The outstanding characteristics of CCEWOOL ceramic fiber are the keys to the transformation of industrial furnaces from the heavy scale to the light scale, realizing light energy saving for industrial furnaces.
With the rapid advances in industrialization and socio-economy, the biggest problems that arise are environmental issues. As a result, developing clean energy sources and energy-saving and environmentally friendly materials are extremely critical in adjusting the industrial structure and following the path of green development.
As a fibrous lightweight refractory material, CCEWOOL ceramic fiber has the advantages of being light, high temperature resistant, thermally stable, low in thermal conductivity and specific heat capacity, and mechanical vibration resistant. In industrial production and other applications, it reduces energy loss and resource waste by 10-30% compared with traditional refractory materials, such as insulation and castable. Therefore, it has been used in more and more extensive applications around the world, such as machinery, metallurgy, chemical industry, petroleum, ceramics, glass, electronics, households, aerospace, defense, and other industries. Due to the continuous rise of global energy prices, energy conservation has become a global development strategy.
CCEWOOL ceramic fiber has been focusing on energy conservation issues and research on new and renewable energies. With the eleven outstanding characteristics of ceramic fiber, CCEWOOL can help complete the transformation of industrial furnaces from the heavy scale to the light scale, realizing light energy saving for industrial furnaces.
Low volume weight
Reducing furnace load and extending furnace life
CCEWOOL ceramic fiber is a fibrous refractory material, and the most common CCEWOOL ceramic fiber blankets have the volume density of 96-128Kg/m3, and the volume density of CCEWOOL ceramic fiber modules folded by fiber blankets is 200-240 kg/m3, weighing 1/5-1/10 of lightweight refractory bricks, and 1/15-1/20 of heavy refractory materials. CCEWOOL ceramic fiber lining material can realize the light weight and high efficiency of heating furnaces, greatly reduce the load of streel structured furnaces, and extend the service life of the furnace body.
Low heat capacity
Less heat absorption, fast heating, and cost saving
Basically, the heat capacity of furnaces’ lining materials is proportional to the weight of lining. When the heat capacity is low, it means the furnace absorbs less heat and experiences an accelerated heating process during the reciprocating operations. Since CCEWOOL ceramic fiber only has 1/9 heat capacity of that of light heat-resistant lining and light clay ceramic tiles, which greatly reduces energy consumption during furnace temperature operation and control, and it yields significant energy saving effects especially on intermittently operated heating furnaces.
Low thermal conductivity
Less heat loss, energy saving
The thermal conductivity of CCEWOOL ceramic fiber material is less than 0.12W/mk at an average temperature of 400 ℃, less than 0.22 W/mk at an average temperature of 600 ℃, and less than 0.28 W/mk at an average temperature of 1000 ℃, which is about 1/8 of that of light monolithic refractory materials and about 1/10 of light bricks. Therefore, the thermal conductivity of CCEWOOL ceramic fiber materials can be negligible compared with that of heavy refractory materials, so the thermal insulation effects of CCEWOOL ceramic fiber are remarkable.
Stable performance under rapid cold and hot conditions
The thermal stability of CCEWOOL ceramic fiber is incomparable by any dense or light refractory materials. In general, dense refractor bricks will crack or even peel off after being heated and cooled rapidly several times. However, CCEWOOL ceramic fiber products will not peel off under rapid temperature change between hot and cold conditions because they are porous products composed of fibers (a diameter of 2-5 um) intertwined with each other. Moreover, they can resist bending, folding, twisting, and mechanical vibration. Therefore, in theory, they are not subject to any sudden temperature changes.
Resistance to mechanical shock
Being elastic and breathable
As a sealing and/or lining material for high-temp gases, CCEWOOL ceramic fiber has both elasticity (compression recovery) and air permeability. The compression resilience rate of CCEWOOL ceramic fiber increases as the volume density of fiber products increases, and its air permeability resistance rises accordingly, which means, the air permeability of fiber products decreases. Therefore, a sealing or lining material for high-temp gas requires fiber products with a high-volume density (at least 128kg/m3) to improve its compression resilience and air resistance. In addition, fiber products containing binder have greater compression resilience than fiber products without binder; therefore, a finished integral furnace can keep intact when being impacted or subjected to vibration from road transportation.
Anti-airflow erosion performance
Strong anti-airflow erosion performance; wider application
Fuel furnaces and furnaces with fanned circulation pose a high requirement for refractory fibers to have a certain resistance to airflow. The maximum allowable wind speed of CCEWOOL ceramic fiber blankets is 15-18 m/s, and the maximum allowable wind speed of fiber folding modules is 20-25 m/s. The resistance of CCEWOOL ceramic fiber wall lining to high-speed airflow decreases with the rise of the operating temperature, so it is widely used in the insulation of industrial furnace equipment, such as fuel furnaces and chimneys.
High thermal sensitivity
Automatic control over furnaces
The thermal sensitivity of CCEWOOL ceramic fiber lining is much beyond that of conventional refractory lining. At present, heating furnaces are generally controlled by a microcomputer, and the high thermal sensitivity of CCEWOOL ceramic fiber lining makes it more suitable for the automatic control of industrial furnaces.
Sound absorption and noise reduction; improvement on environmental quality
CCEWOOL ceramic fiber can reduce high-frequency noise of less than 1000 HZ. For sound waves under 300 HZ, its sound insulation ability is superior to that of regular sound insulation materials, so it can significantly relieve noise pollution. CCEWOOL ceramic fiber is widely used in thermal insulation and sound insulation in construction industries and in industrial furnaces with high noise, and it improves the quality of both working and living environments.
Reducing the load on the steel structure of furnaces and costs
Since CCEWOOL ceramic fiber is a kind of soft and elastic porous material, the expansion of which is absorbed by the fiber itself, so the problems of expansion joins, oven, and expansion stress do not need to be considered either during use or on the steel structure of furnaces. The application of CCEWOOL ceramic fiber lightens the structure and saves the amount of steel use for furnace construction. Basically, the installing personnel can fulfill the work after some fundamental training. Hence, the installation has little influence on the insulation effects of the furnace lining.
A wide range of applications
Ideal thermal insulation for different industrial furnaces in various industries
With the development of CCEWOOL ceramic fiber production and technology, CCEWOOL ceramic fiber products have achieved serialization and functionalization. In terms of temperature, the products can meet the requirements of different temperatures ranging from 600 ℃to 1400℃. In terms of morphology, the products have gradually developed a variety of secondary processing or deep processing products from traditional cotton, blankets, felt products to fiber modules, boards, special-shaped parts, paper, fiber textiles and so on. They can fully meet the requirements from different industrial furnaces for ceramic fiber products.
Free of Oven
Easy operation, more energy saving
When the environment-friendly, light and energy-saving CCEWOOL fiber furnace is constructed, no oven procedures will be required, such as curing, drying, baking, complicated oven process, and protective measures in cold weather. The furnace lining can be put in use right upon the completion of construction.
