Process Heating System for Industrial Uses

Process heating is a critical step in manufacturing processes, used to heat materials in the production of metals and non-metals such as glass, cement, rubber, plastic products and ceramics. A variety of process heating system are available to meet different needs. These include electric fans, space heaters and other heat-producing equipment designed for industrial, commercial, and residential applications. These units are available in various configurations depending on the application; they can either employ active or passive systems for controlling the temperature of the heat generated.

Industrial process heating, also known as process air heating (PAH) and process hydronic radiant heating (PHH). It is a significant means of heating in industrial applications. It is achieved by using high-pressure steam or employing a combination of steam and water for the purpose. Process heating is an energy-efficient method commonly used to heat the entire manufacturing plant. Hence, including all areas in between the processing units.

Types Of Process Heating System

We can break the process heating system into three fundamental categories. Depending on the process heating application, system sizes, configurations, and operating functioning systems vary widely across the industry.

Fuel Based Heating System

Fuel-based process heating uses energy from the fuel itself. From some sort of combustion process to raise the temperature and is then transfer either directly or indirectly to the material. Such as to melt steel for making metal, to conduct heat in solar-powered furnaces to boil water and other purposes. The energy source may be coal, wood, gas, oil, or some renewable energy, such as geothermal or hydroelectric power. Most modern fuel-based processes run on stored diesel or other nonrenewable energy.

Most fuel-based process heating employs a boiler to heat water, air, or a solution in a furnace. A gas or liquid fuel is pass through a burner, which consists of a fan or blower. This fan generates or radiates thermal energy, which heats the air or liquid to a specific temperature. This process of applying heat is generally refer to as convection heating. This heating process is use in many different industrial applications, especially those where the temperature is a factor in production, storage, or processing. Such industrial process heating results in substantial increases in the temperature of the work environment. As well as in operating costs for thermal engines.

Electric Based Process Heating

In an electric-based process, heating system are often known as electrotechnology and use electric currents or electromagnetic waves to heat materials. Electric-based process heating units can be use for many different types of procedures, such as drying, degreasing, cleaning, deodorizing, filling, lubricating, melting, forming, printing, polishing, and just about any type of mechanical operation that needs to be conducted at high temperatures. Indirect electric heating methods use these three methods to heat an elementary substance, which transfers the heat to the workpiece by either conduction, convection, radiation, or any combination.

Direct electric heating methods generate heat within the workpiece by transmitting an electric current through the substance, inducing a current in the material, or by exciting atoms and/or molecules within the material with electromagnetic radiation. Different levels of electromagnetic fields are produce during the manufacturing process, depending upon the end product that is to be creat. The smaller the area of a manufacturing process, the less likely it is that the electrical currents use to conduct heating will generate harmful electromagnetic fields.

Steam Based Process Heating

Steam-based systems use steam to provide heat to the materials directly or indirectly. This process heating is a very efficient way to produce heat in a fraction of its time with other sources. Steam has several favorable properties for heating applications. The steam-based heating process introduces heat into the process by direct injection or indirectly through a heat transfer device. Can transfer large quantities of latent heat from the steam efficiently at a consistent temperature, useful for many process heating applications. Steam holds the important amount of energy on a unit mass basis, units per pound.

Direct steam heating systems introduce steam into gases or liquids. Indirect systems use a heat exchange in which steam is cool and condense in tubes; the heated pipes supply heat to the gases and liquids. Steam allows several advantages in heating operations, such as high-level heat capacity, ease of transport, low toxicity and cost. A variety of by-product fuels can generate it.

The Endnote

Industrial process heating is also an important contributor to overall energy consumption in industries. Industrial heating systems are the combination of a circuit that combines the technologies necessary to provide heat effectively to the industrial production process, guaranteeing the quality of the end product, maximizing productivity, and minimizing energy costs.

The efficiency of a heating system can be determine by its capacity, which complies with the quality requirements in the product’s manufacturing process. These systems include all the technologies needed to heat or melt a specific product.
