There are a variety of ways of constructing an industrial convection oven. But regardless of the method used, industries would always use a refractory ceramic board in the lining of the oven.
Three Main Methods of Installing Ceramic Board to Your Oven
Industrial oven manufacturers have the option to use a ceramic blanket, ceramic fiber module, or a refractory ceramic board to line the furnace. These materials are attached to the industrial convection oven using two distinct methods.
1. External Thermal Insulation: Builders would anchor or paste refractory ceramic boards between the shell of the oven and the cold surface of the furnace wall. This method is typically used on structures that require lightweight bricks or low temp ceramic fiber materials.
2. Internal Insulation: The ceramic board is attached to the hot surface of the industrial convection oven 's walls in this method. Ovens that are continuously operated or batch type kilns are ideal for this method as the effect of the thermal insulation will remain as long as the boards are attached well to the hot surface of the lining. Internal insulation reduces the heat loss while allowing the significant regenerative loss.
Internal insulation is the method that's most commonly used in industrial convection ovens now. It's because the process extends the working life of the fire-resistant layer and insulation material. It also saves energy and allows for total high thermal efficiency.
3. Intermediate Insulation: This method entails attaching the refractory board to the middle of the oven or kiln wall. It's admittedly not as effective as the previous two methods; thus furnace companies rarely use this method now.
Builders can utilize adhesives like Portland cement, silica gel, sodium silicate adhesive, and sulfate compound for the two methods.
There are ways to ensure your industrial convection oven is energy efficient and will last longer. Using a refractory ceramic board and correctly installing the material will ensure that investing in an oven is not wasted.
