Heaters

Heaters is derived from the Turkish word 'rezistans'. Resistance is an element that produces resistance to electric current, that is, it opposes electric current. Resistors that resist electric current cause an increase in the current (Amperes) value in the system and are elements that generate heat. In other words, we can think of resistors used as heat generators that convert electrical energy into heat energy. Resistors used as heat generators are frequently used in industry, manufacturing, and even household appliances. The areas of use of resistors used in many fields of industry can be listed as follows:

In the plastic sector: clamp heaters, plate type heaters, pellet heaters, nozzle heaters, hot runner (spiral) heaters

In liquid, fluid, or gas heating: flanged heaters, headed type (three-phase) heaters, rod heaters, sleeve heaters are used.

In drying and ventilation processes: serpentine heaters, cassette type heaters, pipe type heaters are used.

The types of heaters in industrial furnaces vary according to the operating temperatures. Standard 304 Cr-Ni sheathed heaters are used around 250-300 °C, while incoloy800 series outer sheathed tube heaters are used between 300 °C and 600 °C, and incoloy825 series should be preferred above 600 °C. Instead of tube sheathed heaters, heaters made of spiral wound Cr-Al or Cr-Ni alloy helically wound bare furnace wires should be used.

In chemical processes, immersion type polypropylene-headed heaters are generally preferred. Immersion heaters also use many different outer sheaths depending on the chemical the heater will work in. Some of these are teflon sheathed heaters, titanium sheathed heaters, AISI316 stainless steel sheathed heaters, incoloy825 sheathed heaters, lead sheathed heaters.

Engineering knowledge and design are very important in the manufacturing and design of heaters. The long-lasting and process-appropriate selection of heaters directly affects the health and quality of your process. Heaters must be carefully selected and designed according to the surface loads of heaters according to the place of use, environment, and temperature value.

When manufacturing a heater, all details from the outer sheath to the insulation material to be used inside must be carefully selected. For example, completely different materials should be used between a heater that will work in water and a heater that will work in an oven. Materials used in heater manufacturing can be listed as follows: Magnesium oxide (MgO) with high electrical insulation and heat conduction coefficient, the resistor wire that performs the main heat production process by resisting electricity, the insertion or terminal outputs that allow energy supply, stainless outer sheath. All these materials should be selected according to the place of use.

In general, the heater is selected in the form of a spiral resistor wire in the center according to the desired wattage and the length of the heater. Terminals that will supply energy to the end parts are mounted in spiral form under appropriate conditions. Then, the outer stainless sheath is prepared in the form of a tube of the desired length, and with special filling machines, the heater wire is centered in the tube and magnesium oxide filling is filled around it. Magnesium oxide is in powder and fluid form when first filled. Then, the filled heater is passed through rolling machines for rolling process. In this process, magnesium oxide is transformed from powder to solid and compressed form, the resistor wire in the center is fixed, and the internal structure of the heater is made to conduct heat as quickly as possible. Then, after the rolled heaters are in the form of bars, they are subjected to annealing process for shaping, and annealing process is done for softening in order to shape the outer stainless sheath. The annealed heater is now ready to be shaped as desired. The shaped heater is welded to the appropriate assembly equipment or assembled to be suitable for use. Another important point to be paid attention to in heater production is that the leakage current and insulation resistance values of the produced product under high voltage should be at suitable levels. If these values are not at the appropriate level, heaters can cause problems in a very short time in the place of use. A heater produced in accordance with all standards will always satisfy its user.

How Do Heaters Work?

Heaters are electrical components that convert electrical energy into heat energy. The working principle involves the resistance of the heater and the generation of heat as electric current overcomes this resistance.Essentially, the electrical resistance within a heater impedes the free flow of electrons. As electrons move through the heater, they encounter resistance, resulting in an energy loss. This energy loss is converted into heat.The heat within the heater varies depending on the structure of the resistance material and the speed of current flow. The higher the resistance of the heater, the more resistance the electric current encounters, thus producing more heat.Heaters are typically made in the form of metal wires or film layers. Metal wires carry electric current while creating resistance and generating heat. Film heaters, on the other hand, are produced in thin film layers and mounted on surfaces. Heat is generated as the current passes through the film layers.In this way, heaters convert electrical energy into heat for various applications such as heating, cooking, industrial processes, and current control in electronic circuits.

Principle of Operation of Heaters

Heaters work by converting electrical energy into heat, a process governed by electrical resistance. The principle of operation relies on the fact that when electric current passes through a resistive material, it encounters opposition, which generates heat. This is the fundamental process by which heaters create warmth. Here are the key points explaining how heaters work:

• Electric Current and Resistance: When an electric current passes through a resistive material, the resistance of the material causes friction, converting electrical energy into heat. The higher the resistance, the more heat is produced, making the material's resistance an essential factor in heat generation.
• Conversion of Electrical Energy to Heat: The heater's electrical element (usually made of materials like nickel-chromium, tungsten, or steel) is designed to resist the flow of electric current, generating heat in the process. The heat generated then radiates from the element and heats the surrounding space or medium.
• Heat Distribution: Once the heat is generated by the resistance of the material, it is transferred to the air, water, or surface intended to be heated. The efficiency of this heat transfer is influenced by the material, the shape of the heating element, and any insulating materials used to prevent heat loss.
• Temperature Regulation: To maintain a consistent temperature, modern heaters incorporate temperature control mechanisms, such as thermostats, which monitor the heat output and automatically adjust the power supplied to the heating element. This prevents overheating and ensures the heater operates only when needed.
• Safety Features: Many modern heaters include safety features such as automatic shut-off switches, thermal cutoffs, or fuses, which prevent overheating and protect both the heater and its users from potential hazards.
