Recommended Structure for All-Fiber Furnace Linings

Currently, most industrial furnaces use full ceramic fiber linings, except for furnaces with high wear, strong airflow, or complex chemical conditions. Ceramic fiber is preferred due to its high-temperature resistance, lightweight, and ability to reduce surface temperature, lower fuel consumption, improve product quality, and extend furnace lifespan.

1. Layered Blanket Structure

Full ceramic fiber linings can adopt a layered blanket structure. Each layer is selected based on the furnace temperature gradient to balance cost and insulation efficiency.
Installation usually involves welding steel anchors to the furnace wall and fastening ceramic fiber blankets with screws.

Stainless steel mesh is often applied on top to prevent sagging.

Multi-layer manual installation is challenging, especially when using more than three different fiber types, as ensuring quality and forming an integrated structure becomes difficult.

2. Combination of Modules and Flat Blankets

Pre-compressed elastic modules compensate for fiber shrinkage, enhancing lining tightness and overall flatness.
Spray-on curing agents on the working surface prevent debris shedding and extend service life.
Advantages of the Module + Blanket Structure:

Reduces fuel consumption and increases output

Lowers furnace surface temperature

Extends furnace service life

Minimizes combustion losses
