What is a Industrial Heaters?

Industrial heaters are used to convert the energy of a fuel or another energy source to thermal energy in a specific system, process stream, or closed conditions. The process that thermal energy is transformed from an energy source to a system can be described as heat transfer.

Industrial heaters are used in various processes where the temperature of an object or process needs to be increased. For example, lubricating oil needs to be heated before it is fed to a machine, or a pipe might require heat tracing to prevent it from freezing in the cold. Most industrial heaters operate based on an electric source. Industrial electric heaters work by transforming electrical energy into heat. The heat is then transported to the process through numerous forms of heat transfer.

Classification of Industrial Heaters

Motor Parts | Linquip

There are many types of industrial heaters accessible in many varied shapes, sizes, and configurations. Industrial heaters can be described by their application, medium, fuel source, physical properties, or other particular type of heater.

Here, we have common types of heaters based on their application: immersion heaters, circulation heaters, duct heaters, and space heaters and room heaters.

Immersion Heaters

Immersion heaters are utilized in applications that require immersing the heater in the substance to be heated. These heaters are used to heat liquids in large containers, vats, and tanks. Immersion heater uses a direct heat transfer for heating liquids. It increases the speed at which the liquid arrives the desired temperature. These industrial heaters have been used fuel as their source of power; however, as the fuel price increased over the past few decades, they have shifted to electric power. Electric immersion heaters are much more environmentally friendly and transfer the heat promptly.

Immersion heaters usually work with various types of liquid properties and often need minimum maintenance. Some of these types of industrial heaters include:

  • Flanged heater
  • Over the side heater
  • Screw plug heater


Circulation heaters:

These heaters are also called inline heaters and are one of the several types of immersion heaters. This type of heaters includes a pump that helps the liquid flow through a closed pipe circuit. When the liquid enters the pipe, it becomes heated and then exits from the nozzle. Circulation heaters are available in a wide range of wattages.

Circulation heaters are employed primarily to heat moving, flowing, or circulating fluid currents. Fluid passes through the heater, which carries heat to the fluid stream. Any liquid or gas is usually acceptable for use with a circulation heater. Usually, circulation heaters are used as stock tank heaters, dry well heaters, livestock tank heaters, asphalt heaters, circulation tank heaters, and septic tank heaters.

Circulation heaters can be configured to accommodate direct heating of process fluids or be applied for indirect heating processes and systems.


Duct heaters

Duct heaters are utilized to heat flowing gas streams. They are installed in the center of a moving gas or air stream to heat the air as it moves within the heater.

A duct heater can also be utilized to heat an object as the air's thermal energy radiantly is transported to an object at the end of the flow stream. This indirect heat transfer method is useful for drying, baking, or preheating solid objects in an enclosed space.


Space Heaters and Room Heaters

Space heaters and room heaters are devised for use in restricted areas or spaces. They do not emit dangerous pollutants or toxic fumes and are generally portable.

The essential specification to be considered when choosing space heaters and room heaters are the primary fuel source. Options include electricity, liquid fuels, gaseous fuels, wood, and solar hot water. Diesel, fuel oil, kerosene, gasoline, and waste oil are samples of liquid fuels. Gaseous fuels involve both natural gas and propane. Wood-burning space heaters and room heaters may utilize pellets, logs, and other combustible solid products.


Basics of Industrial heaters

AC Motor Types | Linquip

There are various AC motor types available on today’s market, each with slightly different operating characteristics and output capabilities. Despite the many different varieties and details the manufacturer guidelines might go into, the critical difference is attributed to the procedure of rotors construction, as this will often dictate their range of practical capabilities. AC motors are generally divided into two main categories based on the rotor type: a) induction motors, b) synchronous motor. An induction motor is a specific type of AC motor assembly that relies on a spinning, electrically charged rotor to create an EMF (Electro Magnetic Field) around a stator, thus producing the vital alternating current AC motor can then transform into mechanical energy. The synchronous motor refers to motors whose rotating speed is equal to the synchronous speed. The synchronous AC motor typically has other components fitted, known as slip rings, which provide current transmission between the motor’s rotating and fixed elements. AC motors can also be divided based on their power source into single-phase and polyphase (three phases).

Performance Specification of Industrial Heaters

As a general rule, the conversion of electrical power into mechanical power takes place in the rotating part of an electric motor. In AC motors, the rotor does not acquire electric power by conduction, but they receive electric power by induction. As a matter of fact, an induction motor can be treated as a rotating transformer, i.e., the primary winding is stationary, and the secondary is free to rotate. AC motors count on a device called an alternator to generate this alternating charge direction. An alternator is a specialized type of electrical generator, in which an EMF is typically performed when electricity is transferred through a spinning shaft, which itself turns around or within a set of static wire coils. The resulting EMF switches direction, or polarity, as the rotor turns in relation to the stator. Because an EMF created by a charged rotor turning on a fixed axis will switch polarity at set points relative to the stator, the periodic reversal of current direction in an AC motor happens at regular and predictable intervals.
