salt boilers with heat storage functions will also receive more attention and development.
