There are about 7 billion people living on the planet. With this many people, it is no doubt that we are bound to scatter around on every continent. Some places have a relatively nicer climate with the sun being present all year round, and there is no need to worry about the cold. However, for those who live in the polar regions or places with higher latitude, that is a completely different story. With blizzards and frost being pervasive, it is very crucial for humans to find a way to keep themselves warm. Fortunately, we no longer need to burn the woods like our ancestor did before. We have invented a system to help us combat the frigid temperature, the heat systems.
So what are heat systems? The heat systems, or heating systems, are a mechanism which is utilized to keep the temperature at an acceptable level within an area. The heating system can be applied to a lot of places. The most notable example of the heating system is the heating for households. The system will generate the heat to keep the house temperature at a comfortable and stable degree while outside might be snowing and the temperature drop to below zero. But not just the household needs the heating systems, in the industries, the heating systems are also proven to be very important as some materials require the heat to be processed.
There are several types of the heating systems utilized in the field of industries. Each of them comes with it’s unique trait. There are two methods when it comes to the way the heat is transferred - the direct and indirect method. For the direct method, the heat is generated within the material itself. And for the indirect method, the heat is transferred from another source to the material through the process of convention, radiation, and conduction. The following are some of the examples for the industrial heating systems:
In the combustion of fuel based heaters, people will burn the solids or gases to generate the heat. This heat will later be transferred to the materials in either the direct method or indirect method. The materials that people usually choose as the fuel are oil, coal, natural gas, wood chips, charcoal, ethanol and cellulose. If adding the oxygen of fresh air during the process of heating, it will enhance the combustion. When processing in the direct method, the heating gas and the material will come into contact. However, when processing in the indirect method, there is a set of confined vessels which is used to keep the materials from direct contact with the heating gases.
In electrical heaters, there is an electric current which is used to heat up the materials. Just like the other types of heaters, there are direct and indirect ways to heat the materials. In the process of direct method, the electric current is directed directly through the materials. In the process of the indirect method, the heat generated by the electric current is transferred to the materials through an additional separate heat element.
In some manufacturing facilities, some special type of heaters is required due to the process of manufacturing or the traits of the products. Heat recovery and exchanger systems is one example. In this system, it is equipped with a heat exchanger which is used to transfer the heat from one process to the other.
These days, the boilers are the most common way to generate the energy required for the manufacturing facilities. The boilers are a relatively perplexing system compared to the other type of heaters. The steam which is generated by the boiler is generated through the burning of fuel. By using the steam, we can make sure that we process the materials in a way which is less toxic than the other heaters, much easier to transport, and the cost is relatively low when compared to other systems.
These days, for the majority of North American families, it is the furnace which provides the heat required for the families. A furnace will burn the gas or use the electricity to generate the heat. The heating process begins as the heated air is blown through the ducts. The ducts will then utilize the air registers to distribute the warm air to every room.
