In the reformer of petrochemical industry, the heat insulation effect of aluminum silicate fiber module is remarkable, which is mainly reflected in the following aspects:

I. Low thermal conductivity

Aluminum silicate fiber module has very low thermal conductivity, which makes its thermal insulation performance excellent. At 400℃, the thermal conductivity is less than 0.1 W/m k; At 600℃, the thermal conductivity is less than 0.15 w/m k. This low thermal conductivity can effectively reduce the heat transfer, keep the temperature in the furnace stable and reduce the heat loss.

II. Significant energy-saving effect

After using the aluminum silicate fiber module, the surface temperature of the furnace body is significantly reduced. The test results show that the surface temperature of the furnace wall is reduced from 271.0℃ to 119.3℃ on average after using the module. This not only reduces the surface heat dissipation of various parts of the furnace body, but also improves the energy utilization efficiency and reduces the production cost.

III. Good thermal stability

Aluminum silicate fiber module has excellent thermal stability and thermal shock resistance, and can withstand severe temperature fluctuations. This characteristic can ensure the structural stability of the module and reduce the cracks and heat leakage caused by thermal expansion and contraction during the frequent start-stop and temperature change of the converter.

IV. High overall sealing performance

After installation, the modules will expand in different directions and squeeze each other to form a seamless whole. This seamless structure further improves the heat insulation effect, reduces the heat loss, and also avoids the local overheating problem caused by cracks.

V. Simple construction and long service life

The installation of aluminum silicate fiber module is simple, and there is no need for complicated oven drying and maintenance procedures. It can be put into use after installation, which greatly shortens the construction period. In addition, it has high chemical stability, can resist the corrosion of chemical media and prolong its service life.

VI. Suitable for various working conditions

The classification temperature range of aluminum silicate fiber module is wide, from 1050℃ to 1400℃, which can meet the application requirements of reforming furnace under different working conditions. It can provide stable heat insulation effect in both high temperature section and middle and low temperature section.

VII. Summary

In the reformer in petrochemical industry, aluminum silicate fiber module is an ideal thermal insulation material because of its low thermal conductivity, good thermal stability, high overall sealing and simple construction, which can significantly improve the thermal insulation effect, reduce heat loss and improve energy utilization efficiency.
