What is an industrial oven?
At Procesni, we are proud of our innovative solutions, which will enable you to process materials such as iron or glass with the help of industrial ovens. Industrial ovens constructed according to your wishes, with efficient technological solutions and high energy standards or simply on a turnkey basis, will ensure that all the wishes and needs that arise in your industry will be met.
But first – what is an industrial oven? An industrial oven is a heated chamber that is used for a range of different heat treatment processes. They operate at extremely high temperatures and can be used for both small or large volume applications. The most common heat sources for an industrial oven are hot water, gas, and electricity, and these heat sources are often introduced into the oven via forced convection. When building an industrial oven, one must make sure that there is sufficient air flow guaranteed. The air needs to flow successfully from the air supply duct to the return duct. The pattern of the air flow can differ depending on the type of industrial oven and there are a number of common air flow patterns. Last but not least, all industrial ovens must be isolated so there are no energy losses in the process of heating.
In general, industrial ovens are frequently used for heat treatment of glass or metal
Our industrial ovens serve high-temperature processing of various raw materials. All raw materials can be found in liquid or solid state, and kilns are used in a wide variety of industries, including steel industry, glass industry, ceramic and chemical industries, as well as bricks and non-ferrous metals industries. Very frequently ovens for industry are used for heat treat of metal and glass. The industrial ovens we manufacture, serve to thermally transform and improve the structure of products, as well as to change their properties, such as tempering, normalization, masonry, sintering, nitriding or baking. In addition, our furnaces also allow heating before rolling, forging or drawing.
- Industrial ovens can be divided into different groups according to different criteria,
- technological purpose (melting, heating, heat treatment, sintering, drying),
o heat source (gas, fuel oil, coal, electricity, without external source),
o according to the shape of the working chamber (cave, line, circular, tunnel, chamber),
o according to heat consumption from waste gases (recuperative, regenerative, without heat exchanger).
We offer different types of industrial ovens
In the company Procesni we offer two different types of industrial ovens, which can be further divided into two subtypes:
- Industrial ovens for heating below 600 degrees Celsius
o Chamber oven for heating below 600 degrees Celsius
o continuous oven for heating below 600 degrees Celsius
- Industrial ovens for heating above 1000 degrees Celsius
o Chamber oven for heating above 1000 degrees Celsius
o continuous oven for heating above 1000 degrees Celsius
Industrial ovens for heating below 600 degrees Celsius: they are designed to heat various products to the prescribed temperature. In doing so, we want to ensure even heating of the products, which we succeed with the help of strong mixing of the atmosphere, when it is provided by circulating fans. The heating time in the industrial oven, of course, depends on the material we are heating. Because we want to operate as economically as possible, we also insulate the industrial ovens – they are insulated with stone wool. In addition, industrial ovens are equipped with their own ceiling and walls, which serve for the supply and exhaust of circulating air.
Industrial ovens for heating above 1000 degrees Celsius: we also built these stoves with the idea that they are as economical and environmentally friendly as possible. They are consist of a steel housing, and we also took care of proper insulation. The type of insulation is selected according to the atmosphere (reduction or oxidation), temperature and type of oven (continuous or chamber ovens). Insulation can be made of various temperature-resistant ceramic wool (up to 1260 ° C, 1430 ° C or even up to 1600 ° C) or fireclay bricks of various shapes and qualities and fire-resistant concrete.
Even in the case of these industrial ovens, we want to ensure evenly secretion, with the help of a suitable number of high-speed burners. The flue gases emitted into the atmosphere of the furnace from the burner mouth during combustion form a pulse that mixes the atmosphere due to the high speeds. In very high temperature ovens, where the operating temperature is above 1200 ° C, radiation is the main transmission tool. Therefore, in such industrial ovens we use special radiation burners that allow heating of large radiation surfaces - ceilings and walls.
Not only highly efficient, but also nature-friendly
Last but not least, our client needs are on the top priority list for us, but we also care about our environment. Therefore, we make sure that our industrial ovens are in compliance with all EU standards in this area. In 2010, Directive 2010/75 / EU was adopted, replacing seven existing (above-mentioned) directives in the field of industrial pollution. As envisaged by the old directive, the new one provides for the constant renewal of authorizations ̶ both due to technological changes and changes in legislation that are expected to occur due to the development of new best available techniques and lower limit values that will be achieved with it.
