Variety of industrial ovens with sensors and different types of burners
Many people are asking themselves what is an industrial oven and what are they used for. Well, the answer to this question is relatively simple. Industrial ovens are basically heated chambers that are used for various industrial applications such as baking, curing, and drying parts, components or various products. These can be used for small or big volume applications, continuously with conveyor lines, in batches, and a range of different configurations, sizes, and temperatures. They are widely used in a number of industries such as food production, electronics, chemical processing, oil and gas, pharmaceutical, and automotive.
Quite often, industrial ovens are used in applications such as food productions, chemical processing, and electronics companies, where circuit boards are run through the conveyor oven to attach the surface mount components.
In our company, we offer a few types of different industrial ovens. They can be generally divided into two groups: chamber ovens and continuous ovens. Chamber ovens are widely used in steel, reheating, foundry, aluminum and ceramics industries. The main purpose of continuous ovens is to give the user the ability to control the speed and heat at which a part needs to be finished.
Ovens for heating products below 600°
These industrial ovens are designed to heat products to a temperature of up to 600 degrees Celsius. By vigorously mixing the atmosphere with circulating fans, uniform baking of the products is achieved. The heating time depends on the material being heated in the industrial oven. Because we want to minimize heat losses, we surrounded the oven with effective thermal insulation - glass wool. Temperature sensors are installed in the oven, more specifically in the inlet and outlet channel for each zone. There are two types of these industrial ovens available:
- chamber industrial ovens below 600 degrees: Products are loaded onto carts in a chamber oven that are being pushed on a cart into the oven through single or double door. Larger carts are powered and are usually placed on tracks. The size of the ventilation systems and the manner with which the products are loaded onto carts impacts the speed of heating and the evenness of products. The specific energy use is dependent on the ratio between cart weight and the weight of products. The negative pressure zone of the oven has a built-in type of burner, heating the oven.
- Continuous industrial oven below 600 degrees: The oven is intended for colour curing after powder coating. The dyed pieces travel through the oven, which is in fact a heating tunnel. Transport takes place with the help of a chain transporter on the oven ceiling outside of the heated area. Heating is done through a combination of infrared heaters that heat the surface quickly, as well as ventilation systems quipped with channel type of burners. Infrared heaters are placed throughout the oven interchangeably and also heat the side of the channel in the interim between two pieces. As a result, the outside surfaces are heated quickly as well. This method of curing/paint finishing is suitable for product with a large exterior surface. Products then travel along the other part of the oven, where the paint finishing process ends with the help of convection – with the help of the heated air circulating through the dryer, the infrared channel type of burner heats the air.
Ovens for heating products over 1000 degrees
These industrial ovens boast a highly durable steel housing and adequate insulation. It is carefully selected according to the atmosphere, temperature and type of power. Insulation can be made of various temperature-resistant ceramic wools (up to 1260 ° C, 1430 ° C or even up to 1600 ° C) or from fireclay bricks of various shapes and qualities and fire-resistant concrete.
- Chamber industrial oven over 100 degrees: In order to achieve the greatest possible uniformity in the heating of materials, burners are installed in the furnaces, which mix the atmosphere with a large pulse and in a certain area of the curve operate at least 70% or do not work. The temperature rises and falls along the curve. A special feature of such a furnace is the insulation, where it needs to be heated and cooled again every cycle and can represent a significant waste of energy.
- Continuous industrial oven over 100 degrees: The products travel through the furnace and heat up on their way. Transport through the furnace can be done either with trolleys, rollers, chain, brackets or crossbars. These furnaces are primarily used to heat bulk material. On the inlet side, the material enters the rotary drum, is heated there, and exits the drum through the end piece or through openings in the drum. Heating can be direct - the burner is in the center of the drum - or indirectly with burners in the jacket.
