Kiln insulation and energy saving, how to choose insulation bricks?

Choosing the right insulation brick is an important step to improve the insulation effect of the kiln and achieve energy saving. Here are some suggestions

Thermal conductivity: The lower the thermal conductivity of the insulation brick, the better the insulation performance. Therefore, materials with lower thermal conductivity should be selected. Common insulation brick materials include expanded vermiculite, expanded perlite, aluminum silicate fiberboard, etc.

Density: The density of insulation bricks is also an important consideration. Generally, the lower the density, the lighter the brick, and the better the insulation performance. But be aware that too low density may lead to a decrease in strength, and a balance needs to be struck between insulation performance and mechanical strength.

High temperature resistance: The inside of the kiln usually reaches high temperatures, so it is crucial to choose insulation materials that can withstand high temperatures. Materials such as aluminum silicate fiberboard and expanded vermiculite perform well at high temperatures.

Corrosion resistance: If there are corrosive gases or liquids such as acids and alkalis in the kiln, choose insulation materials with good corrosion resistance to extend the service life of the insulation bricks.

Size and shape: The size and shape of the insulation bricks should be able to adapt to the design requirements of the kiln, ensure tight installation and reduce the formation of thermal bridges.

Environmental protection: In today's society, environmental protection is becoming more and more important. Choosing renewable or recycled materials and insulation bricks that meet environmental standards can help reduce environmental impact.

Based on the above, the selection of insulation bricks should be based on the specific kiln design and operating conditions. It is recommended to consult the insulation material supplier or engineer for more accurate advice.
