How is industrial heat generated?


We are all aware that warm food stored in the refrigerator cools down and that warm food left out in a room cools down. This occurs as energy is transferred from the warm to the cold medium. The different types of energy are well known. Heat is one of the forms of energy that can move from one system to another due to a temperature difference. Heat is a type of energy that we are constantly exposed to. There’s heat from the sun (solar thermal) and heat from the earth (geothermal), but for this post, we’ll focus on industrial heat—heat used in manufacturing and modifying goods. We’ll define the industrial heating, methods of industrial heat generation, and the industries that use them, if you need any.

What is industrial heating?

Industrial heat is basically a thermal energy that is used particularly to prepare or treat materials that are used to make manufactured goods. In the process of generating industrial heat, electrical energy is transformed into heat energy. It functions according to the Joule heating principle, which states that every electric heater’s heating element is an electrical resistor that converts electrical energy into heat energy. The active element in the majority of present-day electric heating devices is Nichrome wire, which is supported by ceramic insulators.

An evaluation of the required temperature, required heat output, and practical means of heat energy transfer is the first step in designing an industrial heating system. Industrial heat generation mechanisms are made up of a circuit that combines the technologies required to efficiently supply heat to a specific industrial production process. In turn, it ensures the quality of the finished product while increasing productivity as well as lowering energy costs.

Low temperature (up to 400 °C), medium temperature (between 400 and 1,150 °C), and high temperature (above 1,150 °C) are the three broad categories that can be used to describe industrial heat.

Industrial Conduction, convection, and radiation are the three methods by which heat can be transferred. A temperature difference is a requirement for all types of heat transfer. Furthermore, in all types of heat transfer, heat is transferred from a high temperature to a lower temperature.

What is industrial heat used for?

Electric heaters serve as the foundation for the generation of industrial heat. Almost everything we use on a daily basis, including textiles, cement, steel, computer chips, plastic, and glass, depends on them for energy. The following are some particular industries that demand industrial heat in one way or another:

  • Oil and gas processing: An electric heater is an ideal solution for processing oil and gas. Heating is used for many applications, including highly viscous oils, gas dehydration, gas sweetening, etc.
  • Petrochemical industries: Petrochemicals need high temperatures to preserve their viscosity in both process applications as well as outdoor environments. Electric heating maintains the viscosity required for petrochemicals when being operated in extreme temperature conditions.
  • Food & Beverage: Industrial heating has been essential to all commercial F&B processes for many years. Fryers, ovens, grills, and other heating appliances used in food processing have been continuously needed by the food industry.
  • Plastic and packaging industry: Packaging mechanism frequently makes use of component heaters as well as process heaters. By using industrial heat, three different types of packaging can be accomplished: Form-fill and seal, portion packaging, tamper-proof packaging
  • Industrial water heating: It is mandatory to maintain the operating temperature of industrial water to avoid malfunctioning in the manufacturing process. Within the manufacturing facility, it is used for processing, transferring, heating, and cooling a product. In order to process industrial water for precise manufacturing processes, industrial heaters are used.

In addition to this, there are numerous applications where industrial heat is crucial for different manufacturing processes. Please click APPLICATIONS to view them.

Generation of industrial heat

Depending on the particular industry and its requirements, many ways are used to generate industrial heat. A few typical techniques for producing industrial heat include:

  • Combustion

Combustion is one of the most popular ways to produce heat in industrial settings. The exothermic chemical reactions that take place as the fuel burns produce heat during combustion. In addition to heating buildings and other structures, this heat can be used to power engines and provide energy.

Industrial heat generation with electric heating is highly prevalent. Electric resistance heating components are used, which turn electrical energy into heat. In circumstances where combustion is undesirable, electric heating is frequently favored since it is a clean and effective way to produce heat. Through conduction, convection, radiation, or a combination of these, a heating element is used in indirect heating to produce heat.

  • Solar and Geothermal

In the solar process, sunlight is focused onto a receiver using mirrors or lenses. They utilize solar thermal power to absorb the heat and make steam. The steam is then used to drive electricity-producing turbines.

Geothermal process utilize heat from the interior of the Earth to create steam, which is then used to produce electricity. Deep holes in the Earth’s crust are drilled in order to obtain hot water or steam, which is then utilised to drive turbines.

  • Heat exchanger systems

Heat exchanger systems rely on a heat exchanger to transfer heat from one process material to another. They effectively produce heat that is utilised in waste heat recovery units, chemical processing systems, food processing systems, and vehicle radiators.

In general, the technique utilised for generating industrial heat is determined by the particular requirements of the sector as well as the accessibility of resources like fuel and electricity.

How Marathon helps industries by generating industrial heat?

Almost every manufacturing sector has seen a significant increase in the use of industrial heating in recent years. Because of this, more industries now use electric heating throughout their production processes. Furthermore, it has become increasingly popular for nations to produce low-carbon electricity from renewable sources. We manufacture electric heaters that follow to all these sustainability guidelines while simultaneously producing low-carbon industrial heating. Heat generated by electric heating is 100% efficient for a user as the energy is completely converted to heat.

The following are some of the advantages of generating industrial heat using electric heating methods over other methods:

  • Precise distribution of heat energy along with regulation of temperature.
  • Capacity to reach temperatures that are difficult to reach through chemical combustion.
  • Industrial heat can be precisely applied at the exact point a process requires it.
  • Enhanced productivity and creation of a product of higher caliber at a generally lower cost of operation.
  • Advanced instrumentation and controls allow for remote management of the amount of industrial heat to be generated.

In conclusion, a number of techniques, such as combustion, electric heating, solar thermal, and geothermal, can be used to produce industrial heat. Each method has pros and cons, and the choice of method depends on the particular industrial application. In the future, it’s likely that we will observe a shift towards the use of cleaner and more effective methods of generating heat due to the rising demand for sustainable and renewable energy sources. Our heaters provide stable industrial heating and temperature control for various manufacturing processes.
