Industrial Heating Systems And Methodologies

Industrial heating systems combine the technologies necessary to provide adequate heat to a determined industrial production process, assuring the quality product at the end, maximizing productivity and minimizing overall costs. Industries utilize the heating system for manufacturing processes. Knowing how to choose which heating system and method are appropriate for the process can help in enhancing product quality.

The effectiveness of a heating system can be determined by its potential to comply with the quality requirements in the complete manufacturing process of a required product. These heating systems include all the elements and technologies needed to heat or melt a required outcome. It should be capable enough to manufacture the quality product with high standards and with low energy consumptions. 

Types Of Heating Systems

Convection air heating systems

Convection air heating is a type of heating system that involves the circulation of warm air through a heater. The air, in this case, is heated by an electrically operated fan placed over a boiler or furnace. This boiler or furnace may be a water-based type or an oil-based one. Some types of boilers and furnaces are already equipped with such systems. One of the good things about convection air heating systems is that they are very safe compared to other heating systems. There are not too many risks involved.

Infrared heating systems

These are ideal for high-speed manufacturing processes where a demand for a precise temperature is required. Infrared heating systems are gaining popularity as they are simple and economical to use. The basic theory of Infrared heating systems is the heat radiating from an electrically heated source. These heat rays are absorbed by the objects and move objects and thus transfer heat from one area to another. Infrared panels used can be made from quartz panels, sheathed elements, or lights to UV wavelength lamps. The use of Infrared heaters is ideal when the radiant light energy can reach the part surface.

Induction heating systems

The induction heating systems are the best way to heat any object or area with much lower energy consumption. This is due to the heating coil designs and other advances in technology. The induction heating systems are so efficient that they produce the most accurate temperatures and retain them for long, even when the conditions are totally otherwise. The efficiency of the entire process heating system is dependent upon the thickness of the electrically charged layer that is induced into the surface of the metallic plate inside the coil. The thicker the coil and the thinner the layer, the greater the efficiency of the heating process. The coil may either be permanent or a temporary one depending on the requirements.

Resistance power heating systems

Resistance heating is a method for heating parts by exposing them to high frequency alternating magnetic fields. The alternating magnetic field causes heating because the magnetic field produced by the magnets creates a change in the current through a conductive heating component, usually an insulated wire. The current induced in the wire is referred to as alternating current, or AC. Most resistant heat systems have been designed with easy installation in mind, but there is one drawback, electrical currents can escape from the system to ground level. Copper wire that is too thick can actually reduce the amount of current that can pass through it to ground level, so designers have designed some units with thinner copper wire. This enables the electrical current to flow into the system easily, preventing ground leakage. With these systems, easy installation is a significant factor, but several other factors make a heat-resistant system a good fit for your application. 

In Nutshell

In heating, operations systems supply energy to transform materials like metal, plastic, rubber, cement, glass, and ceramics into various industrial and consumer products. Industrial heating processes include drying, heat treating, curing and forming, calcining, smelting, and other operations. When process requirements often change, the older heating systems can be modified or rebuilt to meet current design standards and increase throughput or effectiveness. Changes include new resources, increased energy efficiency in the heat zones and new control. All heating systems are based on one or a combination of four major energy sources, which includes fuels, electricity or steam. Industrial applications are diverse. When considering using an electric heater, the end-user should consider the specific application and design considerations. Factors such as control safety, flexibility, maintenance should be evaluated.
