Generally, the thermal insulation of large heating devices usually adopts the method of ceramic fiber module + blanket. On the one hand, the application of the structure is mature and the thermal insulation effect is remarkable. On the other hand, large equipment means that there is sufficient space reserved for the thermal insulation layer, which is usually not less than 330mm thick; Moreover, the thermal insulation structure of ceramic fiber module is required to have a regular sense of space. If the furnace wall fluctuates greatly or the surface is uneven, the firmness and tightness will be greatly reduced, so it is not recommended.
Such as curved surface high-temperature equipment, or when the thermal insulation requirements are not high, ceramic fiber blanket is often used for thermal insulation. For example, high-temperature pipeline insulation is generally wrapped with several layers of ceramic fiber blanket and bound with heat-resistant steel wire; Another example is the insulation of lime kiln, which mostly adopts the structure of vertical tiling of large ceramic fiber blanket.
Ceramic fiber board is more powerful. If the wind speed is high, or it needs to be placed in the flame to stop the fire, or it needs refractory materials with rigidity and load-bearing capacity, ceramic fiber board is the best choice. For example, the wind shield on the top of the arch tunnel kiln can effectively balance the temperature in the open fire furnace, save coal consumption and improve the firing quality of red bricks; The addition of backing plate in pouring furnace lining greatly reduces heat loss, saves energy and reduces consumption, improves product quality and prolongs the service life of furnace body.
Of course, for the thermal insulation of some special and relatively important high-temperature parts, we have launched ceramic fiber special-shaped parts, which can be customized according to user requirements and use environment measurement. However, the relative cost will be higher, which is not suitable for wide range use.
In addition to the following conventional materials, the company has introduced super insulation materials, such as nano insulation panels, aerogel felt, refractory castables for furnace castings, and ceramic fiber cloth, tape and packing for high temperature protection, providing a series of high temperature insulation solutions for users.
