“Precise insulation selection.
Impulses for the evenness of the product.
Radiant burners for higher temperatures.”
High-temperature ovens are equipped with a frame and appropriate insulation.
The type of insulation is carefully selected based on the atmosphere (reduction or oxidation), temperature and the type of oven (continuous or chamber).
Insulation can be done by using different types of refractory ceramic wool (up to temperatures of 1260°C, 1430°C or even 1600°C) or grog brick of different shapes and qualities as well as refractory concrete.
The evenness of products is guaranteed through the right amount of high-speed burners.
The smoke fumes that are released into the atmosphere from the mouth of the burner act as an atmosphere mixer due to the high speed of release and the types of impulses.
With extremely high-temperature ovens, where the work temperature can exceed 1200°C, radiation is the main transmission tool. This is why with such ovens we use special radiant burners. They enable the heating of large radiant surfaces e.g. ceilings and walls.
Ovens can be heated either directly – products can come in contact with smoke gases – or indirectly, where the heating of the products occurs indirectly (such as through the use of radiant pipes) in the required oven atmosphere (reduction, oxidation). The unique characteristic of high-temperature ovens is the use of recuperative and regenerative burners that allow for greater energy efficiency.
