What Is Furnace?

Furnace one part of the engine for the heating process. Its use has been widely applied in many industries such as ceramics, metal extraction, oil refineries or in chemical plants as heat sources for fractional distillation columns, and many more. Commonly used fuels are natural gas, fuel oil, wood, coal, and electricity (only in a few cases if they consume low electricity costs). In induction burners and the use of electric fuel to melt steel and cast iron while using fuel oil for melting non-ferrous raw materials. Meanwhile, you can find out more @ furnacebuzz.com.

The important thing about the efficient use of the furnace lies in the complete combustion of a fuel with minimal excess air. Burners operate with relatively low efficiency (as low as 7 percent) when compared to other combustion equipment such as boilers (with efficiencies of more than 90 percent). This is caused by high operating temperatures in the furnace. For example, a furnace that heats materials to a temperature of 1200 degrees C will emit flue gas at temperatures of 1200 C or more which results in significant heat loss through the chimney. The dimensions of the furnace and the ability to produce heat can be determined based on the calculation of its functions and needs. For example, a furnace for electricity generation needs, it requires a large dimension. Because to produce steam through a boiler requires a large amount of thermal energy.

The material of the furnace is also determined in accordance with the needs and what energy will be used either using a wall made of SS plate with ceramic fiber insulation or using a fire-resistant brick wall. Combustion stoves are broadly divided into two types based on heat generation methods: combustion stoves that use fuel, and electric stoves that use electricity. While the combustion furnace is also classified into several parts, the type of fuel used, how to load raw materials, how to transfer heat and how to reuse waste heat. However, in practice, it is not possible to use this classification because the furnace can use various types of fuels, different ways of loading materials into the furnace.
