But what exactly is a furnace? And how does a furnace accomplish the task of heating? The word furnace comes from the Greek word ‘fornox,’ which means an oven. Typically, ancient furnaces were made out of clay or bricks, and the fuel used for heating was coal or wood. Furnaces are amongst the oldest form of heating devices and were used extensively for a wide range of purposes like cooking and providing heat. Modern furnaces are highly advanced in technology and use a wide array of materials for fuel. Modern furnaces use petroleum products like diesel or LPG, electricity, or induction mechanism as fuel for heating. Modern furnaces are highly energy-efficient, have a low cost of operation, and are easy to maintain as compared to traditional coal furnaces.
Application of Furnaces
Today, furnaces are used for many purposes like industrial, commercial, and even domestic. In industries, furnaces are used as a heating source for boilers. But what is a boiler? A boiler is a closed vessel in which liquid (mostly water) is heated, and the heated liquid is then used for various processes or applications like steam generation, centralized heating, chemical processes that require heat, cooking, etc. Industrial furnaces mostly use diesel or LPG as a fuel, but there have been recent developments wherein electrical and induction furnaces are also used for industrial purposes. Another example of a furnace used in industries is steel plants. Steel plants require a huge amount of heat energy for the smelting of iron ore. This is done in huge blast furnaces, which typically use coal as a fuel source. These are just two of the examples where furnaces are used in industries. There are many industries that use furnaces for heat generation, and every industry requires a different amount of heat generation, depending on the use.
The second application of furnaces is in commercial spaces. In cold countries, commercial indoor spaces like malls, hotels, auditoriums, apartment buildings, etc., require centralized heating. A centralized heating system is a heating system in which heat is generated in one spot and distributed to other rooms through a ventilation system. A centralized heating system is much more energy-efficient, cost-effective, easy to operate, and has less maintenance as compared to individual room heating. In a centralized heating system, a furnace is used to generate heat,and that furnace is connected to a boiler where water is heated or boiled, depending upon the requirement. Once the water is boiled or heated, the hot water/ steam is passed through coils throughout the building, and the heat energy of the hot water/steam is transferred to the room through a radiator, and heating is achieved.
The last application of furnaces is in domestic uses. Furnaces are used domestically for generating heat, hot water, or even for cooking. Mostly, electric or induction furnaces are used for domestic purposes as the amount of heat required is not large.
Fuels Used in Furnaces
Depending upon the application and amount of heat required, furnaces use various types of fuels. The most commonly used furnaces are :
• Oil Furnace
These types of furnaces are typically used in industrial applications where the amount of heat generation is high. Diesel is the most preferred fuel for these types of furnaces as it is cheap and easily available.
• Gas Furnaces
These are other types of furnaces typically used in industries. LPG or CNG gas is the most preferred fuel for these types of furnaces.
• Electric Furnaces
These furnaces are highly efficient and use electricity as a source of fuel. These furnaces are mostly used for domestic purposes where the head requirement is less.
• Induction Furnace
These are the most modern types of furnaces that use the principal of induction heating for heat generation. These are highly efficient and are the most preferred ones for domestic purposes.
