a. Light weight: The special ceramic fiber material for RTO furnace insulation is 1/30~1/10 of the weight of traditional refractory materials, which greatly reduces the weight load of the RTO furnace insulation structure and reduces the project cost of the RTO furnace;

b. Low thermal conductivity: The thermal conductivity at room temperature is lower than 0.03w/(m.k), the thermal insulation effect is good, and the heat in the regenerator is better kept from dissipating, thereby reducing the addition of auxiliary fuel and reducing operating costs. The RTO furnace adopts ceramic fiber lining for insulation, and the surface temperature of the furnace body is low and the service life is long.

C. Good thermal shock resistance: The ceramic fiber has good thermal shock resistance, which can cope with the alternation of cold and heat caused by the temperature change caused by the periodic replacement of the air inlet of the RTO furnace, and ensure the integrity of the furnace lining. Due to the excellent resilience of the light-weight and high-temperature resistant ceramic fiber lining of the RTO furnace, after the pre-compressed refractory module is installed and the packing belt is removed, an airtight overall refractory layer is formed immediately, and no expansion joints need to be reserved.

d. Strong chemical stability: ceramic fiber is an inorganic non-metallic material, which has strong chemical stability and is not easily affected by the harsh combustion atmosphere inside the RTO furnace.

e. Reduce noise pollution: The ceramic fiber blanket is a random porous refractory material interwoven with ultra-fine inorganic fibers. It has excellent environmental performance of noise reduction, noise reduction, sound absorption and emission reduction. Therefore, the combustion process of toxic waste gas in the RTO furnace is like It is carried out in a muffler with good performance, and the operating noise is very low, which greatly optimizes the production environment of the factory area.
