Advantages of refractory ceramic fiber products applied to ethylene cracking furnace

     The temperature of the cracking furnace chamber is relatively high (1300℃), and the temperature of flame center is as high as 1350~1380℃. When choosing refractory insulation materials, the traditional lightweight refractory brick or refractory castable structure has high thermal conductivity and poor thermal shock resistance. This leads to overheating of the outer wall of the cracking furnace shell and large heat loss. As a new type of high-efficiency and energy-saving material, refractory ceramic fiber products have the advantages of good thermal insulation performance, high temperature resistance, thermal good shock resistance, good mechanical vibration resistance, and convenient for construction. It is the most ideal refractory insulation material in the world today.

     Compared with traditional refractory materials, refractory ceramic fiber products have below advantages.

     1. Higher working temperature

     With the development of refractory fiber production and application technology, refractory ceramic fiber products have achieved their serialization and functionalization. The product can meet the requirements of different grades of working temperature from 600℃ to 1500℃.  In terms of morphology, it has gradually formed a variety of secondary processing or deep processing products from the most traditional wool, blanket, and felt products to fiber modules, boards, vacuum formed parts, paper, fiber textiles and so on. Refractory ceramic fiber products can fully meet the needs of different application parts of industrial furnaces in various industries.

     Next issue we will continue to introduce advantage of refractory ceramic fiber products applied to ethylene cracking furnace.
