Any heating system will have two main components, the heat generator that works and the object that is to be heated. Heat will be transferred from the generator to the object by a heat transfer technology. These technologies are based upon one or a combination of conduction, convection and radiative heat transfer mechanisms. Let’s look at all of the four heating technologies.
Industrial Heating Systems can also replace boilers as they get old. This way, you can enjoy extended service life out of your system, which could translate to substantial savings on your part. For industries that need constant heating up of their entire worksite, an industrial heater is the best option since it provides the exact amount of heat to keep the area warm. Since the system uses little electricity to achieve sufficient heat for the site, it is also cost-effective and environmentally friendly.
Steam-based heating systems
Steam-based heating systems involve high temperatures to vaporize steam into the mechanical process either by injection, direct, or indirectly via a heat exchanger. Large amounts of latent heat generated by steam can efficiently transfer to a large volume of circulating fluid, valid for most mechanical process heating applications. These systems provide an effective and economical means of heating air and water for domestic use and industrial processes such as washing, drying, etc. In addition, these types of systems are generally safe to operate, have a high-efficiency factor, and are highly adaptable to most installation situations.
One of the unique features of this type of heating system is that, unlike conventional furnace designs, there is no hot air furnace where burning fuel (gasoline, coal, etc.) or combustion products (wood, gas, etc.) result in exhaust gases. In the case of the exhaust gases from the top of furnaces and a steam-based boiler, this phenomenon is often called ‘blowing out of the gases because it causes a strong odour and is also unhealthy for those living nearby.
Because of this unique characteristic, steam-based heating systems deliver much better results concerning both fuel economy and health safety. The effectiveness depends on the temperature of the liquid used and the design of the burner. The temperature of the liquid used can either be constant or variable depending upon the particular application’s requirements.
Fuel based heating systems
Fuel-based process heating systems include kilns, boilers, kiln chillers, ovens, steam boilers, low-temperature burners, and high-temperature burners. The kilns creating the steam in the last section are an example of a fuel-based process heating system. The oven is a device that breaks solid materials to make them easy to mold. The metal grinders, such as those used in making bowls, plates, and other kitchen utensils, are also examples of fuel-based process heating systems.
Electric process heating systems
Electro-heating, also called electrothermal, is one of the latest technologies in providing heating systems to industrial, commercial, and residential applications. Electro-heating uses electric currents to transfer heat from one volatile compound to another through an electrochemical reaction. Electro-heating systems are not new. Electric heat technology has been in existence for hundreds of years.
Also, to regulate the heat inside the room, electric heating systems use several types of temperature control devices. A typical exchange consists of a series of copper tubes fitted in between two walls, which allows heat to be filtered into various layers of the room by bringing the warmer air closer to the surface of the walls. Other temperature control devices like thermostats are also found in such heaters.
Industrial Electric process Heating has emerged as the most commonly used process of heating in industrial setups. The primary reason behind this growing popularity is the increasing energy costs and the resultant reduction in the thermal mass. Industrial Electric process Heating systems include electric heat systems, such as Electric process air, gas, electric, oil and electric heating systems. This list includes almost all of the different types of Industrial Electric heat appliances available. These different types of Industrial Electric process Heating systems are further divided into several categories depending upon the applications and the nature of the requirements of the process being operated.
The industrial sectors require advanced heating technology because the contemporary manufacturing process involves high temperatures and limited time. Thus, industrial heating techniques have become indispensable in today’s rapidly changing world. Thermal bridging or blanket technique is one such method, where hot air or heat is trapped by a thin layer of ultra-fine blankets that have an evaporator above them and are placed in between the hot surfaces to serve as insulation. The heated air then passes under low-pressure air or gas for overcome the atmospheric pressure. The advantage of heating techniques over others is that heating of objects is done faster, and it has a long-lasting effect compared to other methods.
