A furnace is a place/room made of refractory bricks that can be heated with fuel or electricity and used to burn ceramic objects. The function of the furnace is to burn ceramic objects arranged inside it and burn it using special fuels (wood, coal, oil, gas, or electricity) until all the heat spreads and burns everything in the furnace.
Combustion or heat radiation takes place in the furnace or under the combustion chamber and excess smoke exits through the fire channel or furnace chimney. Hot circulation must be left evenly and freely around the object when it is burned. If at any time the fire stove is not working as it should, you can call the best furnace expert, namely the furnace repair Kenosha to check and repair it.
To get satisfactory combustion results, any type of furnace must meet several requirements, including:
- Can reach the desired temperature easily.
- The temperature of the entire furnace in the combustion chamber is evenly distributed.
- Efficient fuel consumption (saving).
- Long service life (durable).
- It has easy and inexpensive operating and maintenance procedures.
At present, various types of furnaces can be found both in ceramic craft centers (pottery), ceramic studios, and the ceramic industry. Some important factors to consider in choosing or designing a ceramic furnace are:
- Furnace type.
What is meant by the type of furnace is the circulation of the fire/the way the fire is, the shape of the furnace, the size/capacity and the fuel used.
- Furnace capacity.
Capacity is closely related to the productivity and volume of the furnace (combustion chamber), so it needs to be considered how the size of the furnace must be made.
- The final temperature you want to reach.
In designing the furnace, it is necessary to know the type of body of the ceramic object to be burned so that the raw materials for making the furnace also adjust. To be more efficient, combustion furnaces are selected that can reach high temperatures.
- Desired combustion conditions.
The conditions of combustion to be achieved (oxidation, reduction or neutral) must be determined in order to determine the shape of the combustion chamber, burner, and damper.
- Types of items to be burned.
Ceramic clay material that is burned can be divided into terracotta/earthenware, stoneware or porcelain. Therefore, we need to determine the type of furnace, size, and fuel to be used.
- Fuel type.
The type of fuel to be used needs to consider environmental conditions, whether with wood, oil, gas, coal, or electricity.
- Furnace location
The location of the furnace must pay attention to environmental conditions, in the city, in the suburbs, the factory yard, garage, and others.
- Plate size/shelves
The size of the refractory plate must also be calculated to match the size of the plates that are already on the market. Various types of furnaces can be used, ranging from the simplest to the most modern, over time. Classification of furnace types can be distinguished based on shape, mode of operation, heat contact, use of the inventor’s name, circulation of fire, and the fuel used.
