The furnace is a kitchen that receives heat from fuel for combustion. In the furnace, there is a fire gate at the bottom as the base of the fuel and around it, there are kettle water pipes attached to the walls of the combustion chamber as heat receivers from the fuel by radiation, conduction, and convection. Furnace furnaces are used to melt metals for the manufacture of machine parts and also to heat materials and change their shape or change the properties of materials. In this furnace the flue gas from the fuel which then comes into direct contact with the raw material, so the type of fuel is important. It’s because some fuel will not be tolerated sulfur. In the meantime, if you’re looking for furnaces that can be used at homes instead of factories, we recommend you to check out the best furnace brands for residential use.
Then, solid fuels will produce particulate matter which will interfere with raw materials placed in the furnace. This is the reason almost all furnaces use liquid fuel, gas or electricity as the energy input. Induction and arc furnaces use electricity to melt cast iron and steel. For non-ferrous raw materials, fuel oil uses melting furnaces. Furnaces that are burned with fuel oil use almost entirely furnace oil, mainly for reheating and heat treatment of materials.
There are several variants of the furnace, such as:
Muffle Furnace. Muffle furnaces are kilns where the subject matter and all combustion products including gas and ash are isolated. Then carried out the development of electric heaters in this type with high temperatures, elements, and electrification that developed in developed countries, so that the muffle furnace is now changing to electricity quickly.
Salt bath furnace. For this type of modern salt bath furnace, it is used for various heat treatment applications.
Vacuum furnace. A vacuum furnace is a type of furnace that can heat materials, usually metal, at very high temperatures and carries out processes such as sintering, brazing, and heat treatment with high consistency and low contamination.
Fluidized-bed furnace. Fluidized-bed furnaces are square or cylindrical combustion furnaces and there is also a furnace Length of Chamber and Room Reaction for gas distribution to a fireplace or supply of air explosions.
